Jan 31, 2017: Some trajectories are missing from the repository.

Benchmark trajectories for Joint Map Matching for Large Scale GPS Trajectories by Y. Li, M. Kerber, L. Zhang and L. Guibas. In proceeding of ACM Sigspatial GIS 2013.

Manual map matching is done using trajectoryTracerDemo

Directory list

  • manual_matched : contains dense trajectories (.coor.txt) and their corresponding path on the road network (.txt)
  • sparse_trajectories : contains sparse trajectories (.coor.txt)
  • map : road network and osm files

Trajectory format

For files with suffix *.coor.txt

<#_of_trajectories>
<trajectory_id> <car_id> <#_of_points>
<timestamp> <x> <y>
...
<trajectory_id> <car_id> <#_of_points>
<timestamp> <x> <y>
...

Note: values in trajectory_id, car_id and timestamp may be placeholders

Path format

For files with suffix *.txt

Each row represents a path

<edge_id1> <edge_id2> ...

edge_id references to edges in map/adjacentList.txt
