Compact matrix calculation

Basic principles

This web service calculates a route matrix for a series of points and returns a distance matrix. The distance and time computations are based on the actual road network.

(Hazardous material)

See description bellow.

4.

What are the Hazardous material exclusions?

Hazardous material defines a restriction to a road for any vehicle carrying the specific hazardous material. Hazardous material restrictions are government regulations and can be different per country.

  • Flammable: explosives, flammable, gas, combustible, …
  • Pollutant: goods harmful for water
  • Toxic: organic, poison, radioactive, corrosive, …
  • Dangerous: tunnel categories and others restrictions

5.

What are Speed Patterns? How are they used?

With the aim of suggesting journey times that take traffic conditions into account as accurately as possible, cars and trucks have 5 speed profiles (Speed Patterns) so various levels of road congestion can be taken into account over the timespan of a whole day:

  • standard normal-speed corresponds to the speed at a time when the traffic congestion is moderate (11h)
  • night fast-speed corresponds to very fluid traffic conditions, most often found at night time (3h)
  • busy slow-speed corresponds to the times when traffic congestion is at its densest (8h)
  • peak travel time very-slow-speed corresponds to times when traffic is densest in urban areas, and is slower than the category given above (8h)
  • default default corresponds to average speeds over a whole day

To use these, you will need to pass to parameter, when calling the web service, the following parameter computeOptions with the option speedPattern and specify the value of the Speed Pattern requested, always remembering to include a vehicle configName.
Example:

&computeOptions=speedPattern:fast-speed&configName=car

6.

How do you use heavy goods vehicle attributes?

You need to calculate an itinerary using either a vehicle configName using the restrictions, or by overwriting the call to the web service using the parameter computeOptions with the options length, width, height, weight, axles and/or weightPerAxle.
Example for a journey with a vehicle with a height of 4.5m:

&computeOptions=height:450
