Osrm-backend: I Want to make changes in routing algorithm

[rachha]

Hello, I'm new to OSRM and open source projects. CH or MLD giving optimal time travel path. I want to calculate optimal Fuel Path.

1. So now I want to change the edge weights(time to fuel). Which part of the code I need to focus on.
2. For calculating Fuel consumption for each edge, I need to use elevation along the road. So which api I need to use. Please Help me.

Thanks

OSRM profiles will help you. You may need to write your own profile to represent weight for Fuel.

And feed elevation to the profile using SRTM data.

@wangyoucao577 is there any Documentation to understand profiles code wholly and accurately.
Thanks

@vinayrachapalli I wrote some docs for this recently, hope they can help you. FYI.

• Interaction Between C++ and Lua In OSRM
• How OSRM Calculate Weight and Duration
