| Abstract: | Based on the proposed travel time estimation model and method by using taxi-based global positioning system(GPS),the key issues of the traffic simulation system on the basis of geographic information system(GIS) are studied.The indicators are first presented to appraise the simulation system,including information accuracy,information betimes,information universality and information cost.The establishment of road network connectivity topology is then discussed;the transformation model between GPS coordinates and city plane rectangular corrdinates is further derived,and the implementation of the simulation model is therefore illustrated.Through the simulation experiments based on the system,the model and method are tested,which proves they are feasible and effective. |
| Keywords: | traffic simulation connectivity topology coordinate transformation global positioning system geographic information system |
