– Closing/ opening of door
5. USE OF THE VTU
DRAFT – not for circulation
• Journey management
– Route deviation
– Early arrival/ late departure
– Schedule trip status
– Excessively long stoppages
6. USE OF THE VTU
DRAFT – not for circulation
• HSSE (Health, Safety, Security and Environment)
– It can be used to check the health of the vehicle as
the system can intimate required servicing after it
reaches a benchmark
– Safety & security is ensured as the vehicle can be
tracked all the time
– It also helps reduce wastage of fuel as the trips could
be planned more optimally.
– The locational information could feed the Passengers
through the Passenger Information System (PIS) and
help increase ridership. In turn it could result in
people shifting from private vehicles to public
transportation.
Vehicle tracking units (VTU) are extremely important to optimize resources for organisations operating large fleets of vehicles and if there is need to constantly monitor vehicle for security reasons. A combination of both active and passive VTU is most preferable as the passive system stores GPS location, speed information etc if the cellular network is not available and relays it when the vehicle comes in the range of a network. An active VTU consists of the following 2 devices:
Global Positioning system (GPS) which provides the exact latitude and longitudinal position of the vehicle as relayed by the GPS satellite.
General packet Radio Services (GPRS) is a mobile sim that sends packet oriented mobile data relaying the vehicle position to a central repository.
The data collected from this transit vehicle following its route could be continuously fed into a computer program which can predict the arrival of the vehicle at different locations in that route.
GPS tracking device- Apart from the locational information the device can capture other vehicle related information as well.
GPS tracking server- this receives data, securely stores information and serves it on demand to its users. It should ideally be a cloud based system so that people in different locations could access the information.
User interface is the dashboard that determines the way in which the information is represented (as an attribute or map form), view the vehicle data and other details.
(In BMTC the control centre will get an alert if the driver has stopped the vehicle longer than 5 minutes in course of the journey)
