Traffic Signal Systems Assessment Report
City of Coronado      1
1 Introduction
Traffic signal systems, when properly managed and maintained, provide for the safe, orderly flow of vehicles, pedestrians, bicycles, transit, and emergency vehicles through intersections and along corridors.

The City of Coronado owns and maintains seven traffic signals, most of which were built in the 1990’s and previously maintained by Caltrans. As infrastructure ages it’s important to periodically evaluate its condition to determine the state of repair. Thisis especially important for traffic signal infrastructure given its role to provide safe and efficient mobility on the City’s roadways. The City engaged STC Traffic to conduct a comprehensive review of the City’s traffic signal system and this report presents the assessment, identifies deficient aspects, and provides recommendations for improvement. This report is organized into four primary parts:

1. Equipment assessment at each location,

2. Operational analysis of each traffic signal,

3. SCOOT system configuration review, and

4. Summary of recommendations.

Traffic signal inventory information is provided in the appendix including a comprehensive spreadsheet for incorporation into the City’s GIS mapping database. A file share site is also provided with digital files including field notes, field photos, excel spreadsheets, and as‐builts which connect the various traffic signal infrastructure elements by location to the findings and recommendations. The combination of this information will be used for cost estimate take‐offs and establish contracting methods for resolution based on the work involved. Ultimately, this report provides the City a roadmap to prioritize improvements that will maintain a good state of repair and implement modern technology for the traffic signal system to operate at its full potential.

1.1 Project Locations
The City of Coronado currently owns, maintains, and operates seven signalized intersections, six along the SR‐75 corridor and one on Orange Avenue. The seven intersections are listed below and shown on Figure 1‐1 on the following page.

1. Orange Avenue & First Street

2. State Route 75 & Pomona Avenue

3. State Route 75 & Avenida Del Sol

4. State Route 75 & Avenida De La Arenas

5. State Route 75 & Rendova Road

6. State Route 75 & Tarawa Road

7. State Route 75 & Tulagi Road
2 Equipment Evaluation
Detailed engineering field reviews of the traffic signalsystem were conducted to inventory and determine the condition of traffic signal infrastructure including conduit, pull boxes, conductors and cable, poles and attachments, detection, controller cabinet equipment, and service pedestals. The field reviews were performed on June 1st and August 17th, 2023. The following subsections are organized by equipment element with tables containing a unique numerical ID for each deficiency type found. Location specific placement, element details, and quantities are illustrated on the traffic signal as‐builts contained in Appendix D.

2.1 Conduit and Pull Boxes
Conduit provides pathways for cables and conductors to connect traffic signal equipment and provides protection from exterior elements. Conduit runs atsignalized intersectionsrange between 1‐ inch and 3‐inch. Rigid metal conduit (RMC) and Polyvinyl Chloride (PVC) are the two conduit types present throughout the city.

Pull boxes provide access to the traffic signal conduit, cables, and conductors for maintenance and construction activities. Pull boxes are positioned to facilitate efficient pulling of cable and wire around an intersection and for interconnect runs between intersections.

The traffic signal pull boxes are made of concrete and reinforced with rebar. Pull boxes are located on the sidewalk and include Caltrans standard sizes #3, #5, and #6. Table 2‐1 lists deficient pull boxes and conduits by intersection.

2.2 Cables and Wire
Cable and wire carry electrical current from the traffic signal controller cabinet to the traffic signal heads and other attached field equipment. Cable and wire run underground in conduit and pull boxes around the intersection to the traffic signal poles. Traffic signal cable typically consists of groupings of 3 and 12 conductors (14‐gauge wire) in a single cable jacket and meets current industry standards. Traffic signal phase wire consists of individual 14‐guage conductors with no cable jacket and is considered substandard.

The schematic drawing below depicts a typical traffic signal cable construction.

1. Blac Polyethylene (PE) jacket

2. Polyester tape separating cable jacket

3. High strength rip cord for jacket removal

4. Polyethylene (PE) for insulation

5. Conductor (stranded 14‐guage wire)
Traffic signal cable and wire was examined and documented for deficient conditions. No traffic signal phase wire wasfound during field inspections. Table 2‐2 below details deficient cable and wire conditions.

