Aiming at the problem that it is hard to scheduling vehicles in ITS,the characteristic and requirement of the workflow model for real-time vehicles scheduling in Grid environments which cross lots of domains and systems was presented.A meta-model of workflow was proposed for ITS vehicles scheduling.It utilizes Petri Net-based flexible workflow model technique and top down layered decomposition approach to create the workflow model.And then a dynamic modifying strategy was proposed in order to suit the ideas and methods of ITS workflow modeling.At last,an algorithm was given to validate the model.
