The main objectives of Task Order 4136 are (1) the design of improved freeway on-ramp metering strategies that make use of recent developments in traffic data collection, traffic simulation, and control theory, and (2) the testing of these methods on a 14-mile segment of Interstate 210 Westbound...

This working paper is a preliminary review of the state of the art in the study of the economics of traffic information. The focus is on the different methods used to model the decision process of drivers in a traffic system, and on the effect of traffic information on this process. In addition,...

A method is presented to divide the total congestion delay in a freeway section into six components: the delay caused by incidents, special events, lane closures, and adverse weather; the potential reduction in delay at bottlenecks that ideal ramp metering can achieve; and the remaining delay,...

This working paper discusses two models used to represent the locational behavior of traffic information providers. The characteristics which make traffic information unique as a service good are discussed and exploited in the models to show how the behavior of reformation providers might differ...
