This model can automatically provide useful hidden information about the characteristics of the driver population.

ITS technologies such time-dependent as dynamic lane merging (DLM) and variable speed limits (VSL) have been deployed in roadway work zones in an attempt to enhance safety and mobility through vehicular traffic. The merging behavior is con&173;. Dijksterhuis, and K. Efforts to improve safety and traffic flow through merge areas on high volume/high speed roadways have included early merge and late merge concepts and several studies of the effectiveness of these concepts, many using time-dependent drivers merging behavior model in work zone merging areas Intelligent Transportation Systems for implementation. It is found that merging drivers may merge either time-dependent drivers merging behavior model in work zone merging areas early or late, under congestion or uncongested time-dependent traffic condition. time-dependent drivers merging behavior model in work zone merging areas For example, in Michigan approximately 6950 work zone crashes occurred in 1999, of which 47% occurred time-dependent drivers merging behavior model in work zone merging areas at lane closure areas. A majority of traffic crashes in work zones occur at time-dependent drivers merging behavior model in work zone merging areas lane closure areas.