3. SR‐75 & Avenida Del Sol 2.2.2 Northeast corner has exposed wires in landscape area.

6. SR‐75 & Tarawa Road 2.2.1 Controller cabinet cables unorganized.

2.3 Traffic Signal Poles
Traffic signal poles provide the structure to attach and display the traffic control devices and provide the conduit for the electrical connections. Traffic signal poles are galvanized steel and are bolted to an underground reinforced concrete foundation that anchors the pole in place. Traffic signal poles vary in size based on location and number of attachments. Wider roads have larger poles with mast arms and traffic signal vehicle heads and signs over the traffic lanes.

Traffic signal poles typically include a luminaire arm for intersection safety lighting. The following traffic signal pole types are present within the City.
 1‐A Pole – 10‐foot height pole with no mast arm or safety lighting.
 15TS Pole – 30‐foot height pole with safety lighting.  Pole with Mast Arm – 30‐foot height pole with mast arm and safety lighting. Mast arms vary in length and number of attachments.

Traffic signal poles are built to last multiple decades. Pole damage typically occurs when the pole is struck by a vehicle and or smaller elements of the pole break due to wear and tear. Pole deficiencies are listed on Table 2‐3.

2.4 Traffic Signal Attachments
Traffic signal attachments include traffic signal heads, safety lights, and signs that are mounted to the traffic signal poles and mast arms.

2.4.1 Vehicle and Pedestrian Signal Heads
Vehicle and pedestrian signal heads are comprised of three main parts: (1) framework, (2) housing, and (3) indications. The signal framework consists of mounting brackets or “pipework” that holds the signal housing to the traffic signal pole or mast arm. The vehicle type signal housing includes terminal blocks, backplate, and visors. The pedestrian signal head has a “clamshell” type housing. Signal indications in the City are Light Emitting Diode (LED) and vehicle signal heads were identified in compliance with standard 12‐inch signal indications. Table 2‐4 lists deficient vehicle signal heads and the associated traffic signal pole and signal indication by movement. Specific signal head placement and quantities are illustrated on the as‐builts contained in Appendix D.

2.4.2 Safety Lighting
Safety lighting is located at signalized intersections and mounted on the end of a luminaire arm at the top of a traffic signal pole. The lights are located on most corners around the intersection to light up the curb return and crosswalk for pedestrian and motorist visibility. The safety lighting is powered from the traffic signal service cabinet’s unmetered section.

Safety lighting throughout the city consisted of a mix of 87W, 103W, 107W, and 137W LED fixtures. Safety lighting observations took place at night and deficiencies are listed on Table 2‐6.

2.5 Detection
Traffic signal detection provides input from the roadway or sidewalk to the controller to identify and determine a roadway user’s need for service at the intersection. Detection types include vehicle, bicycle, pedestrian, and emergency vehicle detection.

2.5.1 Vehicle
Vehicle detection provides the traffic signal controller with the presence and location of vehicles at the intersection and is the basis for informed operation. Without detection the traffic signal system would Attachment 5
Traffic Signal Systems Assessment Report
City of Coronado     7
have to operate on a pre‐timed basis which would lead to significant delay and system inefficiency. There are three type of vehicle detection technologies currently deployed in the City and listed below.  Inductive Loops – Copper cable in a loop configuration set in the pavement to detect changes in the magnetic field above the loop when a vehicle is present. Bicycle loops are also set in the pavement within bike lanes and detect when a bicycle is present. Detection information is conveyed to traffic signal cabinet detector cards via a detector loop cable (DLC) connection.  Wireless Magnetic Sensors – Puck type sensor set in the pavement to detect changes in the magnetic field above the sensor when a vehicle is present. The sensors transmit detection data via a wireless radio connected with traffic signal cabinet detector cards.  Video – Cameras mounted on traffic signal poles and/ or mast armsthat detect changesin itsfield of view when a vehicle is present. Cameras are connected to processors located in the traffic signal cabinet that digitize and interpret the video imagery.

Table 2‐8 below details the vehicle detection types per location.

