PROJECT LOCATION:
The project is located in the South Bay subregion. Jurisdictions include the Cities of Gardena, Hawthorne, Lawndale, Manhattan Beach, Redondo Beach and unincorporated areas of Los Angeles County.
PROJECT LIMITS:
This project’s limits are Normandie Avenue between 92nd Street and El Segundo Boulevard, Manhattan Beach Boulevard between Manhattan Avenue and Van Ness Avenue, and Hawthorne Boulevard between Imperial Highway and Manhattan Beach Boulevard. This project also includes Intelligent Transportation Systems (ITS) and intersection operational improvements across the South Bay region.
NEXUS TO HIGHWAY OPERATION, DEFINITION/PROJECT PURPOSE:
This project will complete Traffic Signal Synchronization (TSSP) improvements on Normandie Avenue between 92nd Street and El Segundo Boulevard, Manhattan Beach Boulevard between Manhattan Avenue and Van Ness Avenue, and Hawthorne Boulevard between Imperial Highway and Manhattan Beach Boulevard. Other project components include systemwide coordination timing, Intelligent Transportation Systems (ITS) and intersection operational improvements. The TSSP component of the project will improve traffic signal operations along these routes by upgrading each traffic signal to federal and state standards, providing additional vehicle detection to enable operation as a fully traffic- actuated signal, and install the appropriate components to enable each signal to be capable of time-based coordination. The traffic signals along these routes will be retimed to improve the overall progression of traffic.
Additionally, this project will install any warranted and feasible roadway improvements along the routes to improve overall progression which may include: installation of parking restrictions, modification of signing and striping, and/or minor roadway widening within existing right-of-way to provide for additional lanes. In addition, the Project includes the expansion of the ITS components, including devices to support traffic control system operations and arterial performance measurements. This could include the installation of system detection, additional Closed-Circuit Television (CCTV) cameras, Changeable Message Signs (CMS), and Connected Vehicle (CV) technology. This project should result in an overall improvement in mobility within the region, which will reduce costs associated with moving people and goods, pollution, and other congestion-related factors.
Funds are for design and construction costs. Project sponsor will be required, upon completion of the project, to demonstrate congestion reduction and transit travel time reduction benefits. In addition, project sponsor will be required to credit to LACMTA, as cost savings in proportion to the LACMTA share of the total cost of this grant, any element of the work scope for this project that can utilize previously-installed signal infrastructure (interconnect, signal equipment, etc.)
PROJECT BACKGROUND:
The TSSP routes in their existing condition are unsynchronized or synchronized on the basis of a single arterial, not accounting for crossing arterials. Most intersections along these routes operate exclusively with loop detection and may not be fully actuated. Some intersections feature out-of-standard, smaller traffic signal bulbs which need upgrading, this upgrade my result in mast-arm upgrade requirements. Also, some intersections contain median noses which encroach on sidewalk limits. These existing conditions, among others to be addressed by these projects, contribute to inefficiencies in progression and operation of the subject roadways in the South Bay region.

TIER I PROJECTS – TRAFFIC SIGNAL SYNCHRONIZATION PROGRAM (TSSP):
There are three TSSP projects in this grant: Normandie Avenue, Manhattan Beach Boulevard and Hawthorne
Boulevard. The completion of traffic signal synchronization improvements on these routes will complement other synchronization projects in the area and is part of a long-range plan to synchronize and improve all major corridors in the area. These synchronization projects are the first step toward building a smarter system of roadways.
These three TSSP projects will improve traffic signal operation along the routes by upgrading each traffic signal, providing additional vehicle detection to enable operation as a fully traffic actuated signal, and installing the appropriate components to enable each signal to be capable of time-based coordination. The traffic signals will be retimed to improve the overall progression of traffic along and crossing the route. Additionally, these components of the Project will install any warranted and feasible roadway improvements along the routes to improve overall progression which may include:
modification of signing and striping; and/or minor roadway widening within existing right- of-way to provide for additional lanes. Lastly, this project will upgrade equipment necessary to ensure the operational safety of all traffic signals along the routes which may include: upgrade of highway safety lights; cut back of median noses out of crosswalks; upgrade signal standards and mast arms to increase visibility of mast arm- mounted vehicle heads; and, modify signal phasing.

IV. System-Wide Coordination Timing
This project will augment the scope and magnitude of the system wide coordination timing to be implemented on various arterial routes in the South Bay Forum. The implementation of the traffic signal synchronization improvements identified in this Scope of Work will alter the traffic signal timing of intersecting arterial streets currently operating under coordinated timing. Therefore, revisions to the timing of the crossing arterials will be necessary. If not revised, these existing synchronized routes will experience deterioration in the effectiveness of their current signal timing plans, since the timing was designed on the basis of a single arterial and did not account for crossing arterials. The existing routes will need to be retimed employing timing methods based on a network of synchronized routes.
