Road network is an important element in the map.The surface roughness of a road is essential forevaluating its usability.It is associated with:Driving Safety,Passenger comfort,Damaging of the road.The integration of bicycle trajectory data andaccelerometer data can be a good method to get theoverall IRI of road.Bicycle-Mounted Smartphone method is a low cost，lowthreshold and a wider range of roughness acquisitionmethod.The bicycle trajectory data will help to deeply understandthe human dynamic distribution，mobility, and livingbehaviors.
