Unless specifically requested, NDS will ensure that data is not collected on days with forecasted extreme weather conditions; in the immediate aftermath of a natural or other disaster affecting area traffic flows; in close proximity of a city-designated holiday/major weekend holiday/extended weekend; on Mondays, Fridays, or weekends unless authorized; on days where normal traffic patterns are affected by nearby construction projects or scheduled special events; and when the local school districts are not in regular session. NDS will clearly communicate to the City any conditions or circumstances that could negatively impact the data collection effort.
SAFETY
At NDS, safety is a top priority reinforced through mandatory annual training for all employees, monthly safety meetings, and role-specific instruction covering PPE, equipment handling, driving practices, work zone safety, public interaction, and emergency protocols. Every crew member signs off on each safety topic to ensure full understanding and accountability.
NDS provides all necessary PPE in compliance with OSHA and local regulations, and equips all vehicles with high-intensity beacons, reflective markings, cones, warning signs, GPS tracking, and front- and rear-facing cameras to monitor and document driving behavior in real time. Daily reviews of driver data help enforce a consistently safe and law-abiding workforce.
DATA COLLECTION
NDS performs all tasks in accordance with the procedures and specifications identified in the latest California Manual of Uniform Traffic Control Devices, the FHWA Traffic Monitoring Guide, the Highway Capacity Manual, and generally in accordance with sound traffic engineering principles. NDS will not enter private property without permission of the private property owner.
Turning Movement Counts
Equipment
NDS utilizes our proprietary camera systems for average daily traffic counts, turning movement counts, queuing, pedestrian counts, bicycle counts, delay studies, gap studies, and many more observation-based studies. Our units contain the most technologically advanced hardware available for temporary data collection. These systems are capable of recording for any duration of time, in extreme weather conditions, and in all lighting conditions. NDS units are capable of capturing any size intersection, segment, or other points of observation through the use of one or more synced cameras. Additionally, NDS can modify the resolution, frame rate, and bit rate to meet the needs of extremely high-resolution projects up to 1080p. At any

[email protected] | www.ndsdata.com RFP No. 25-26-02
resolution, NDS cameras cannot capture license plate information. NDS camera units do not require external power for operation. All videos contain date and timestamp information clearly displayed during review.
Methodology
NDS cameras are mounted at the base of an existing infrastructure element using an aluminum chassis with non-harmful rubber pads as contact points. NDS can utilize a variety of infrastructure elements for installation, such as poles, street signs, and trees. Installations do not obstruct visible signage. Each camera contains a telescopic pole that extends over 21 feet vertically for an unobstructed view of the intersection or other desired point of view. The equipment retrieval process removes all visible evidence of the camera unit.
Data Reduction
After the data collection period has ended, video files are promptly transferred to NDS’ centralized Google Cloud Server for video delivery preparation, data reduction, quality review, and data delivery preparation as defined in the section below labeled “Quality Control / Processing”.
NDS utilizes both proprietary machine learning and manual reduction methods to capture, classify, and audit data by road user classification. The NDS machine learning algorithms are fine-tuned to capture vehicle volumes, axle-based classifications, and speeds. NDS has also spent well over a decade building a human driven video team with various levels of quality control to capture pedestrians, bicycles, turning movement counts, and other non-motorized classifications. Through numerous empirical studies conducted with a variety of well-known and lesser-known providers, NDS has determined the accuracy of algorithmic video watching for pedestrians, bicycles, turning movement counts, and other non-motorized classifications to be unpredictable, providing subpar accuracy. In response to these deficiencies, NDS utilizes an in-house video reduction team along with a multi-stage QAQC process that consists of extremely detailed and tedious training protocols for all video watchers. Our video team is broken into three departments: the video review team, the video spot checking team, and the algorithm team. Further details are outlined below in the section titled “QUALITY CONTROL / PROCESSING”.
Deliverable
Data will be delivered in Microsoft Excel format. Data will be in 15-minute intervals and the peak hours will be identified.
