    • Abstract:
      This research study is concerned with the development of a set of procedures for monitoring congestion using GPS and GIS. These procedures are meant to be used more as a planning tool than for everyday traffic monitoring. Under this assumption, a series of travel time runs are conducted along specified routes at specific time intervals. The procedures can also be used for before-and-after studies where the need for specific travel time runs is clearly defined. In either case, GPS data is kept, processed, and stored in a relational database for analysis purposes. This research study focuses on travel time and speed only and not on other variables like flow rates, traffic composition, availability of alternative modes of transportation, and characteristics of the highway network, all of which play an important role in the process of assessing congestion in urban areas. Likewise, this research project does not address specific implementation issues like ranking of congested sections or coordination with other transportation management systems.
