Survey on Traffic Control using Closed Circuit Television (CCTV)

摘要

As the problem of overpopulation worsens, traffic control becomes a grand challenge. Among the main technologies used to implement solutions for this challenge is the Closed Circuit Television (CCTV). CCTV systems are increasingly being deployed across city centres, motorways, trunk roads, car parks etc., to collect diverse data on large regions where manual observation can be difficult, problematic or unfeasible. By processing this data, which contains video images of traffic parameters, useful information can be extracted, including speed, traffic composition, vehicle shapes, vehicle types, vehicle identification numbers and occurrences of traffic violations or road accidents. This paper reviews state-of-the-art CCTV systems used for traffic control applications. It highlights existing architectural and deployment models, as well as the various approaches utilised to analyse generated traffic data, providing examples of prominent work on each approach. The objective is to provide a clear background that can help in any related future research.
