CENTRO Bus Transit Message Center: Project Summary Background The Centro bus information system is currently running with the help of manual posters, flyers, online pdf files and images for the bus routes/timings and there is no database system which can be collaborated with a mobile application and can be made easily accessible to users. These flyers are freely available on the http://www.centro.org as well as at many public destinations such as Destiny USA (shopping mall), Wal-Mart and some community centers across the city. The traditional backend database system for this website is used by Centro organization is currently limited to its internal organization and its services. Whereas, the day to day commuters face a lot of problem in accessing the bus routes/timings, as the information is available only via pdf’s or on website. Also, users have to carry the Centro manual maps with them while travelling or in their phones in form of pdf’s. According to an online survey created by me at http://soorvey.com/en/?s=1C27KYLIRNQ, to which more than 70 users have responded, 76% of users rides a Centro bus more than 10 times a month. The survey results clearly displayed that only 9% users are currently satisfied with the information provided to them and 44% user demands improvement in the current system where 46% of users are not at all satisfied by the information services provided to them. Proposed Solution 1. User can create its profile by signing up and entering its Identity details, Living area, details. User can search for the bus routes and timings. 2. User can add his day to day schedule routes by entering the Source, destination, boarding time, reaching time, day, and month. 3. User can just enter the destination details and system will automatically pick up his location and will give him details about the nearest stop name along with the best suitable bus timings. 4. The database system will take input of the user preferences such as travelled routes, bus stops. Centro services will send the email/ text messages according to the users need. 5. The system will track the real time information according to the user’s geographical location and is not only dependent on the data entered by the user. It will be helpful as most of the times the university students have to take an unplanned bus, because of varying course schedules and group activities and seminars. The system should be integrated with each bus stop geographical location in order to enhance the transport experience. 6. The system will suggest the user about the best available route for his destination. 7. Current system will provide information about the delay in the bus schedule. Integration of the traffic, weather, special events and other uncontrollable circumstances.

The system will pick up user’s geographical location using his GPS (In this case manual data is used). Then system will use the user’s location to find out the nearest bus stop for that user. System is using the displacement theorem where each bus stop from database is compared against the user’s location and the smallest value is returned. Dummy User Data: User1: Location -> (1700, 700), Time = 1000 Hrs. User2: Location -> (800, 1200), Time = 2200 Hrs. User3: Location -> (3000, 400), Time = 1450 Hrs. User4: Location -> (3200, 200), Time = 1110 Hrs. Calculation of Nearest Bus Stop for User1 at (1700, 700): Distance from Centro Transit Hub = User 1 (1700, 700) and Centro Transit Hub (200, 1440) = > = 1672.6028 Similarly finding the distance from other bus stops as well: Distance from Centro Transit Hub(200,1440) 1672.6028 Distance from Forman Ave (1480, 1440) 772 Distance from Irving Ave (1480, 960) 340 Distance from University Place (1800, 960) 278 (Lowest) Distance from Ernie Davis (2120, 960) 493.96 Distance from College Place (2120, 480) 474.13 Distance from Ostrom Ave (2120, 320) 566.39 Distance from Sumner Ave (2760, 320) 1126.05 Distance from Westcott Street (3400, 320) 1741.95 Business Rules: 1. User can Start or Stop the bus service if he wants. Also the initial status of a message service is ‘active’ for all users. 2. User can see a maximum of 3 best suitable bus timings according to the location entered by him/her. 3. A user can have only one User ID corresponding to an email address. 4. A user can be issues more than one Bus pass.

A bus is supposed to run only on a single route and may be in both the directions. Major Data Questions: Who will send a Query? 1. Any user with a bus card can use the mobile application. The user has to input only the destination where user wants to go. The system will calculate the time, and his geographical location. 2. Admin can ask the system to send the message to a particular user and the system will automatically send out the message whenever a user requests a bus details. What Queries can be sent to the system? 1. User can ask the system to fetch the details of latest bus from his nearest stop by only entering his destination. 2. The system will check the user’s current geographical location and then finds out the nearest bus stop for the user. 3. The system will find out the most recent bus from that bus stop to the user’s defined destination. 4. User can ask the admin to start and stop a bus messaging service. 5. User can query the system to fetch out the details of a favorite bus stop added by him and then can ask for the buses timing from that bus stop. 6. User can check the balance on his bus card and the last recharge amount. 7. User can enter the bus route number and system will fetch the all route details along with the bus stops with the stop timings on that route. 8. User can check the details of a particular bus. The system will fetch the driver name, Bus capacity and its route direction. 9. A user can fetch all the details of a particular route. The system will fetch the Route Name, route direction, and the bus number going on that route. 10. The system will fetch the start time and end time of a route along with the start stop and the end stop. 11. The admin can manage the messaging system and can ask the system to send out the messages to the user for user’s destination. The system will send the message title, the text of the message and the sender’s details along with the time stamp. 12. The user can login into the system and check for all the messages he has received till date along with the receiving time, sender’s details and the message text.
