Optimal Trade-Offs between Construction Cost and Traffic Delay for Highway Work Zones
Highway work zones often cause traffic congestion, resulting in increased road-user delays and vehicle emissions. These negative impacts of highway work zones can be minimized by a number of … [Read more...] about Optimal Trade-Offs between Construction Cost and Traffic Delay for Highway Work Zones
Improving Traffic Flow at Long-term Roadworks
Long-term roadworks on highways are vital as part of roadway and bridge renovations. They generate bottlenecks and can consequently cause congestion and accidents. If the number of lanes is reduced, … [Read more...] about Improving Traffic Flow at Long-term Roadworks
Work Zone User Impact Reference Charts for Bridge Lane Closures
Accelerated bridge construction (ABC) techniques are increasingly deployed in bridge rehabilitation or replacement projects to reduce the onsite construction time. Higher costs of using ABC techniques … [Read more...] about Work Zone User Impact Reference Charts for Bridge Lane Closures
