Despite the frequency with which people are convicted of multiple DUI offenses, California continues to require that all individuals with a DUI attend a 30- or 60-hour education program. However, these programs aren't that effective.
Natural gas production is growing and many states and communities are reaping the economic benefits. One of the costs, however, will be damage to roads. One hydraulic fracturing operation requires about 600 to 1,100 one-way, heavy truck trips to bring equipment, materials, and sometimes water to and from a well site.
The promise of autonomous vehicles is finally near to being realized and the substantial benefits to society in terms of safety, mobility, and fuel economy cannot be ignored. It is not too early for policy makers to begin to think about the challenges that lie ahead.
This report documents the re-estimation of the mode-destination models in the PRISM model for the West Midlands region of the UK. The models for some purposes represent access mode and station choice, and time of day choice for car drivers.
Self-driving vehicles offer the promise of significant benefits to society, but raise several policy challenges, including the need to update insurance liability regulations and privacy concerns such as who will control the data generated by this technology.
The auto industry has been moving toward more autonomous vehicles for years. Policymakers could benefit from an examination of the technological advances in this area, their benefits and risks, and the potential effects of various regulations — as well as the absence of regulation — on the development of this technology.
Though “microsleep,” commonly referred to as “highway hypnosis,” may enter the public discourse most often when it's cited as the possible cause of a disaster like the Metro-North train wreck, it is responsible for fatal accidents on American highways every day.
In this December 2013 Congressional Briefing, Johanna Zmud and Peter Phleps illustrate two distinct scenarios for the future of mobility 17 years from now and how choices that policymakers make today will affect the future of mobility in America.
To assess congestion charging policies where the charge varies according to the time of day, the Ørestad Transport Model (OTM) for the Greater Copenhagen area has been extended to predict the choice of time of travel for car drivers.
As traditional transportation revenue sources primarily based on gas tax continue to dwindle or stay even at best, the notion of transitioning to a vehicle-miles-traveled fee or mileage-based user fee has come under substantial consideration. Some design strategies can reduce system costs and increase public acceptance of mileage-based fees.
One of the things taken for granted in the United States is the vast network of school buses—about 26 million children ride 480,000 buses every day. But in other parts of the world, getting millions of children to and from the right school, on time, safely, and for a reasonable cost is a significant challenge.
The Sydney Strategic Travel Model (STM) informs long-term transport planning, policy development and infrastructure assessment across the Greater Sydney area. Additional model estimation work has further improved the commute mode-destination model.
If the “user pays” idea is worth saving, the United States needs a different calculation, writes Liisa Ecola. Some states are looking at mileage fees. With mileage fees, you pay based on the number of miles you drive, rather than the number of gallons of gas used.
Mileage-fee rates could be structured to reduce congestion, harmful emissions and excessive road wear, and the enabling technology could support a range of value-added services offering greater convenience and safety for motorists, writes Keith Crane.