Detection functionality was investigated/ tested at each location. The video detection system (GridSmart) installed at SR‐75 & Avenida Del Sol is operational but not in use. The system detects vehicles but does not provide outputs to the traffic signal controller. The Sensys detection system has failed at SR‐75 & Rendova and SR‐75 & Tulagi, and both locations are using loop detection. The Sensys pucks at all other locations are either non‐functional or have less than 10% battery life (end of life). Table 2‐9 details detection deficienciesidentified during reviews. Appendix C provides a full inventory of input file detector assignments.

2.5.2 Pedestrian
Pedestrian detection consists of a pedestrian push button (PPB) mounted on a traffic signal pole close to the crosswalk that puts a call forservice to the traffic signal controller when pushed. Accessible Pedestrian Systems (APS) capable PPBs provide audible and vibrating cues to pedestrians when it is safe to cross.

APS assemblies are deployed at City signals with 2‐inch push buttons and meet ADA compliance. The PPB systems are early generation models manufactured by Polara and no longersupported. It isrecommended to replace the entire intersection system when units start to fail. Table 2‐10 provides deficient PPB locations and the as‐built plans in Appendix D provide the intersection pedestrian detection layout.

2.5.3 Emergency Vehicle
Emergency vehicle detection consists of an emitter on the vehicle, either an ambulance or firetruck, that sends a request for service to a receiver mounted on a traffic signal pole. The receiver puts a call into the traffic signal controller which preempts the traffic signal to prioritize service for the approaching emergency vehicle. It is recommended to modernize any legacy systems to current standards. Modern Attachment 5

2.6 Controller Cabinet
Traffic signal controller cabinets house the controller unit and provide the input and output terminal assemblies and power supply for the traffic signal heads and various connected equipment. The controller cabinet is fabricated with anodized aluminum and mounted on a concrete foundation. Controller cabinets within the City are legacy Type 332 and contain a 19” rack for mounting assemblies and plug‐ins. Standard cabinet equipment is shown on Figure 2‐6 and described below.
 Controller – processors that operate the traffic signal.  Conflict Monitor Unit (CMU) – monitors the cabinet and traffic signal for faulty conditions.
 Detector Cards – input file plug‐ins that process signals from field detection systems.
 Output File – provides electrical output to signal heads.  Power Distribution Assembly (PDA) – distributes power for cabinet accessories.

Controller cabinets were found to be in fair to good condition and organized except for Orange Avenue & First Street and SR‐75 & Tarawa Road. These two cabinets should be prioritized among others for replacement and upgrade. Modern ATC type cabinets are recommended.  ATC cabinets provide more room and use smart components that accommodate modern technology and complex configurations that would otherwise require unorthodox wiring or a second cabinet. Appendix B contains an inventory of cabinet equipment by location.

2.6.1 Controllers
The traffic signal controller is the processing unit that operates the traffic signal. City controllers are Siemens 2070LX and 2070E type and operate SEPAC software version 3.52, except for Orange Avenue & First Street which has a legacy McCain 170E controller with BiTrans 200SA software. The 2070LX and 2070E types are newer and in good condition. The Type 170E controller is end‐of‐life and recommended to be replaced with a new 2070 ATC type unit.

2.6.2 Conflict Monitor Unit
The conflict monitor unit (CMU) monitors the cabinet and traffic signals for faulty conditions. Two of the CMUs in the City are modern and capable of remote monitoring while the remaining are legacy type. The legacy CMUs should be replaced with modern units capable of remote monitoring and these would be upgraded alone or together with an ATC cabinet upgrade. Table 2‐14 lists CMU type by location.

2.6.3 Power Distribution Assembly
Power distribution assemblies (PDA) provide the power supply for the controller, plug‐ins, and cabinet equipment. PDA type 2 and type 2L are the two PDA’s types in the City’s traffic signal cabinets and are in good condition. These would be upgraded with cabinet replacements.

2.6.4 Battery Backup Systems
Battery backup systems (BBS) provide uninterrupted power to the traffic signal system. BBS systems consist of an inverter and batteries. BBS systems should be housed in external cabinets to keep bulky hazardous lead‐acid batteries from damaging electronic equipment and to maintain cabinet space and organization. Modern BBS systems have incident log and remote monitor capability with automatic alarm notifications. Figure 2‐7 shows an example of a BBS installed in the traffic signal cabinet and a corroded battery terminal. Table 2‐15 on the next page lists BBS inverters and location.

