Automated Toll Fare Calculation

1 post · Jul 2019

What this trail covers

Grab has evolved its fare calculation system to automatically incorporate Electronic Road Pricing (ERP) charges and other tolls across various countries. This involves collecting precise geographical coordinates of toll gantries, understanding country-specific tolling rules (e.g., different rates for vehicle types, couple gantries), and implementing a dynamic fare calculation mechanism. A feedback loop with driver-partners and an ERP Workflow tool are in place to ensure data accuracy and handle ad-hoc changes.

  1. No More Forgetting to Input ERP Charges - Hello Automated ERP!This post details the technical approach to automating ERP fare calculation, including data collection strategies for geographical coordinates and toll charges across multiple countries (Singapore, Malaysia, Indonesia, Thailand, Vietnam). It highlights the importance of location precision, the use of driver GPS pings to identify gantry passage, and the development of an ERP Workflow tool for Ops to verify driver feedback by mapping ride trajectories with gantry data. The system is designed to handle dynamic toll statuses and country-specific rules like couple gantries and varying charges for vehicle types.
