Some insights

When making roads, the government doesn't always pay the contractors in full. Instead the government lets the contractors charge a toll from the road users for a particular timeperiod. The toll values are fixed by the government (revised each year). A contractor might have contracts of more than one stretch of road, and hence more than one toll checkposts. A toll checkpost can have multiple toll booths. Each toll booth needs to be configured before it can be used. Since each toll booth uses a camera, the system needs to be told about it. Once the camera has been configured, the system needs information about the toll checkpost so that all the transactions can be linked to it. The toll booth's job is to identify the vehicle using the camera and begin the transaction generation process.

Each transaction should contain enough information to uniquely identify the toll checkpost, the contractor and the vehicle owner. Once the transaction has been created, both parties are informed about it. To avoid misuse, the vehicles have to be registered into the system. Incase of an unregistered vehicle, the system will not allow the vehicle to pass and will also notify authorities. Using this system, the contractor and the authorities can monitor all the toll checkposts. The vehicle owners can monitor their expenses and vehicles. This project has been designed as a realtime system.

Booth client

  • Login using admin credentials
  • Create a booth configuration (Select camera)
  • Select a toll to add the configured booth to. Run the RC plate detection bot and send HTTP requests to the Pass Cloud function.

Pass cloud function

  • Args: vehicleRc, checkpostId, timestamp

  • if request authenticated and args valid

    • create a pass event
    • if the vehicle is normal or exempted
      • create the transaction event
    • else
      • create the blacklisted vehicle event
    • return

  • else

    • if authorization error
      • create unauthorized request event
    • if validation error
      • create bad request event
    • if any other error
      • create unknown error event

  • Send notifications to users on successful transacion creation

The Process:

Creating a transaction

  1. A bot reads the RC number from video feed and sends a request to create apt transaction.
  2. The server-side then checks the vehicles database for existing records matching the rc provided by the bot. It also checks the booths data base for existing records matching boothId provided by the bot.
  3. On successful match, the server creates a transaction between the booth and the vehicle owner. The server sends the payment link to the user. The server then responds to the bot with the transactionId.
  • Whenever a new vehicle passes, the vehicle details are displayed on the screen. If the vehicle is blacklisted, the booth boom will close. The admin can then choose how to handle the case.

Accepting payment

  1. The user goes to the payment page and enters credentials. (Click on pay button).
  2. The server then updates the transaction status as complete.

Generating receipts

  1. The user clicks on generate receipt.
  2. The server sends a JSON file with transaction details.

Reporting suspicious activity

  1. The user receives a notification about a pending transaction.
  2. The user then selects report suspicious activity.
  3. The server then updates the vehicle status as blacklisted.
