An In-Vehicle Embedded System for Intelligent Transport System: Modeling and Simulation

Abstract

Computers & communications are becoming integral part of intelligent transport systems. Such system aims to provide better amenity for passengers, vehicle condition monitoring, driver performance and vehicle fleet management. The thesis discusses the development of such a system using modern embedded system design approach.

Embedded system described here automates all functionalities including the timing information, ticketing process; station information, passenger information etc., which are packaged with minimal manual entry required by bus-driver. Development cycle of an embedded system includes modeling as the foremost step. Modeling is the process which reduces the development time and also helps in testing the system before manufacturing. That way modeling reduces market window of an embedded system by great amount. For modeling Ptolemy 6.0.2, which is open source tool from Berkeley University is used.

All the functions are understood and defined with separate modules, and models have been developed that simulates the functionality. The Ptolemy tool refers each individual entity as an actor that operates on tokens. During project some actors in original tool have been modified and found more efficient later. Also some actors’ are developed, patched and then used for this project. Simulation needed cross compilation of the generated code for specific target system and then checking its performance.

Different modules have been implemented to develop entire design. System statecharts, model design and working of modules are included. After implementation of individual units, they have been integrated. Core Java and Cygwin were used for adding actors and code generation.
