EI Camino Real Traffic u..gnal System City of Redwood City 4.4 F"mal PS&E We will prepare final PS&E. The 90 percent PS&E will be updated in response to project team comments and submitted for a final check and approval prior to the printing of the sets for bidding. Final comments will be incorporated into the design during this task. Design plans, special provisions, structure design, cost esdmaœ, and quantity calculations will be fim1i7.ed and submitted to the City, Caltrans, as appropriaœ. A final set of plans will be submitted in "AutoCAD 12" format. A full set of bidding documents will be prepared. We will process the City's supplied general and standard 1echnical requiremems and add technical specifications. The bidding documents will be delivered in hard copy and on a floppy diskette. TASK 5. COORDINATION TIMING PLANS The following steps are proposed to conduct this task. 5.1 Network Schematic and Data Collection Several elements will be focused upon as part of this task, as follows: Research and obtain all available traffic count data (peak period turning movement counts and 24-hour mid-block counts) for the study inœrsection from respective jurisdictions. Identify any significant modifications anticipated in traffic generation or patterns in the study area for the duration of the proposed project. Obtain other relevant information such as speed data, capacity/saturation parameters, field geometrics information from existing sources or through field data collection, identification of high pedestrian activity locations, and link lengths. Obtain existing signal timing parameters such as: current background cycle length; phase splits; change intervals; phase sequences; and offsets. It is anticipated that existing splits/offsets could be used as the starting point. New turning movement counts will be ob1ained or collec1ed for project intersections. In addition, ADT directional counts will be made. Link-node diagram schematics will be prepared indicating lane geometries, link lengths, and traffic signal phasing. The traffic demand for four scenarios will be analyzed (AM, Midday, PM and off peak periods). 5.2 Subsystem Grouping Analysis: This task will review existing conditions information and identify appropriate subsystem grouping for the 23 study inœrsections for the purposes of signal coordination. We will perform a "strength of attraction" analysis which is based on calculation of a "Coupling index" and other parameters such as cycle length requirements, special traffic needs.