Volume, Classification, and/or Speed Average Daily Traffic Counts Equipment
NDS proposes the use of NDS Aura video cameras for volume, speed, and classification (FHWA 1-13) data collection on street segments. The NDS camera unit overcomes several machine-driven limitations such as poor performance in congestion, limited free-flowing placement options, and poor performance in extreme hot or cold weather conditions. In addition, redo rates are lowered significantly by avoiding unpredictable road tube issues. However, should road tube installation be preferable to the City, NDS is capable of meeting all requirements and deadlines using MetroCount machines.
Methodology
General and camera-related data collection practices mirror those outlined in the section labeled “Turning Movement Counts.” The remainder of this section will focus on road tube methodology.
ATR installations occur the day before the requested start date to ensure that data collection begins at midnight unless otherwise directed. A pre-determined safety plan is executed upon both site arrival and departure. Machines are installed in free flow traffic conditions outside of auxiliary lane storage. Consideration is given to the type of street and surrounding land usage when choosing the equipment and method for installation. To achieve optimal conditions, equipment is installed at a minimum of one thousand feet away from intersections or ramp junctions. For smaller segments, counters are installed midblock and may be staggered to produce the best results. To account for higher sensitivities typically present on residential street segments, NDS staff utilizes low-profile pneumatic tubing to complete installations during the daytime hours whenever possible. Installation includes securing the machine with a lock and chain to existing public infrastructure, nailing the knotted/closed end of the tubes at the far side of the lane, stretching the tubes to the edge of the roadway,

nailing down the open end of the tubes, adding tape to secure the tubing, plugging the loose ends of the tubes into the open machine ports, and monitoring the machine while vehicles pass by to ensure that data is being recorded accurately.
Equipment installed for multiple days will be checked to ensure that the data collection effort has not been interrupted and that the equipment is still in operable condition. After the collection period has ended, equipment is completely and safely removed from the site so that there is almost no visible evidence that the installation took place.
Deliverable
Data will be delivered in Microsoft Excel format. Data will be in 15-minute intervals with hourly totals per direction of travel.
A final report in Excel will include the street name, segment description, date and day of the week the count was conducted, hourly totals, AM totals, PM totals, and daily totals. A paper copy of the final report and an electronic file of the raw data in original format will be provided to the City.
Intersection Approach Counts
Equipment and methodology mirror those outlined in the section labeled “Turning Movement Counts” and “Volume Classification, and/or Speed Average Daily Traffic Counts.”
Deliverable
Data will be delivered in Microsoft Excel format. Data will be in 15-minute intervals with hourly totals per direction of travel.
Data will include all legs of the intersection and be in 15-minute intervals with hourly totals.. A final report in Excel will include the street name, segment description, date and day of the week the count was conducted, hourly totals, AM totals, PM totals, and daily totals. A paper copy of the final report and an electronic file of the raw data in original format will be provided to the City.
Pedestrian & Bicycle (& Other Non-Motorized) Volume Counts Equipment and methodology mirror those outlined in the section labeled “Turning Movement Counts.” NDS is capable of capturing this information at intersections, screenlines, trails, campuses, event facilities, and most other areas where this information is required.
Deliverable
Data will be delivered in Microsoft Excel format. Data will be in 15-minute intervals. For counts done at intersections, data will include all legs of the intersection. If requested, vehicle turning movement counts can accompany the pedestrian/bicycle count. If classification by age (or by some other attribute) is required, the deliverable will reflect this.
Origin and Destination Studies / License Plate Surveys
Equipment
NDS uses custom-designed field templates or audio recorders for origin and destination studies/license plate surveys.
Handheld cameras on tripods, overhead cameras, and drones can also be used. For efforts that exceed the capabilities of the aforementioned methods, Bluetooth technology can be used to determine origin-destination patterns. The BlueTOAD Spectra combines two wireless technologies, Bluetooth® (2.4 GHz) and Dedicated Short Range Communications (DSRC, 5.9 GHz) installed within one roadside device. DSRC coupled with BlueTOAD Spectra real time and historical Bluetooth® device detection can help guide safety and mobility applications in Connected and Autonomous Vehicle (CAV) initiatives, while providing synchronization with transportation agency Travel Time and Performance Measures objectives.
