Congestion pricing is gaining a foothold in the management of highway vehicular travel, and with good reason. Congestion pricing, sometimes called demand-based pricing or dynamic tolling, is in the early stages of adoption by state DOTs as a congestion-management practice. But evidence from Virginia, Washington, and Utah’s dynamically-tolled lanes show that DOTs need to be careful how they set their toll rates to manage traffic flow.
When state Departments of Transportation address safety concerns related to motor-vehicle/wildlife crashes, the agencies save lives and reduce economic costs. Crashes involving larger animals – including deer, elk, moose, and bear – are on the rise, and many states consider addressing this safety concern an integral part of their mission. Some states are using innovative approaches to keep wildlife off the roads.
Accelerated bridge construction (ABC) techniques are transforming the replacement and construction of bridges across the country, and commuters are benefiting from shorter construction schedules. The central component of accelerated bridge construction is the use of prefabrication technologies which allow the production of bridge components off-site.
