  • Abstract:
    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.
