PLATFORM ASSIGNMENT SYSTEM FOR THE TRAINS IN A RAILWAY STATION

1.PROBLEM STATEMENT:This project is about platform assignment system for the train in a railway station. It

contains 3 modules. The first module gets the current time, scheduled time of the train, expected time to enter the station, departure time and platform no to calculate the time delay of the train. If the time delay is more than the specified time also if arrival time and platform no of next train gets clashed then next train cannot be allocated in the same platform.

2.OVERALL DESCRIPTION:2.1 MODULES:

Login Train details Delay calculation Platform assignment

2.2 MODULE DELIVERABLES:Login:Basicflow:To authenticate the user,the admin has to enter username and passwordAlternateflow:If the password is wrong, it will ask the admin to answer security question and retrieve the passwordPrecondition:The system asks the admin to enter the passwordPostcondition:On success,the admin displays the admin informationTrain Details:Basicflow: The train details like train no, scheduled time, expected time to arrive, scheduled time for departure, expected time to start, platform number and current number is given as input to calculate the time delay. Alternateflow: If the train details is not correct admin can report it.Precondition: The train details should be known.Postcondition: After verifying all the details, admin is moved to the next state.Delay calculation:Basicflow:The entered details are verified with the database and time delay is calculated and also checks whether there is any clash with the next train timingAlternateflow:If the details are incorrect, error message is generated.Precondition:The details of the database should be up to date.Postcondition:After verification the platform assignment is done.Platform Assignment:Basicflow:Based on the delay and arrival of the next train the platform assignment is done.Alternateflow:If no platform is free then the train is made to wait.Precondition:The availability of the platform should be known.Postcondition: The platform is confirmed and the signal is given for the train to stop.