Methodology
Data collection methods vary: live technicians may manually record license plates, while handheld cameras on tripods capture plates in high-traffic or fast-moving areas, though accuracy may be around 75% due to blurriness and transcription errors. Overhead cameras and drones can track vehicles more effectively, with overhead cameras ideal for monitoring attributes and platooning and drones covering areas with minimal aerial obstructions. Additionally, technicians can use voice

Travel Time / Speed Data
Equipment
Laptop and GlobalSat BU-353-S4 USB GPS Receiver. NDS also offers average corridor travel time and speed using Google crowd-sourced data.
Methodology
NDS will analyze the beginning and end of each corridor to determine appropriate routing throughout one or more corridors. NDS collects travel time information using highly trained and experienced drivers paired with external GPS antennas. All drivers are individually trained and tested to ensure adherence to appropriate driving behaviors, node identification, and route assignments. All routes are extended upstream and downstream to ensure that vehicles travel through the route start and stop points at the speed dictated by local traffic. NDS field staff provide detailed notes pertaining to delays encountered throughout each run. This information is timestamped and classified by the source of the delay. NDS uses the floating car technique as defined in the MUTCD unless otherwise directed. We offer either PC Travel or Tru-Traffic as possible post processing platforms for reporting. Delay sources will be timestamped and classified as: signal, congestion, stop sign, pedestrian, or other (written as instructed or experienced).
For Google crowd-sourced data, data is collected by route and/or by link. A link is defined as two (2) points of interest. A route is defined as more than one link combined together. User-defined parameters include:
Collection interval frequency - can be as low as 1 minute Day(s) of collection – Current and future days are available for collection Hour(s) of collection – Specific hours can be selected by specific day Deliverable
Travel time summary information will be delivered in Microsoft Excel format and/or PDF. Travel time summary includes travel time in seconds, number of stops, average speed, and total delay.
The deliverable report from using Google crowd-sourced data includes both a tabular and graphic representation of the average speed per interval as well as the average travel time per interval for each link and each route.

Methodology
Radar Speed Surveys are conducted in accordance with the Department of Motor Vehicle Regulations and the Manual on Uniform Traffic Control Devices (MUTCD). Collection sites are investigated in advance to identify conditions that would adversely affect data accuracy such as proximity to speed bumps, proximity to intersections, locations with steep grades, and any other conditions that could impact normal vehicle speeds. Surveys are not to be conducted during inclement weather or when the roadway is wet. Surveys are not to be conducted during atypical conditions such as road construction, detours, or traffic accidents.
A sample of free-flowing passing cars will be selected with careful attention to ensure that the sample represents the entire traffic stream. In platoon flow, only the first vehicle in the platoon will be selected. All vehicles traveling at less than 40 mph and within 200 feet of the lead vehicle or more than 40 mph and less than 350 feet from the lead vehicle is considered to be in platoon. Field staff are trained to be inconspicuous so that driver behaviors are not affected by their presence. Deliverable statistics include 50th percentile, 85th percentile, 10mph pace, # in pace, percent in pace, % / # below pace, % / # above pace. Additional statistics can be added at no additional cost.
Deliverable
Data will be delivered in Microsoft Excel format. Speed parameters, such as 50th Percentile, 85th Percentile, and 10 MPH pace, can be included.
QUALITY CONTROL / PROCESSING
NDS leads the industry with the most detailed and sophisticated quality control processes nationwide. At the field level, all equipment undergoes regular maintenance and testing to ensure full functionality. Field personnel are specifically trained to conduct a preliminary inspection of the collected data, allowing for expedited communication surrounding possible disruptions to the data collection effort. Post data submission, NDS has four departments dedicated to quality control after data is submitted from the field: the Audit Department, the Video Department, the Processing Department, and the Analyst Department. These departments are centralized at NDS headquarters and are responsible for the quality control, processing, analysis, file preparation, and data delivery of all data collected by NDS throughout the nation. These departments have extensive experience working with all NDS services, data collection best practices, data collection formats, contracts, and data delivery formats.
Audit Department
The Audit Department is responsible for the timely submission and careful review of all field data throughout the company.
