Review of GPS-GSM Based Intelligent Speed Assistance Systems: Development and Research Opportunities

About two billion passenger cars travel the roads of the world and this is projected to double by the year 2050. This calls for the need to create real time surveillance systems to manage the impending dangers of on-road traffic and to meet the objective of intelligent transport systems (ITS). Nowadays, speed control and monitoring is mostly handled using speed law enforcement measures, such as speed bumps, speed limits, signs, speed guns, road designs, speed cameras and intelligent speed assistance (ISA). Previous surveys have not given enough attention to the application of Global Positioning System (GPS) combined with Global System for Mobile Communication (GSM) based ISA systems with respect to their types. To fill this gap, this review aims to study the different development and applications of GPS and GSM based ISA systems with the focus on their types, technology and analysis environment. Although, the development of ISA systems is not recent, the full potentials of using ISA systems are still a persistent pursuit. The study concludes by highlighting limitations and research opportunities mined from the reviewed papers to enable improvements and novel researches from the ITS research community and vehicle manufacturers' companies.
