To the Honorable Mayor and City September 9, 2002 Subject Award of Contract - Arterial Traffic Signal Interconnect Project (RTSOP II). Recommendation ~Approve the Contract Documents and award contract for the Arterial Traffic Signal Interconnect Project (RTSOPII), to the lowest responsible bidder, S. G. Barber Construction, Inc. of Belmont, California, for their Iow bid of $278,440.00. Background This project is very similar in nature to the Regional Traffic Signalization/Operation Program (RTSOP1) - Downtown Traffic Signal Interconnect Project that was completed in 2000. The State has provided the majority of the funding for both projects (88.5%). The goal for the program is to increase the efficiency of traffic corridors through interconnection and coordination to reduce air pollution. The grants were applied for in 1993, with Phase 1 starting in 1998 and completed in 2000. .-. The scope for Phase 1 of the project covered the signals physically located downtown. It involved pulling 'interconnect' wires from each intersection that were not connected, thereby forming a 'network' of traffic signals. Phase I also replaced all the controllers, or the computer at each intersection, and wiring to City I-~11 for 33 intersections. Out of the $383,588 final cost for Phase 1, $327,000 was paid by grant monies. Phase 2 will interconnect the out-lying signals such as those in Redwood Shores', along Seaport Boulevard, Farm Hill Boulevard, Alameda de las Pulgas, and south of Woodside Road along Middlefield Road. Last year we advertised this second phase, but did not award the bid because they came in much higher than the availab!e budget. The project has since been redesigned and the scope reduced. The project was redesigned using three (3) !elephone line connections in place of the radio connections which caused to bid last year's bid to be so high. This reduced the project.cost to the original budget. The centralized computer system allows remote accessing to each controller possible from City Hall, making programming and data acquisition more convenient, since staff does not have to visit each controller for the task. Groups of controllers can 'also be programmed at the same time. However, this convenience does not change the fact that signal coordination is notan end-all solution to traffic congestion. For coordination to be beneficial, many variables have to be met, including the willingness to sacrifice the level of service from the non-coordinated directions, appropriate traffic volume, and -¸1-
