  • Modelling Carpool and Transit ParkandRide Lots
    Modelling Carpool and Transit Park-and-Ride Lots
    Allen, William G.
    1997-01-01 | PDF
    Park-and-Ride (PnR) lots are an increasingly common element of many areas plans for air quality conformity. However, few, if any, travel models estimate the impacts of carpool PnR lots, and it is not at all clear that they always improve air quality. Many travel models in the larger urban areas accommodate transit PnR lots, but, as with carpool PnR ...

    Feasibility of applying the Global Positioning System to locate motor vehicle crashes : final report.
    Miller, John S ;
    Karr, Duane
    1997-01-01 | PDF
    Countermeasures for motor vehicle crashes are often determined after extensive data analysis of the crash history of a roadway segment. An important factor that drives the value of this analysis is the accuracy, or precision, with which the crash is located. Yet this location is only as accurate as the estimate of the police officer. In light of th ...
