Autonomous vehicle technology is already here: Cars park themselves, alert drivers to impending dangers, and even apply the brakes in emergencies. But what will it take to unlock its potential for major societal benefits?
Development of natural gas resources has progressed rapidly in Pennsylvania. These activities require many heavy truck trips for equipment and materials, which can damage state and local roads not designed for high volumes of heavy truck traffic.
In an effort to deter distracted driving and traffic accidents, California enacted a ban on hand-held cell phone use while driving. A study examines the issue, the success of the initiative — and what it means for the future.
Although countries with high levels of economic development generally have more personal automobile travel than less-affluent nations, income is not the only factor that determines a nation's demand for cars.
Automobility -- travel in personal vehicles -- varies between countries. This brief summarizes a study of the factors besides economic development that affect automobility and how automobility might evolve in developing countries.
The level of automobility, or travel in personal vehicles, varies among countries. By determining the factors besides economic development that have affected automobility in developed countries, researchers can predict how automobility might evolve in developing countries.
According to consumer research, the ability to consume media, write an email, or even sleep during transport is a key selling point for self-driving cars, which could be available in the near future. Autonomous vehicle technology could also produce a wide range of public benefits.
Security protections on vehicles have not kept pace with systems that control safety features, navigation capabilities, and wireless communication functions. Onboard computer networks will likely become much more attractive to hackers.
In this June 2014 Congressional Briefing, Liisa Ecola discusses growing shortfalls in federal and state funding for surface transportation programs, and the potential of mileage fees (rather than fuel taxes) to reduce those shortfalls while also reducing traffic congestion, harmful emissions, and excessive road wear.
The first HOT lanes in L.A. have improved traffic flow and travel time reliability, are fair to users of the facilities, have improved transit service and have generated revenue needed to fund those improvements from voluntary toll payments.
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.
