Travel Time Assessment – Key Links/Routes The intersection operations analysis presented above was also used to estimate travel times along several routes that may be affected by the extension. Figure 7 presents the key routes. Table 4 presents the routes that were evaluated for this analysis in the northbound and southbound directions during the weekday morning and evening peak periods. The travel times compare with and without extension scenarios. These results suggest the extension has a positive impact on reducing travel times along Main Street and Santa Rita Road, especially during the AM peak hour. First Street is another roadway where travel times are reduced by the proposed extension, while travel times along Bernal Avenue in the northbound direction, given its traffic volume increase, are greater with the extension. There does not appear to be a substantial impact on travel times along Isabel Avenue.
