摘要：	To repay bond debt for new toll roads, investors will depend on toll revenue, an uncertain source. Studies have found that traffic on toll roads is initially low, and grows slowly over time as motorists become aware of the time savings and other benefits of a toll road. Given this situation, this study was initiated by TxDOT to investigate the potential of using Advanced Traveler Information Systems (ATIS) to enhance the operations of both tolled and non-tolled roads. Enhanced diversion of traffic to toll roads would have two benefits: increase toll road usage, and reduce congestion on non-tolled roads. Evaluation of the dual benefits is the primary objective and the essence of this study. The research team first synthesized the state-of-the-art in ATIS implementations. Then a commuter survey was conducted in Austin, Texas to examine commuters travel patterns, preferences and requirements on traveler information, and attitude toward toll roads and ATIS implementations. Next, based on the survey results, a simulation case study was conducted on the transportation network of Austin, Texas using DYNASMART-P model. Finally, ATIS benefit and cost analysis, implementation issues, technologies, funding opportunities, and potential business models were investigated. It was found that the impact of traveler information on commuters route switching and toll road choice is positive. The simulation results indicate that providing traveler information could significantly increase toll road (SH 130) usage and toll revenue. As a result of a portion of traffic diverting to toll road, the traffic operations on the non-tolled alternative route were improved. Deploying ATIS can be a very promising method to increase toll revenue and relieve traffic congestions on the non-tolled alternative route. / NOTE: Technical rept.
