Review of algorithms for monitoring urban traffic in smart cities

Abstract

Urban traffic, as a complex socio technical system, is one of the most challenging issues for monitoring in urban environments. It becomes one of the main concerns in smart cities. Recently, urban traffic monitoring attracted both researchers from academia and practitioners from variety of technical and social sciences. Although several specific solutions have been proposed and implemented in the practice, there is a need to provide comprehensive literature reviews to reveal recent publishing trends, areas of research, and point out possible further research directions. This paper presents a literature review of algorithms for monitoring urban traffic in smart cities, based on the recommendations for conducting systematic literature reviews. The objectives of the presented literature review are to inquire which types of algorithms are used for monitoring urban traffic, and which segments of urban traffic are monitored. Results of the presented review contribute to the general knowledge base on urban traffic and can be used as starting point for further review studies on specific algorithms or areas in urban traffic. In addition, presented results can serve as a starting point in finding possible solutions to specific problems in practice.
