Origin-Destination studies are often used in transportation planning to determine the travel patterns (origin-destination matrix) of vehicles and goods in a particular area. Given these travel patterns, the impacts of alternative solutions to current and future transportation problems can be evaluated. Therefore, it is important that the travel patterns be accurately measured. However, it is not always clear what data collection method should be used to obtain the type of data needed, while maximizing quality and minimizing the time and cost. The objective of this research is to review both conventional and experimental techniques for roadside station OD studies, and make general recommendations for the best OD study technique and data collection method, given the roadway characteristics and traffic conditions. |
