There are certain types of road users, such as pedestrians that are either difficult to detect or cannot be detected by conventional underground loop detectors. This paper outlines alternative methods used to detect road users and shows some of the successes and problems encountered along the way. Transport SA is frequently asked to provide greater time for disabled and or elderly pedestrians at Pedestrian Actuated Crossings situated near Schools or retirement complexes whilst at the same time being asked to provide assistance to public transport, freight routes and general vehicular traffic along the same corridors. In order to accomplish this task, the use of microwave and video as ways of detecting these road users were investigated. Comparisons are made of the traffic volumes collected using video and loop technologies to detect vehicular traffic.
