Questions about map matching #6844

I use the map matching service to match the coordinates of the GPS to match and correct it. The matching service played a role in this process, but it is not complete

Because the accuracy of the GPS device is not high, when drawing the GPS coordinate point on the map, it often falls on the wrong lane, so the Map Match service of OSRM is used, but the effect cannot be satisfied.

How can I make the vehicle trajectory finally on the same road. I checked the relevant wiki and parameter descriptions. There is no request to pass the driving direction parameters. Is there no enough parameter to support OSRM for accurate judgment? WX20240410-163121@2x
