  • Techniques for Estimating Vanpooling Demand
    Techniques for Estimating Vanpooling Demand
    Christiansen, Dennis L. ;
    Maxwell, Donald A.
    1982-08-01 | PDF
    It has been found that allowing vanpools to use high-occupancy vehicle (HOV) lanes is an effective means of increasing the vehicular utilization of those facilities. Vanpools are readily identifiable and, as a result, can be relatively easily controlled. They are compatible with the Houston philosophy that only authorized vehicles be permitted to u ...
