Evaluating the Impact of High Occupancy Vehicle (HOV) Lane Access on Plug-In Vehicles (PEVs) Purchasing and Usage in California

In California, there are two types of high-occupancy vehicle (HOV) access: 1) White decals, available to an unlimited number of qualifying federal inherently-low-emission vehicles, mostly 100% battery electric and fuel cell electric vehicles (BEVs and FCVs) and 2) green decals, which are available to the first 40,000 applicants that purchase or lease cars meeting California's transitional zero emission vehicle (TZEV) requirement, mostly plug-in hybrid electric vehicles (PHEVs). Current discussion focuses on whether to add more green decals beyond the current limit of 40,000. More decals will sell more PHEVs but will also increase the number of cars on HOV lanes and may reduce the lane performance and the revenue of high occupancy toll lanes (HOT). By developing a better understanding of the costs and benefits of HOV decals as an incentive, policy can be tailored for maximum benefit. The analysis shows that PHEVs with greater all-electric range provide much higher levels of zero-emission travel per HOV mile. Policy makers can take this factor into account when determining the level and duration of the HOV incentive.
