DEVELOPMENT OF A COMPUTERIZED MOVING VEHICLE SIZING SYSTEM USING IMAGING TECHNOLOGY

In 1995, International Road Dynamics Inc. (IRD) was contracted by the Transportation Development Centre to develop and test a computerized system to measure speeds and dimensions of moving vehicles using video imaging technology, and to demonstrate its application and integration with the existing Heavy Vehicle Electronic Licence Plate (HELP) Project. Such a system would be a tremendous asset for traffic engineering, highway planning and tracking of vehicles in critical situations. Different technologies which could be used for measuring speeds and dimensions of moving vehicles were identified and investigated. Each of these technologies was further evaluated for possible development into a vehicle dimensioning system. The initial results showed that systems employing laser and microwave technologies are not sufficiently price-competitive but devices employing video imaging technology hold great promise. Subsequent investigation into video imaging technology formed the basis for the V-DIM (Video Dimension-In-Motion) system development. Two complete engineering prototypes of the V-DIM system were developed and field tested. Test results showed consistent width and speed measurements of moving vehicles. The V-DIM system has indicated good performance in the areas of presence detection, speed detection and width measurement, with the potential for effective length measurement. It provides functionality and capabilities beyond those achievable with other existing technologies at comparable prices. The V-DIM system is definitely an important step in applying technology to develop new solutions to traffic management problems. (A)
