Abstract

Detail

A railway traffic controller system takes care of assigning railway platforms for incoming and departing trains in a railway station. In this project we plan to automate the task of assigning railway platforms to trains depending on their direction of commute and availability of platforms. The loco-pilot inputs the direction of travel, the system calculates the suitable railway platform (out of four available) and informs the loco-pilot which platform to park, or wait until the platforms are available

Working

Detail

Explain the working of your model with the help of a functional table (compulsory) followed by the flowchart. Input and Output Description: The input will be a 2-bit integer out of which 1bits represent the type of the incoming train and the remaining bits represents the direction of incoming train . Passenger train can come and park. The system will store the information regarding the previous train which has come to the station and updates the track availability for the next coming train. We are considering two types of trains, that is : passenger train or goods train and there are limitations on which passenger train can park that is passenger train can park only on 1st and 4th platform. The output will be a 5-bit integer value which tells the loco-pilot to either park the train or halt it which is considered an invalid case. If the parking signal is given to the pilot, the four bits would represent situation of railway track after train has parked if at all train is parked. If the halt signal or the invalid signal is given, after the waiting time, input is requested again.

The motivation behind a railway traffic management system project include: Safety Enhancement: Improving the safety of railway operations by implementing advanced control andmonitoring systems to prevent accidents and incidents.

Efficiency and Reliability: Enhancing the efficiency of railway services by reducing delays, optimizing schedules, and ensuring reliable transportation for passengers and cargo
