Small-city traffic management using unmanned aerial vehicles (uavs)

Abstract

Dedicated Traffic Management Centres (TMCs) are only operational in three of the largest metropolitan areas in South Africa (in Gauteng, eThekwini and Cape Town). Smaller cities and towns do not have TMCs to assist with traffic management due to the prohibitive cost of these facilities. This research considers the benefits that a small city environment could gain from live traffic management, specifically considering the town of Stellenbosch in the Western Cape as a case study. Stellenbosch experiences heavy congestion during the morning and afternoon peak periods due to significant trip attractions. A framework for the implementation of UAVs to monitor traffic as part of TMC activities was determined for Stellenbosch. A case study includes determination of flight parameters; flight height and speed, as well as the path a could UAV follows to monitor traffic in a 4 km radius around its point of deployment. A framework for the implementation of UAVs to incident response is also created, indicating how UAVs could be used to aid emergency response personnel to better understand and respond to an incident scene. The cost benefit of using UAVs compared to traditional CCTV monitoring for traffic management was evaluated. Additionally, the benefits and limitations of such a system are identified according to findings from the case study. It was determined that using UAVs could provide substantial benefits for traffic monitoring in small city environments.
