TravTek Evaluation Modeling Study

摘要

The following report describes a modeling study that was performed toextrapolate, from the TravTek operational test data, a set of system wide benefits and performance values for a wider-scale deployment of a TravTek-like system. In the first part of the modeling study, the INTEGRATION simulation model was enhanced and calibrated to produce a model whose driver and in-vehicle system parameters were representative of the behavior that was quantified by various TravTek field test in Orlando, Florida. In the second part of the study, a coded traffic network and created with properties that were representative of the traffic conditions observed in Orlando during the course of the TravTek operational field test. Nine Measures of Performance (MOP's) of the TravTek system were then estimated using the model; the total trip travel time; the total distance traveled; the number of stops incurred; and the number of missed turns experienced; as well as the average estimated fuel consumption; vehicle emissions of hydrocarbon (HC); carbon monoxide (CO) and oxides of nitrogen (NOx) per vehicle; and the expected accident risk.
