[OSRM-talk] Customized Route Planning using OSRM

[Nida Fathima]

Hi Daniel,

Firstly, thank you for your quick response and I apologize for my late
reply.

Your input on the speed-up graphs and the suggestion to use A* algorithm is
valuable for me. I will start my work on it.

Thank you once again.

Best Regards,
Nida
