Benefit Summary HTML
In 2007, the California Department of Transportation (Caltrans), in partnership with the California Center for Innovative Transportation (CCDI), conducted a pilot test to determine if the roadside display of real-time trip times for highway and transit modes to the same destination in the Bay Area influenced commuters’ mode choice. The premise underlying the test was that motorists would be more likely to select transit when facing congested conditions and upon receiving the information that they would arrive more quickly using transit. The pilot test consisted of three Changeable Message Signs (CMS) deployed before exits to two major transit stations (Millbrae and Redwood City). The CMS displayed three types of information 1) highway travel time, 2) Caltrain Baby Bullet, the commute-hour express service, travel time, and 3) the next train departure time. The CMS only displayed the travel information during peak hours and only when transit provided a time savings compared to highway travel. An evaluation of the effect of the CMS on commuter behavior and opinion used qualitative findings gathered from traveler surveys and quantitative data based on transit ridership counts and parking counts.
