摘要: The fundamental principle of intelligent transportation systems is to match the complexity travel demands with advanced supply-side analysis, evaluation, management and control strategies. A limitation lack basic knowledge at network level. Modeling sensor technology primarily limited aggregate parameters or micro-simulations based on distributions behavior. Global positioning (GPS) are one several available technologies that allow individual vehicle trajectories be recorded analyzed. Potential applications GPS implementation in probe vehicles deliver real-time performance data complement loop other from sampled households record route choice flexible GPS-based collection unit has been designed which incorporates GPS, logging capabilities, two-way wireless communications a user interface an embedded system eliminates (or minimizes) driver interaction. This paper describes design initial tests this unit.