2.7 Service Pedestal
Service pedestals connect the traffic signal to utility power and contain a meter and control gear that distribute power. The City’sservice pedestals are standard type and generally in fair condition. The service pedestal at SR‐75 & Tarawa Road was noted to be old and in poor condition.

2.8 Communications
Communication systems provide the medium for information exchange between traffic signal field devices the Advanced Traffic Management System (ATMS) which allows operators to remotely control and monitor system health and performance. These capabilities reduce system downtime, allow operators to respond in real‐time to events, and reduce on‐site system maintenance needs.

The City currently has twisted pair copper signal interconnect cable (SIC) spanning from signal‐to‐signal along SR‐75 and connected to ethernet‐over‐copper switches. Fiber optic cable provides a backhaul connection between SR‐75 & Avenida De Las Arenas and City Hall. There is no communication infrastructure at Orange Avenue & First Street.

Data transmission rates are limited with the current copper communication infrastructure. Aged underground copper wire is subject to oxidization which impacts the ability to transmit data. Fiber optic media has a much higher bandwidth capacity than copper and slower degradation rate. It isrecommended to replace copper media with single mode fiber optic communicationsto accommodate current and future technologies. Table 2‐16 and Table 2‐17 list the communications media and network switch equipment at each intersection.

The City’s traffic signal controllers (except Orange Avenue & First Street) communicate with the City’s Tactics ATMS which provides designated personnel the ability to remotely monitor signal operation, produce reports, and modify signal timing. The signals along SR‐75 are controlled by the SCOOT adaptive system which is capable of automatic signal timing adjustment.

3.1 Field Observation and Review
Operations were observed at each traffic signal location over the course of two days, June 7th and 8th 2023. The SR‐75 and Orange Avenue arterials were driven multiple times in both the eastbound and westbound directions to assess typical traffic conditions. AM, Midday, and PM peak periods were observed from 06:00 to 09:30, 11:00 to 13:30, and 14:30 to 18:00.

3.1.1 AM Peak Period
Military traffic is heavy in the morning, primarily on the southbound approach beginning at SR‐75 & Pomona Avenue. Military traffic enters the Naval Base on the east side of the SR‐75 at Rendova Road, Tarawa Road, and Tulagi Road. Additional entrances are located on the west side of the SR‐75 at Tarawa Road and Tulagi Road.

The southbound left turn pockets (Ø1) at both Rendova Road and Tarawa Road form a large queue that spills into the number one through lane despite having adequate storage on the Naval Base entrances.

The left turn vehicle storage is approximately 220 feet.

At 08:30, SR‐75 & Avenida De La Arenasis removed from SCOOT operation and runs in Free mode to allow for a balance between military traffic and access to Strand Way, a frontage road on the east side of the SR‐75 and the primary access for City Hall and nearby destinations.

Morning traffic calms by 09:30 before the midday peak starting at 11:00.

3.1.2 Midday Peak Period
The midday peak period was observed from 11:00 to 13:30. Large volumes of pedestrians(associated with the military base and public) utilize crosswalks at both Tarawa Road and Tulagi Road, and vehicle volumes are heavy on both the east and westbound approaches. Large volumes of cyclists utilize eastbound and westbound pedestrian movements to cross SR‐75. The cyclists complete their movement quickly and the remaining pedestrian crossing time is not utilized which adds to overall intersection delay.

Attachment 5
Traffic Signal Systems Assessment Report
City of Coronado     13
Tarawa Road westbound (Ø4) pedestrian movements will short cycle the Ø1 left turn movement during this time creating congestion on Ø1.

Vehicular and pedestrian demand begins to subside by 13:00 with low pedestrian and vehicular volumes by 13:30.

3.1.3 PM Peak Period
The evening peak period was observed from 14:30 to 18:00. At 14:00, SR‐75 & Avenida De La Arenas reenters into SCOOT operation in preparation for the PM peak. At 14:30, military personnel begin exiting the Naval Base at the Tarawa Road and Tulagi Road intersections. Most vehicles exiting the base travel southbound toward Imperial Beach. A large volume of Naval Base traffic at 3rd Street and 4th Street travel southbound on SR‐75 with mild congestion from Tarawa through Rendova between 15:30 and 16:30.

