M2M Architecture for Enhancing the Public Transportation Management Services Using ARM7

The project aims in designing a system which is capable of predicting the bus travel time and sending the travel time to the user on his request. The system makes use of GSM modem and GPS receiver along with Microcontrollers to achieve the task. Travel time information is a vital component of many intelligent transportation systems (ITS) applications. In this proposed system we introduced advanced public transportation systems (APTS) for public service. Advanced public transportation systems (APTS) are one of the most important applications, which can significantly improve the traffic situation in India. One such application will be to provide accurate information about bus arrivals to passengers, leading to reduced waiting times at bus stops. This needs a real-time data collection technique, a quick and reliable prediction technique to calculate the expected travel time based on real-time data and informing the passengers regarding the same. The scope of this proposed system is to use global positioning system data collected from public transportation buses plying on urban roadways, India, to predict travel times. The performance of the proposed system is found to be promising and expected to be valuable in the development of advanced public transportation systems (APTS) in India. The work presented here is one of the first attempts at real-time short-term prediction of travel time in Indian traffic conditions. The controlling devices of the whole system are Microcontrollers. The project makes use of two Microcontroller based systems, one in the bus and other at bus depot. The user needs to send his source and destination in the predefined SMS format to the bus depot number. The SMS will be received by GSM modem in bus depot and fed to Microcontroller. The Microcontroller sends an SMS through GSM modem to the system in bus with that source and destination. The system in the bus calculates the time required to reach the user location basing on the GPS data of current location and predefined user location data and sends this time information to the user mobile. This helps the people in saving the valuable time from waiting at bus stops. The Microcontrollers used in the project are programmed using Embedded C language. .
