A MICROWAVE BASED DATA-COMMUNICATIONS SYSTEM FOR TRAFFIC MONITORING ---TRAFFIC MANAGEMENT AND ROAD SAFETY. PROCEEDINGS OF SEMINAR D HELD AT THE PTRC TRANSPORT AND PLANNING SUMMER ANNUAL MEETING, UNIVERSITY OF BATH, ENGLAND 7-11 SEPTEMBER 1987. VOLUME P291

The transport operations research group at newcastle university and the school of electronic engineering at newcastle polytechnic are collaborating on a development project aimed at testing a prototype data-communication system for automatic traffic monitoring. In recent years it has been recognised that a form of robust, cheap and reliable data-communication between a roadside unit and a moving vehicle is desirable. Considerable development has taken place in the fields of information technology, data processing and communication systems which has resulted in a number of prototype automatic data-communication system being developed using infra-red beam, satellite, radio and inductive-loop technologies. A low energy microwave system currently under development on a serc-financed project at newcastle offers improved performance over the above systems due to the small size, low cost and high data-transfer rates achieved. Following a brief review of the background and applications of the system, the proposed paper will discuss the design and development of a low profile microwave receiver. The low profile structure is realised using microstrip technology which uses photo-etching techniques as used in the manufacture of printed circuit boards. The associated digital sub-system consisting of a microprocessor and support devices will be implemented using vlsi to achieve a low profile design compatible with the microstrip receiver. Experimental results relating to the overall performance of the system obtained from field trials will be given in the paper. The receiver system will be developed finally in a form similar in size to the conventional tax-disc and approximately 5 mm thick, which will make it suitable for mounting on the windscreen of a vehicle. The system could have numerous applications, such as: collection of data on traffic parameters, automatic vehicle identification, fleet control, automatic toll-collection at bridges, tunnels and car parks and route guidance/traffic information systems.(a) for the covering abstract of the seminar see IRRD 816514.
