The results show that between 20% and <br />30% of trips on the main north-south routes in the study area could benefit from re-routing to <br />the new extension. In particular, the potential impact of the extension on Santa Rita Road traffic is <br />similar throughout directions and peak hours, except for the southbound direction during the AM <br />peak hour, when its re-routing effect is lower. The reason is that Santa Rita Road users traveling <br />southbound during the AM peak hour are mostly coming from zones that are northwest of the <br />proposed extension, such as West Pleasanton, Dublin, and West Contra Costa County, and going <br />to zones that are southwest of the extension, like Central Pleasanton and South Bay. On the other <br />hand, trips that use Santa Rita Road in the PM peak hour or in the northbound direction generally <br />tend to have one of their trip ends in a zone to the east of the extension and the other one west <br />of it, making it more convenient for them to shift to El Charro Road. <br />Table 1: Potential Re-Routing of Trips by Route <br />Segment Direction Peak Hour Proportion of Trips that Could Benefit from the Extension <br />Santa Rita Road <br />NB AM PM <br />26% <br />27% <br />SB AM PM <br />16% <br />23% <br />Interstate 680 <br />NB AM <br />PM <br />20% <br />24% <br />SB AM <br />PM <br />19% <br />18% <br />Isabel Avenue <br />NB AM PM <br />19% <br />31% <br />SB AM PM <br />35% <br />21% <br />Source: Fehr & Peers, January 2025.