Vehicle demand was fully served approximately every other cycle.

Traffic demand significantly subsides by 17:00 including minimal pedestrian movements. Most vehicular movements travel northbound from City facilities, parks, and marinas. At 18:00, the bulk of traffic is located at the Caltrans signals north of Pomona Avenue.

An assessment of operation at each individual signal is provided in Table 3‐1.

Isolated from the six City‐Owned signals along SR‐75, with six Caltrans intersections in between it and SR‐75 & Pomona.

Three‐way permissive T intersection with very heavy vehicular and pedestrian movements throughout all three peak periods on all phases.

Pedestrian, Yellow, and Red Clearance intervals do not conform to CAMUTCD compliant standards.

Being isolated from the other city signals, volumes and movements are heavily influenced by Caltrans signals and nearby shops and restaurants.

Westbound left turn is impacted by military traffic during the Midday and PM Peaks, creating a Yellow Trap scenario.
2 SR‐75 &
Pomona
Avenue
This signal is a complex intersection that allows access to Orange Avenue, Strand Way, and Pomona Avenue.

All movements are protected.

With Hotel Del Sol located just several hundred feet south, vehicular bottlenecking occurs during peak periods due to high pedestrian and vehicular volumes.

Military traffic in the AM and Midday peaks utilize thisintersection as a shortcut to and from Orange Avenue & 3rd Street and Orange Avenue & 4th Street after passing through neighboring areas.
3 SR‐75 &
Avenida Del

This intersection is the primary access point for City Hall, the City Recreation Center, several marinas, a large park, and seaside high‐rise condominiums, creating high volumes of vehicular and pedestrian traffic.

NB and SB vehicle movements are permissive.

A third ring exists to include a 10th phase that controls both NB & SB pedestrian movements. If either pedestrian movement is actuated, both movements will run simultaneously in the third ring.

SCOOT operation is disabled between the hours of 08:30 and 14:30 to create easier access to City facilities and residential buildings.

During the Midday peak, the signal becomes a bottleneck to NB & SB movements due to being in Free operation.
5 SR‐75 &
Rendova

Acts as the primary Naval Base access during the AM peak, after which the base gate is closed.

During observation of this signal in the AM peak, the southbound left turn pocket (Ø1) spills onto the main arterial due to SCOOT operation allowing a split as low as 12 seconds and inhibits military traffic from entering the base.

Acts as an exit from Strand Way onto SR‐75 northbound with right‐turn only signage.

Drivers exiting Strand Way were observed throughout the day leaving their vehicles at the limit line and manually placing a Ø4 pedestrian call to halt NB & SB mainline traffic and make illegal left turns onto SR‐75 southbound. 6 SR‐75 &

3.2 Synchro Model Analysis
Synchro analysis models were created based on roadway and intersection geometrics, signal timing and phasing, and traffic demand. Traffic volume data was collected on a typical weekday, Thursday July 20th, during the AM, Midday, and PM peak periods and were coded into the model. HCM 6th Edition Level of Service (LOS) and delay analysis reports were produced for all intersections for the peak periods and the results are shown in Tables 3‐2, 3‐3, and 3‐4. The signal operation is modeled with the intersections operating in actuated‐free mode to compare individual intersection operation to SCOOT system operation. SCOOT logs depicting average saturation were used as the system performance metric.

The operational analysis confirms the AM peak period demand is highest and with primary Naval Base access at Rendova Road and secondary access at Tarawa Road resulting in high delay. Tarawa Road experiences higher delays in the Midday and PM peak periods. The analysis shows low delay at the other intersections. This reflects the individual intersection analysis. Spillover and delay between intersections cause delay across the overall corridor.

3.3 Operational Deficiencies and Recommendations
Operational deficiencies were observed at City traffic signals caused by hardware, software, and/ or adaptive control technology issues. The deficiencies and recommendationsfor each intersection are listed in Table 3‐5. A high‐level overview of deficiencies for each signal during AM, Midday, and PM periods is illustrated on Figure 3‐1, 3‐2, and 3‐3, respectively.

