How eSafeRIDE Works

Built in Uganda Pilot-Ready Community-Driven

Accessibility-Weighted Routing Engine

eSafeRIDE introduces a route optimization module implementing a modified Dijkstra's algorithm. This spatial algorithm is explicitly parameterized for complex campus topography and severe physical impairments, processing real-time location telemetry to calculate optimal paths that actively avoid unpaved terrain and staircases.

How the Algorithm Works

1

Real-Time Location Telemetry

Processes GPS coordinates from both the student app and accredited vehicle fleet to establish current positions within the campus geofence.

2

Topographical Data Processing

Analyzes spatial data including terrain type, slope angles, staircase locations, and ramp accessibility points across the campus environment.

3

Modified Dijkstra's Algorithm

Calculates optimal paths that actively avoid unpaved terrain and staircases, prioritizing ramp-accessible drop-off zones for a mixed fleet.

4

Dynamic Route Optimization

Continuously updates routes based on real-time conditions, vehicle availability, and accessibility constraints to ensure the safest, most efficient journey.