This department tracks nationwide scheduling to prepare for video and data uploads. Videos are scrubbed thoroughly to ensure that all time periods are present, the viewing angles are consistent, and to confirm that all data collection requirements can be met. Pictures are also viewed carefully to verify the traffic control plan, that all appropriate work zone safety equipment was utilized, and that cameras were installed according to NDS protocols. All other data submissions are checked per manufacturer recommendations and compared to client/contract requirements to confirm compliance. This department works closely with our Operations Department, providing the necessary feedback to optimize our national operations.
Video Department
The NDS Video Department manually reviews over 1,000,000 hours of video annually. This department is divided into three teams: video review, video spot checking, and algorithm. All teams are well-versed at performing counts with detailed vehicle, pedestrian, bicycle, and micro-mobility classifications throughout the nation. NDS captures all 13 FHWA classifications based on axle, not by length. This team is also experienced at conducting a large variety of observational and custom-developed studies throughout the nation. Due to our training, standards, and protocols, NDS proudly achieves an accuracy rate of 98%/±2% and ±2 vehicles for volumes up to 100 vehicles.

Video Review Team
The video review team is responsible for site verification, auditing all required hours, confirming the required field of view, reporting any anomalies disrupting the flow of traffic, recording hourly traffic observations, recording hourly weather observations, and counting the details in the video per data collection task requirement. Each video reviewer is trained extensively on all study types and vehicle classifications. Video reviewers are not permitted to count live data until over 200 video hours have been watched and verified as at least 98% accurate.
Video Spot Checking Team
The video spot checking team is responsible for separately spot checking all classifications and data requirements present in video related projects for at least one 15-minute interval per two (2) hour period. If a comparison between the spot check and the original count reveals a variance greater than 2%, the entire two (2) hour count period that was spot checked is re-reviewed and re-submitted to the spot-checking team. This process will repeat until the accuracy threshold is met. Spot checks are completed for both algorithmic and manually reduced video to ensure that our accuracy thresholds are met. If spot checks find that site-specific variables had an impact on the accuracy of our machine learning algorithm, NDS will manually review all video at no cost to our clients. This will then be used to continue training our algorithm to account for the multitude of uncommon variables that exist.
Algorithm Team
The algorithm team is responsible for the initial software setup needed to accurately post-process video through our algorithm. This team is responsible for ensuring consistency in detection throughout the entire period of collection and making adjustments to the detection area as needed. In order to achieve best-in-class accuracy, the NDS algorithm separates images of vehicles where it lacks confidence for proper manual classification by the algorithm team. This team carefully reviews confidence ratings reported from our system to verify both volume and classification accuracy. Spot checks are performed for these videos as described in the section above titled “Video Spot Checking Team” to ensure accuracy and consistency in both daytime and nighttime conditions.
Processing Department
The processing department is responsible for scrutinizing client requests to ensure that all data collection requirements have been met and submitted for the project. This includes confirming the location, installation layout, orientation, presence of all required time intervals, movements, classifications, sketches, pictures, GPS coordinates, field sheets, and all necessary site data.
The processing team converts the data from its raw format to the deliverable formats and performs a preliminary data integrity check. This involves checking the data for abnormal data sequences such as abnormal spikes or valleys in the data set, inconsistent data compared between days, inconsistent historical comparisons, or illogical data patterns. Concerns about the data quality at this stage result in additional video spot checks (if applicable), data verification through sampled recollection, or consultation with the analyst department.
Analyst Department
The analyst department is responsible for conducting a secondary review of all data components, checking for data consistency throughout a corridor utilizing all available data resources, converting data into the contract specified deliverable, and preparing the delivery package as outlined in the contract. As part of the review, a comparative analysis is performed between all data points within a project. This team is dedicated to validating the relational integrity of these data points utilizing additional spot checks, video footage, historical data, and additional field observations as necessary. To prepare data in its deliverable format, the analyst utilizes a variety of tools (including custom program development) to ensure that all data format conversions stay consistent throughout each contract.
DATA PREPARATION AND SUBMITTAL
The processing and analyst department will collect, consolidate, format, and prepare each delivery to the City following the collection of the data.
