INTEGRATION OF THE GLOBAL POSITIONING SYSTEM AND GEOGRAPHICAL INFORMATION SYSTEMS FOR TRAFFIC CONGESTION STUDIES
This paper describes an integrated Global Positioning System (GPS)--Geographical Information System (GIS) developed by the Transport Systems Centre to collect on-road traffic data from a probe vehicle. This system has been further integrated with the engine management system of a vehicle to provide time-tagged data on GPS position and speed, distance traveled, acceleration, fuel consumption, engine performance, and air pollutant emissions on a real-time basis. Data are handled within a GIS and can be processed and queried during data collection or saved to a file for later analysis. A case study application of the system is described focusing on studies of congestion levels on 2 parallel routes in a major arterial corridor in metropolitan Adelaide, South Australia. As part of these investigations, a discussion of the nature of traffic congestion is provided. The computation of these parameters for the study corridor on the basis of data collected from the integrated GPS--GIS system is given. The GIS provides a database management platform for the integration, display, and analysis of the data collected from GPS and the in-vehicle instrumentation. The database so generated provides a rich source of information for studies of travel times and delays, congestion levels, and energy and emissions.