4 SCOOT System Review
Review of the City’s SCOOT adaptive system was performed to detail how the system works. The system runs independently of the Tactics ATMS aside from passing controller data to SCOOT. Tactics does not interface with SCOOT for monitoring, configuration, or other typical ATMS functions. The SCOOT application is used for configuration, monitoring, and reporting adaptive operation. The City is using a legacy version of the SCOOT application that was developed in the 1990’s and provides a limited user interface for reporting, configuration, and real‐time status.

4.1 Configuration
SCOOT operation relies on functional system detection and configuration fine‐tuning based on observation. Initial configuration is provided by YUNEX alongside City engineers to implement desired operational conditions. An on‐site initial observation and configuration takes place, at which time SCOOT components are configured. SCOOT utilizes 4‐character identifiers to name individual configuration settings. The required baseline configuration is listed below.  Intersections (identified as “Nodes”) intended to operate under SCOOT: Each intersection is added and given a unique identifier, with the City utilizing a 6‐character format of J101XX – for example, the first location is J10111, and the sixth intersection is J10161.  System Detectors: System detectors are configured based on their database’s numerical index as defined by NTCIP standards. These are recognized as advanced or stop‐bar detectors, and configured by lane, phase, and approach.
 Links: Links are the spaces between intersections. This assists SCOOT in defining desired offsets based upon volume, occupancy, and speed.

Attachment 5
Traffic Signal Systems Assessment Report
City of Coronado     19
 Plans: Plans are configured that contain different minimum and maximum values for Cycle Lengths and Splits that are controlled by Timetables throughout the day.  Stages: Stages are the identifier for concurrent vehicle movements, with each intersection typically containing four stages. Due to each stage having the possibility of multiple concurrent sequences, subsects are broken out. For example, at SR‐75 & Tarawa, Stage 1 only has a single subsect “A”, containing phases 2 & 6. However, Stage 4 has 3 subsects, E‐F, which identify 3 possible concurrent movements – Ø1 & 6, Ø2 & 5, and Ø1 & 5.  Channels: Channels are utilized as an identifier for each Stage. For example, SCOOT output messages will display a split change to a specific stage with the following syntax: “CHAN MAXS N10131/2 40”, which is fully defined as, “Channel Max Split Node 10131 Stage 2 40 seconds”, meaning that Stage 2 for intersection 10131 is limited to a split of 40 seconds.

Figure 4‐1 below provides a general overview of the real‐time interface, or “Map” provided by Yunex, depicting Nodes, Stages, and Channels for two of the busiest intersections.

4.2 Operational Strategies
SCOOT actively monitors vehicle occupancy at each intersection and congestion along the arterial and will automatically modify the cycle length and offsets for all signals based upon the signal with the highest level of occupancy, with a maximum programmed cycle length of 240 seconds. Split time is then modified based upon occupancy for each configured stage to fit within the new cycle length. Each intersection plan contains different minimum and maximum cycle and split values that will limit or expand splits accordingly. A more saturated stage will be allocated more split time within its minimum and maximum configuration.

The City of Coronado implemented SCOOT to accommodate traffic demands especially related to the Navy Bases and tourist attractions. SCOOT operation is primarily focused on SR‐75 and the signals at Tulagi, Tarawa, and Rendova, all three of which provide access to the Naval Base. During AM and PM peaks, multiple modifiers activate to allow cycle lengths as high as 240 seconds to ensure that traffic does not back up toward nearby residential and shopping areas north of the Naval Base.

Configuration requires extensive knowledge of SCOOT background processes and commands that are intended to be configured and maintained by YUNEX. During observation, deficiencies were observed with queuing at the SR‐75 & Rendova and SR‐75 & Tarawa intersections. In the AM and Midday periods short split configurations for left turn movements limited left turn phase time and caused pockets to overflow and delay mainline movements. These deficiencies were later verified during coordination with YUNEX technical staff on Thursday, October 12th.

Table 4‐1 provides a summary of average cycle lengths determined by SCOOT for the intersections during peaks periods. Figure 4‐2 on the following page provides a graph of how the cycle length was scaled over a 24‐hour period to meet the demands of military traffic at the SR‐75 & Tarawa base access.

