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 models feasibility for data extraction and exchange.
