Our latest contribution to the open routing machine OSRM

OSRM: arrive on the right lane (right-hand traffic)

Mapotempo solutions are based on free components. For instance, for Mapotempo Web and the Routing API we use the open source routing machine OSRM.

About OSRM

The open source routing machine OSRM use OpenStreetMap’s data.

Our development team has made a new contribution to the free OSRM project. You can find the source code of this contribution here: github.com/Project-OSRM/

Arrive on the right lane :

This option makes it possible to compute a route that makes the vehicle arrive on the right road lane.

When the vehicle is traveling on the right-hand side of the road and its arrival is on the left-hand side of the road, the vehicle will not stop on the right-hand side next to the arrival. The route computation will make the vehicle take a route that will allow it to arrive in the right direction, left-hand side, so that its end point to be on its right-hand, even if it has to make a detour.

This allows vehicle’s passengers to get in or get out of the vehicle without having to cross the road by foot.

Examples 1


The end point (red) is on the right-hand. A direct route is calculated because the vehicle is already on the right side of the road.



The end point (red) is on the left-hand. The route makes a turn around through the roundabout so that the end point is on the right-hand of the vehicle.

Examples 2


If the end point (red) is on the left-hand but the street is one-way, the computed route will simply stop at the end point.

This feature is particularly useful for buses, taxis or garbage pick-up, services for which the regulation imposes the security of users and operators who do not have to cross the roadway by foot.

A feature that will be integrated into the next version of Mapotempo Web and the Routing API

After having contributed to the OSRM routing machine, our development team is now working on new features.

Mapotempo is a French startup that develops intuitive and innovative route planning and route optimization solutions.
