In HOWLATE, simulated paired driver trials are conducted based on archived roadway travel times to identify how ATIS use impacts trip outcomes. In this report, we expand the application of HOWLATE to investigate the ability of ATIS to improve on-time reliability of freight movements to intermodal terminals based on a case study of the Los Angeles metropolitan area. We focus on how trucks using ATIS perform relative to their counterparts for both fixed departure and flexible departure time conditions. We analyzed the impacts of using ATIS for three types of truck drivers, classified by varying levels of familiarity with the regional roadway network and traffic characteristics and the desired level of on-time arrival. We also analyzed the effect of extending ATIS surveillance to include connector roadways linking freeways and intermodal terminals.119
