1. BACKGROUND The purpose of this contract is the development and implementation of new signal timing plans that enhance mobility on arterial roadways. This includes updating the yellow and all-red clearance times per Section 3.6 of the Florida Traffic Engineering Manual. This contract’s effort includes, but is not limited to, the development of traditional signal retiming plans (where needed), non-traditional TSM&O style signal retiming efforts, context sensitive timing plans, work zone mobility, bridge and railroad preemption timing plans, signal performance metrics, special events, some aspects of connected vehicles, and other tasks as directed by the Department. This contract will be a task work order driven contract that will allow the Department to issue work as needed.
2. SUMMARY OF SERVICES The purpose of this project is to provide data collection services and traffic signal retiming engineering services, including before and after studies if needed. The CONSULTANT will be required to work on project specific tasks issued via work orders. The signal retiming engineering service work may require and include data collection services. The CONSULTANT is expected to advise the Department of data collection needs for the development of new signal timing plans. The signal retiming engineering services will include the efforts to develop and/or evaluate signal timing plans that improve traffic flow, reduce delay and stops on the State Highway System while adhering to the procedures and standards found in the Florida Traffic Engineering Manual and the Manual on Uniform Traffic Studies. The scope of the signal retiming services is broadly divided into seven different categories (1) context sensitive signal timing, (2) work zone management, (3) bridge and railroad preemption timing, (4) special events, (5) public complaints/requests, (6) upcoming TSM&O retiming efforts (signal performance metrics and connected vehicles), and (7) other work as directed by the Department. The 7 categories of this contract may require either partial retiming, full retiming, or both depending on the work needed. Full retiming will require development of a full set of optimized timing parameters including cycle length, splits, and offsets. Partial retiming will utilize existing cycle lengths but will evaluate existing splits and offsets and make adjustments as needed to improve traffic flow and safety. The CONSULTANT will be responsible for evaluating all of the State roadways requested for improvements in all retiming categories. The CONSULTANT will make recommendations for plan development and, if approved, will be developed by the CONSULTANT staff. The CONSULTANT will be responsible for working with the local agencies to identify the causes of congestion and will be responsible for coming up with signal timing plans for mitigating these causes through the above mentioned categories. Needed improvements will be recommended by the CONSULTANT to the Department and the signal maintaining agencies for evaluation and approval. Data requirements and a plan for obtaining this data will be included in these recommendations. If data collection services are required and approved, separate task work orders will be issued. Improvements may also be developed and implemented through A-3
separate work orders at the Department’s discretion, including before and after studies if needed. Anticipated activities may include data collection, micro simulation modeling, signal timing plan development, and plan refinement. The Consultant is expected to coordinate with the Department and local agencies in order to avoid duplicating any other signal retiming efforts. In addition, the Department is required to use this contract to help it achieve its goal of retiming all coordinated traffic signals every 3 years and all uncoordinated traffic signals will be retimed every 5 years. The CONSULTANT is to continually coordinate with District staff to ensure that all eligible efforts associated with this contract are tracked and are providing substantial support to the Department in meeting this goal.