7 SR‐75 & Tulagi 240s 60s 60‐140s

4.3 Observations and Recommendations
Coordination with YUNEX traffic revealed that SR‐75 & Avenida De La Arenas, SR‐75 & Rendova, SR‐75 & Tarawa, and SR‐75 & Tulagi locations had Sensys magnetic detection systems in a state of failure. Due to detection failures, the SCOOT system defaults to historical detection data to calculate splits and cycle lengths. When traffic patterns, demands, or other related conditions change SCOOT is blind and can only work with outdated historic data. This effectively negates the SCOOT system adaptive operation and forces it to operate more like a pre‐timed signal since there is no adaption to real‐time conditions.

Attachment 5
Traffic Signal Systems Assessment Report
City of Coronado     21
Figure 4‐2 Tarawa Cycle Length
SR‐75 & Avenida Del Sol and SR‐75 & Pomona Avenue run in an isolated group from the other four intersections on the arterial due to their proximity. This keeps traffic South of Orange Avenue running smoothly but introduces delays on Orange Avenue. This behavior became increasingly problematic during the PM peak astourists and commuters attempt to exit the Orange Avenue corridor heading southbound, while military and City employees attempt to enter the Orange Avenue corridor heading northbound to access the Coronado Bridge.

SEPAC controller software does not display real‐time data of SCOOT controls or system configuration access. This restricts the ability for real‐time changes by maintenance contractors or consultants without direct access to the SCOOT server. The SCOOT data presented on the traffic signal controller front panel is hexadecimal format. Thisformat type is uncommon in the industry and currently can only be interpreted by a select few YUNEX technical support staff.

Upgrades of controller software and the legacy SCOOT user interface to modern software would allow for better optimization of SCOOT and controller operation, bugfixes, and a more streamlined approach to operational strategies.

Alternatives to SCOOT operation would include implementing coordinated signal timing based on up‐to‐ date volumes for AM, Midday, and PM peaks. Coordinated signal timing runs on any manufacturer’s controllers orsoftware. The operation is easily adjustable and fine‐tuned to on the street conditions based on observation, public feedback, and remote monitoring. Additional coordination could be performed with Caltrans for the signals on Orange Avenue to reduce congestion at SR‐75 & Pomona.

5 Summary of Recommendations
Traffic signal inventory information is provided in the appendix including a comprehensive spreadsheet for incorporation into the City’s GIS mapping database. A file share site is also provided with digital files including field notes, field photos, excel spreadsheets, and as‐builts which connect the various traffic signal infrastructure elements by location to the findings and recommendations. The combination of this information will be used for cost estimate take‐offs and to establish contracting methods for resolution based on the work involved. Ultimately, this report provides the City a roadmap to prioritize improvements that will maintain a good state of repair and implement modern technology for the traffic signal system to operate at its full potential.

Appendix A includes a pdf version of the excel spreadsheet of aggregated information and deficiencies.

The excel spreadsheet is sortable and contains the following information.  ID: Deficiency type reference number used throughout document.  Intersection: As referenced in this report.
 Equipment: As referenced in this report.
 Deficiency: As referenced in this report.
 Recommendation: Approach to resolve the deficiency.
 Priority:
o Low:  Deficiencies or equipment upgrades that do not require immediate attention but should be considered as higher priority needs are met.
o Moderate: issuesthat are not the highest priority butshould be addressed assoon as high priority needs are met.
o High: deficiencies that should be addressed immediately.  Deficiency Type: Categorized issue for one or more of the following: Safety, operational, maintenance, and/ or aesthetics.
 Work Force: Listed suitable contracting method to address deficiency, maintenance contractor or third‐party contractor.

The SCOOT adaptive system should be decommissioned. The SCOOT system is outdated and incapable of performing its intended operation due to the failed Sensys detection system. The SCOOT system has been supported ineffectively as the system application is beyond end‐of‐life. This has resulted in deficient progression, staging, and queuing along the SR‐75 arterial. Implementation of coordinated signal timing along SR‐75 and with the Caltrans signals on Orange Avenue would address immediate operation deficiencies on the SCOOT corridor and at the SR‐75 & Pomona intersection. This should be implemented while the City considers the wider ATMS, local software, equipment, and maintenance system services and investments.
