SRMSS: three model buses in a depot, surrounded by orange route threads strung between brass pins
01

The brief

Each depot manages its own drivers, vehicles, routes and schedules and must never see another depot's data. Scheduling also has to catch a driver or vehicle being booked twice before it happens.

02

What it does

  • 01Session authentication with role-based access control and depot-level data scoping in middleware
  • 02Depot, driver and vehicle management, including licence-expiry alerts
  • 03Route builder on Google Maps: places search, real-road directions and map-marked stops, with a Haversine fallback
  • 04Schedule conflict detection inside database transactions, separating blocking conflicts from advisory warnings
  • 05Fuel and maintenance logs
  • 06Depot dashboard with Chart.js and PDF reports generated with Puppeteer
  • 07bcrypt, helmet, CSRF protection, express-validator and parameterised SQL throughout
