This report presents the findings of a feasibility study which developed a simulation testbed for the Santa Monica freeway corridor. The study involved performing an evaluation of the state-of-the-art models for Advanced Traffic Management and Traffic Information Systems (ATMIS) on freeway corridors. The evaluation was based on the model capabilities, input data requirements and output options, with focus on the record of real-life calibration, validation and practical application of the models. The findings show that the CORSIM and INTEGRATION models have the higher probability of...

This report describes the development process of the Bus Rapid Transit Performance AssessmentGuidebook (BRT PAG) Tool, which provides a decision support means for tool users to understand at a high level the benefits and costs associated with implementing bus rapid transit systems. The BRTPAG Tool is based on a conceptual framework consisting of BRT system strategies; stakeholder groupings; impacts of individual BRT system strategies; measurement methods used to analyze the impacts that BRT system strategies have on different stakeholders; and quantitative estimates of benefits and costs...

This study can be viewed as a preliminary exploration of using regression analysis to evaluate long-run traffic management system performance. Four main traffic management systemsin the Twin Cities metro area --- Ramp Metering System, Variable Message Signs (VMS), Highway Helper Program, and High Occupancy Vehicle (HOV) System were evaluated based on multiple regression models. Link speed and incident rate were employed as the response variable separately. Consequently, regression analysis can be a simple and effective research method for testing the macroscopic association between traffic...

In this document a framework for evaluating ITS projects is developed. One of the central issues addressed is whether ITS projects are distinctly different from other more conventional transportation projects and thus the traditional decision methods such as Benefit-cost analysis cannot be used. The answer is mixed. The decision models used in the past are still relevant, however, these have been applied in an environment in which there was a well developed data base. The models identified, selected, assembled and evaluated data to make judgements as to whether the proposed projects were...
