Why do I see different toll rates when using the TollGuru API – Origin, Destination, and Waypoint, compared to the Web Calculator and Complete Route Polyline from a Mapping Service?
Last updated on Apr 21, 2025 · 2 minutes
Differences in toll rates can occur between the TollGuru API, Web Calculator, and Complete Route Polyline from a Mapping Service for the following reasons:
1. Dynamic Routing
Both the TollGuru API and the Web Calculator use real-time routing data, which means the routes may change based on traffic, road closures, or construction.
2. Vehicle Type Differences
For 2AxlesAuto (passenger vehicles) and 2AxlesTruck (trucks), toll rates will differ due to vehicle-specifics like axles, height and weight.
3. Different Mapping Service Providers
The TollGuru Web Calculator and the API may use different mapping service providers. These providers use different algorithms and routing data, which can result in different routes and toll rates.
4. Toll Rates for the Complete Route Polyline from a Mapping Service
When using the Complete Route Polyline from a Mapping Service endpoint, the polyline from another mapping provider might travel different roads than those calculated by the TollGuru API, leading to different toll rates. Different providers use different algorithms, which could result in varying toll roads being included in the route.
