| 摘要： | This report describes a system designed to provide Single Occupancy Hybrid Vehicles (SOHVs) restriction messages dynamically to drivers through variable message signs. This system will allow California to comply with federal requirements (that Single Occupancy Hybrid Vehicles (SOHVs) must be excluded from High Occupancy Vehicle (HOV) lanes if their speed performance is degraded) by providing a way for Caltrans Traffic Management Centers (TMCs) to determine whether or not SOHVs should be permitted in HOV facilities. In turn, they could disseminate that information through control of variable message signs that indicate to drivers which vehicles are permitted in the HOV lane. The work performed under this project represents a step forward to understanding various HOV restriction scenarios and their impact on HOV lane and mainline congestion. In this project, researchers studied, via simulations, the effects of permitting or restricting eligible single occupant hybrid vehicles (SOHV) from use of HOV facilities. The team simulated various control scenarios on a selected corridor (25 mile segment of California Interstate-210 Eastbound). Results from the simulations showed that reduction in vehicles eligible to use HOV lane (not just SOHV but any vehicle) could reduce not only the delay experienced by HOV vehicles but also the total system delay. This high-level system design was presented in sufficient detail to allow implementation as software or a relational database. Implementation would allow for the simulation of traffic scenarios to be tested against real data. This should be the next step in the development of this system. |