The project will determine the optimal cycle lengths, phase splits, and offsets for the a.m. peak, p.m. peak, and off-peak periods for the three routes, which may require the use of a modeling software package such as Synchro to be accepted by some of the affected agencies.
This funding will be used to complete the optimizing model, prepare time-space diagrams, prepare timing sheets, install timing in the field controllers, and adjust timing in the field as necessary.
V. Operational Improvements
This element of the scope of work will design and construct appropriate operational improvements that may be recommended during the preliminary engineering and design of the aforementioned arterial routes in the South Bay Forum. This project will implement warranted and feasible operational or intersection improvements to increase the overall capacity, efficiency, and safety of these routes. Typical improvements include: left turn phasing; restriping to provide for additional lanes; minor widening within existing right of way; signing and striping modifications; traffic channelization improvements; and, new traffic signals.
These operational improvements are in addition to the improvements recommended in the scope of work for the arterial route. Additional operational improvements may be identified during pre-design interviews with the affected cities or during field reviews which occur during plan preparation. These operational improvements will only be implemented if they improve the operation and/or safety of the route.
TIER III & IV PROJECTS – INTELLIGENT TRANSPORTATION SYSTEM IMPROVEMENTS:
I. Intelligent Transportation System Improvements
Tasks to be performed include, but are not limited to, the following:
A. Begin preparation of plans, specifications, and estimate B. Complete preparation of plans, specifications, and estimate, C. Advertise construction contract
D. Award construction contract
E. Begin construction
F. End Construction
This element of the scope of work will implement Intelligent Transportation Systems (ITS) improvements to increase the capacity of the major arterials without adding lanes to enable the current transportation system in the South Bay Forum to operate at its maximum efficiency. Using advanced technologies for communications and information processing, the project will expand the improvements installed with prior grants including an Advanced Transportation Management System (ATMS) which is expected to improve the overall regional traffic mobility and reduce traffic delays at County and City maintained intersections along arterial corridors.
The ATMS expansion will provide traffic signal controller upgrades, traffic signal timing revisions, and communications infrastructure necessary to monitor and control the operation and timing of traffic signals; collect and manage real-time traffic information; exchange data and information with other jurisdictions; and monitor signal equipment status. The ATMS will also include the installation of closed circuit television (CCTV) cameras to detect incidents and monitor traffic conditions, communications system(s) to provide field-to-center and center-to-center connections and may include the installation of Changeable Message Signs (CMS) for providing drivers real time traveler information.
Once installed, these CCTV locations are proposed to be connected to the County’s Video Distribution System which will enable the exchange of camera images in real time across jurisdictional boundaries. Appropriate security measures and levels of authority will be incorporated into these ITS elements to prevent any undesired access to data or control of field devices.
Other ITS components to be implemented in this project include the deployment of arterial system detection to support traffic control system operations and arterial performance measurements. These improvements build upon the benefits achieved by the time-based signal synchronization. Arterial system detection allows for the collection of real-time traffic-flow information such as volume, speed and occupancy. This can be coupled with other travel time measurement devices, such as Bluetooth/Wi-fi and Microwave Radar, to provide data to enable more detailed analysis to determine delay, stops, and queue lengths. Calculating and analyzing travel time data from these devices will result in travel time savings and travel time reliability improvements. In addition, the ATMS expansions may include the deployment of elements associated with a Connected Corridors Decision Support System intended to reduce congestion and improve mobility.
Furthermore, the project may also include the deployment of Dedicated Short-Range Communications (DSRC), providing the foundation to implement the next generation of Connected Vehicle (CV) technology.
Expansion of the ATMS provides two-way communications, real-time database management, and control and monitoring functions between the traffic signal controllers and each affected agency. The ATMS allows an agency to control traffic signal operations from its Traffic Management Center and monitor traffic signal operations for malfunctions. This information can assist in both preparing and fine-tuning coordination plans, which are considered a valuable additional tool for use by system operators.
This project may also include the installation and support of elements for the County’s Information Exchange Network (IEN) which will enhance inter-jurisdictional data-sharing for the implementation of arterial traffic management strategies, cooperative efforts in timing plan development and coordinated response to arterial incidents, congestion and special events. These strategies will result in a substantial enhancement of traffic signal coordination and event management capabilities for the affected cities. This project is a significant step towards building a smarter system of roadways.
Due to unforeseen complications, field conditions, actual engineering costs, actual consultant contract amounts, construction bids, and a variety of other factors, it may become necessary to make adjustments to the scope of work and revise the estimated costs as the project progresses. Upon completion of the design phase, detailed summaries of the improvements and cost estimates will be submitted to the Metro project manager and any project adjustments will be made with the Metro project manager’s approval.
