An Integrated Lane Change Control Method for Freeway Segments With Lane Drop in a Connected Mixed Traffic Environment

Segment with lane drops are very important in freeway systems since they are major constrains to traffic flow and safety. The frequency of capacity reductions and higher safety risks is proportional … [Read more...] about An Integrated Lane Change Control Method for Freeway Segments With Lane Drop in a Connected Mixed Traffic Environment

A Traffic Conflict Risk Assessment Model for Highway Construction Zones Based on Trajectory Data

Highway construction zones present substantial safety challenges due to their dynamic and unpredictable traffic conditions. With the rising number of highway projects, limited accident data during … [Read more...] about A Traffic Conflict Risk Assessment Model for Highway Construction Zones Based on Trajectory Data

Modelling and Evaluation of Work Zone Queues: Istanbul Case Study

Road/lane closures due to maintenance works adversely affect the traffic conditions, causing delays in the various locations of the whole network. In Istanbul, Metropolitan Municipality charge the … [Read more...] about Modelling and Evaluation of Work Zone Queues: Istanbul Case Study
