The requirement for data model in microscopic traffic simulation is analyzed
and the model
which is consists of basic network model
signal control scheme description model and traffic demand model
is constructed.Signal allocates access right of time
and signal groups describe access rules at intersections in signal control scheme description model. Traffic demand model contains traffic zones and OD matrix. Traffic zone delimits the origin node and destination node of OD matrix
while OD matrix delimits volumes on the network. The corresponding relationship between elements of this model and that of microscopic traffic simulation model is studied with VISSIM as an example. Data is extracted to generalize VISSIM simulation model which proofs the models feasibility for data extraction and exchange.
