Installation

Install the library from npm:

npm install @maptrip/truck-tolls-germany

Usage

To fetch the toll rate, you need values for the CO2 Class, Axle & Weight Class, and Euro Class of the truck. These values are provided using TypeScript enums and can be imported from the package.

Enums and their values:

enum CO2Class {
    One = 1,
    Two,
    Three,
    Four
}

enum AxleWeightClass {
    Over_3_5_Tons = "3,5-7,49",
    Over_7_5_Tons = "7,5-11,99",
    Over_12_Tons = "12-18",
    Over_18_Tons_3_Axles = "18&3",
    Over_18_Tons_4_Axles = "18&4",
    Over_18_Tons_5_Axles = "18&5",
}

enum EuroClass {
    Euro1AndZero = "euro1AndZero",
    Euro2 = "euro2",
    Euro3 = "euro3",
    Euro4 = "euro4",
    Euro5_EEV = "euro5_EEVClass1",
    Euro6 = "euro6",
}

Fetching Toll Rates

The TollRateProvider has one method getTollRate, which requires a value for each above enums. This method returns the toll rate in cents per kilometer (cent/km). You can use this rate in combination with the total kilometers of toll roads along a route to calculate the total toll cost.

import {
  AxleWeightClass,
  CO2Class,
  EuroClass,
  TollRateProvider,
} from "@maptrip/truck-tolls-germany";

const tollRateProvider = new TollRateProvider();

const truckOneTollRate = tollRateProvider.getTollRate(CO2Class.One, AxleWeightClass.Over_18_Tons_3_Axles, EuroClass.Euro6)

// returns number 30.3
// multiply this with your total toll roads length to get the total toll cost

Example with MapTrip Server API

To get the total kilometers of toll roads along a route, use the MapTrip API /route endpoint. The value is returned in meters.

As of the first published version of this package, 1.0.0, the provider parameter for the /route endpoint must be either provider=HERE or provider=TomTom. OpenStreetMap does not provide toll information for routes within Germany. OSM German toll data is planned for integration into the MapTrip Server API for a future release.

function getTollsFromRoute(start, destination, token){
  //Use HERE or TomTom for the provider to get tolls in Germany. 
    const url = `https://api.maptrip.de/v1/route?provider=HERE&from=${encodeURIComponent(
      start
    )}&to=${encodeURIComponent(start)}&vehicle=truck`;

    try {
        const response = await fetch(url, {
            headers: {
                Accept: "application/json",
                Authorization: token  //MapTrip token
            },
        });
        const data = await response.json()

        // Return the toll data in km 
        const tollRoadLengthInKm = (data[0].summary.toll / 1000).toFixed()
        return tollRoadLengthInKm
    } catch (error) {
      console.error("Error fetching data", error);
      throw error;
    }
}

async function calculateTotalTollCosts(cO2Class, axleWeightClass, euroClass, start, destination, token){
  try {
    const tollsInKm = await getTollsFromRoute(start, destination, token);
    const tollRateProvider = new TollRateProvider();
    const tollRate = tollRateProvider.getTollRate(cO2Class, axleWeightClass, euroClass);

    // divide by 100 to get a total in euros rather than cents
    const totalInEuro = ((tollsInKm * tollRate) / 100).toFixed();
  } catch (error) {
    console.error("Error calculating total toll costs", error);
    throw error;
  }

}
