AIMED AT tracing the movement of buses introduced by Indore City Transport Services Limited (ICTSL), Global Positioning Satellite/System (GPS) will have two components - the mobile unit and the control room.
The mobile unit to be installed in every ICTSL-run bus will have a GPS antenna and a palm-sized modem. The modem with a GSM sim will be installed near the dashboard and the antennae on the bus top. The antenna will emit continuous signals about the location of the bus through a constellation of 24 satellites launched in space by US Department of Defence in 2000.
After collecting the signals, the vehicle unit will transmit it to the control room at ICTSL head office on AB Road. “The information from vehicle unit to the control room will be sent by Global System for Mobile Communication,” informed K B Yermalkar from Arya Omnitalk Wireless Solutions Private, the Pune-based company installing GPS for the City buses.
The control room function will, however, be complex compared to the two-device mechanism of mobile unit. It will have four servers catering to different needs. The communication server will keep tabs on every movement of each bus by collecting all their position data.
Automatic Vehicle Locator System server will generate a detail map of Indore through Geographic Information System. The server will give position of every bus on the map along with speed of vehicle, over speeding if any, its stoppage time et al.
Public Information System server will keep track of information pertaining to all bus routes, bus numbers and advertisements to be exhibited on PIS text display, the Light Emitting Diode (LED) to be installed at every bus stop. The server will calculate the time a bus would take to reach the next bus stop and display on the LED screen of the particular bus stop.
LED screen would display the bus number, schedule and estimated time of arrival. The Management Information System (MIS) server will compile everyday bus-wise and bus stop-wise report. It will generate a monthly report for ICTSL Executive Director and District Collector Vivek Aggarwal.
Arya Omnitalk will hand over the GPS to ICTSL after operating it for five years. The GPS installation, which will be complete by this month-end, will cost Rs 60 lakh and is based on Build, Operate, Own and Transfer (BOOT) system.
LED display system is being used for the first time in the country for a public transport system and will function on wireless technology. “Although it is used at railway stations and airports in the country, they all function on wired technology,” Manoj Varghese from Arya Omitalk said.
GPS use elsewhere
Bank vans carrying cash, emergency response services like hospital buses and police wireless sets use Global Positioning Satellite/System (GPS) in the country to keep track of their vehicles.
Bangalore Municipal Transport Corporation and Gujarat State Road Transport Corporation have also deployed it in addition to call centres of Delhi and Mumbai for their employee transportation vehicles. The GPS control rooms for cash vans are equipped with additional accessories to ensure safety of currency that banks transport from one place to another.
These control rooms can stop fuel supply to the engine, switch on sirens and even shut doors of vans. The control room can also regulate the temperature inside vehicles. Drug manufacturers and serum research institutes mostly use these temperature-monitoring vehicles to avoid harm to medicines during transportation.
