Vehicle Identification in Mega City – A Success Story

Vehicle Identification in Mega City – A Success Story

A new dimension in vehicle tracking has been achieved in Bangladesh through an innovative electronic system to identify and monitor vehicles.  Tracking and identifying the massive number of vehicles in large Bangladeshi cities is a major issue for highway authorities to manage traffic control, react to accidents, maintain security, manage tolls and minimize congestion.

The Bangladesh Road Transport Authority intended to get an automatic identification of vehicles in Dhaka metropolitan area to monitor the massive number of registered vehicles entering and exiting the city day and night. Implementation of such systems with massive installation of devices and communication system is a complex task. The blending of the essence of proximity tags in vehicles, installing computer based readers in diverse locations and connecting them together became very challenging.

Omni-ID has redefined and customized the Exo 800 Passive Tag to become a Storage Tag to enable the EVI System to mitigate that challenge. This customized tag can have a limited amount of information that can be stored once and used in a read-only manner. Radio waves are the key component of these proximity tags that are powered by radio frequency signals from the reader device in a limited range.

Features of the customized Exo 800 Tags:

 

Store a limited amount of data.

Tags work in read-only mode.

Works in limited read range.

 

The EVI system of BRTA have deployed these tags as a proximity storage device, primarily to be used with computers (handheld devices), where there is no internet connection.  Several hundred deployed handheld computers verify the vehicles at remote locations. The customized Exo 800 device stores the vehicle information in compressed form that can then be read by authorized handheld computers providing the necessary data of traffic volumes and flows etc.
