Development of Controller For Internet of Things Based Anti Pollution Smart Toll Gate System

The transaction system applied onto the current toll gate system is less effective in overcoming the queue of vehicles, especially during public holidays or long holidays. Although it is already based on contactless technology, but toll road users still need to juxtapose the e-Toll card manually for four seconds. This is in time causing the queue and density in several toll gates. To alleviate this problem, the toll provider cooperates with bank to issue the e-toll system On Board Unit. This device can strengthen the e-Toll card signal to make reading distance farther. However, it is not popular in the community due to the price. This paper deals with the hardware and software development of controller for IoT based Anti-Pollution Smart Toll Gate system which has lower production costs. Two testing scenarios have been conducted. Ultrasonic sensor reading distance testing shows that the effective distance is approximately 300 cm. Testing the system response to vehicle speed shows that the system is able to work well with vehicle speed up to 20 km/h.
