This paper describes an innovative Integrated Transportation Management System (ITMS) Operational Test project for the I-93 corridor north of Boston, funded by the Massachusetts Highway Department and Federal Highway Administration. The goal of the operational test is to monitor the performance of traffic on the I-93 corridor, including alternate routes, and to provide real-time information on the performance of these routes to motorists on I-93 using variable message signs (VMS). There are multiple objectives to the operational test project. They include: assess the benefits of a dynamic, en-route motorist information system for I-93 southbound; evaluate the impact of this system on motorist behavior; determine the feasiblity of integrating predictive commuter information with signal control decisions; and determine the feasibility of dynamic traffic assignment (DTA) models to provide useful and reliable traffic management and traveler information. The overall objective of the operational test project is to further the development of Advanced Traffic Management Systems (ATMS) and Advanced Traffic Information Systems (ATIS) in Metropolitan Boston as a means of improving highway safety, reducing congestion, improving air quality, increasing mobility, and furthering economic productivity. |
