Time-Dependent Transportation Network Design Considering Construction Impact
A traditional discrete network design problem (DNDP) always assumes transportation infrastructure projects to be one-time events and ignores travelers’ delays caused by construction work. In fact, … [Read more...] about Time-Dependent Transportation Network Design Considering Construction Impact
From Road Design to Training, MDOT Focus is on Safety
As part of the effort to promote the "Toward Zero Deaths" (TZD) national highway safety strategy, the Michigan Department of Transportation (MDOT) has implemented a number of projects across the Upper … [Read more...] about From Road Design to Training, MDOT Focus is on Safety
Variable Speed Limit Signs: Control and Setting Locations in Freeway Work Zones
Variable Speed Limit Sign (VSLS) Systems enable speed limits to be changed dynamically in response to traffic conditions so that traffic incidents can be reduced significantly on freeway work zones. … [Read more...] about Variable Speed Limit Signs: Control and Setting Locations in Freeway Work Zones
Maintenance of Traffic for Innovative Geometric Design Work Zones
Currently there are no guidelines within the Manual on Uniform Traffic Control Devices (MUTCD) on construction phasing and maintenance of traffic (MOT) for retrofit construction and maintenance … [Read more...] about Maintenance of Traffic for Innovative Geometric Design Work Zones
Webinar: Improving Large Truck Safety Through the Design and Operation of Work Zones
Work zones can create special challenges for drivers of large vehicles, such as commercial motor vehicles, due to space restrictions. Road work must take place within highway rights-of-way and, … [Read more...] about Webinar: Improving Large Truck Safety Through the Design and Operation of Work Zones
