Thank you for that, found it and it works a treat. One more
question for you: would OSRM benefit speed wise if it ran on a
GPU?<br class="">

<div class=""> If you look inside the "route_summary" member of
the JSON response, you'll find both the "total_time" and
"total_distance" sub members, which sound like the values you
want. The new example shows how to easily access these.</div>

I'm building some code based heavily around the
"simpleclient.cpp" example in the tools section of the
source code. I'm trying to simply extract the driving
distance and time from the returned JSON object. <br class="">
<br class="">
This could be achieved by taking the object returned and
manipulating it which seems wasteful, or I could amend
the code such that is purely returned the required
information. If the latter isn't realistic, then using
the existing JSON handler, how could I extract
information from the JSON object?<br class="">
