Merging Vehicles and Lane Speed-Flow Relationship in a Work Zone
In addition to closed merge lanes as physical bottlenecks of work zones, traffic oscillations caused by merging vehicles at multiple locations could reduce work zone capacity. This study took a … [Read more...] about Merging Vehicles and Lane Speed-Flow Relationship in a Work Zone
Validating the Performance of the FHWA Work Zone Model Version 1.0: A Case Study Along I-91 in Springfield, Massachusetts
Central to the effective design of work zones is being able to understand how drivers behave as they approach and enter a work zone area. States use simulation tools in modeling freeway work zones to … [Read more...] about Validating the Performance of the FHWA Work Zone Model Version 1.0: A Case Study Along I-91 in Springfield, Massachusetts
Optimization of Work Zone Segments on Urban Roads Using Cellular Automata Model in Mixed Traffic
Increased delays and reduced speeds in work zones leads to congestion. This can be improved by optimizing the work zone length. The focus of this study is to model work zones using cellular automata … [Read more...] about Optimization of Work Zone Segments on Urban Roads Using Cellular Automata Model in Mixed Traffic
Feasibility of Lane Closures Using Probe Data
To develop an adequate traffic operations management and congestion mitigation plan for every roadway maintenance and construction project requiring lane closures, transportation agencies need … [Read more...] about Feasibility of Lane Closures Using Probe Data
