A review of IoT devices for traffic management system

摘要

In recent times, traffic congestion has increased at a breakneck speed especially in metropolitan cities. Traffic congestion leads to increase in noise pollution, traveling time, pollution, and fuel wastage etc. There are short term and long term causes of traffic congestion. Short term causes include traffic signal failures, inefficient law enforcement, inadequate road infrastructure, accidents etc. Long term causes are attributed to economic growth of the society, changes in lifestyle of people etc. As a result, traffic management has become one of the vital areas to be looked into. It includes monitoring of traffic density, communication, rerouting of traffic to avoid further delay. Internet of things can help in smooth implementation of traffic management system. There are different methods of traffic management - video analysis, wireless sensor network, adaptive traffic control system that are closely knit around IoT devices.
