| Summary | Published in March 2004 IOT SERIAL No. 93-27-693, 518pp. Advanced Traveler Information Systems (ATIS) and Advanced Traffic Management Systems (ATMS) provide an array of capabilities aimed at alleviating traffic congestion in urban networks however, only limited and coarse evaluations of the effectiveness and benefits of ATMS/ATIS have been discussed. This proposal focuses on network flow analysis by considering individual tripmaker decision-making processes and their interactions in traffic networks under advanced information and control systems. A day-to-day dynamic conceptual framework is proposed to model the traffic system in the context of ATIS/ATMS from an individual tripmaker perspective. In this framework, two levels of tripmaker decision-making processes are identified: 1) day-to-day dynamics and 2) real-time dynamics. Day-to-day dynamics consider tripmakers' choices of departure time and route according to indifference bands of tolerable "schedule delay" defined as the difference between the user's actual and preferred arrival times real-time dynamics consider tripmakers' en-route switching decisions in response to prevailing traffic conditions. Under native traffic characteristics and user behavior models, the research team will develop an evaluation tool for ATMS/ATIS through the project, titled ‘Demonstration Projects for Regional Intelligent Transportation Systems’. |
