Hi Sriram
to reply a part of your question:
take a look at this documentacion [1]
The first number is driving directions.
The geomerty is a compressed tring that you have to decompress.
also discripted in the Link below.
Kind regards
Carsten

Betreff: [OSRM-talk] Plotting position in time using OSRM
I would like to create a simple simulation of a trip using OSRM.
I believe the steps would be as follows (my questions are in parenthesis below)
a. Load OSM map of a city into OSRM
b. Choose a random begin, end location that falls within the city lat/long (how to find lat/long limits of the loaded map?)
c. Compute the distance (in time) between start, end using OSRM
d. Also compute a path between start, end using OSRM (are the node vertices mentioned in route the same as in the OSM map?)
e. The difficult part:
-- start the simulation by displaying the map along with position marker (Leaflet?)
-- As time progresses, determine the location along the OSRM route computed above (how can this be done?)
and adjust the position marker.
An OSRM route looks like this:
"route_instructions": [ [ "10", <-------------------- what is this id and how to convert it to lat/long "Schulstraße", 126, 0, 18, "126m", "SE", 116 ], [ "7", <---------------- how to find elapsed time to this point from previous one "Am Rahmtor", 57, 2, 11, "57m", "NE", 38 ]
Given a start and end lat/long, a network distance (time) can be obtained as follows: "distance_table": [ [ 0, 26084 ], [ 26084, 0 ] This would be useful if the route way-points above could be converted into time units.
Would appreciate any help with the above questions,
Sriram
