The big challenge posed by Secretary Chao is one we have recognized from the outset, and we totally agree with her today. However, this problem can easily be overcome by keeping all of the driver controls intact and installing and testing (by the vehicle purchasers) of a kill-switch that instantaneously turns over control to the driver. This can be phased out over […]
The U. S. Department of Transportation said it is launching an initiative that includes two pilot programs to modernize its own data analysis and integrate traditional datasets with new “big data” sources to gain insights into highway safety. “Advances in data science have the potential to transform the department’s approach to safety research and provide […]
Instead of cars driving as individual units on highways, automated driving systems (ADS) allow cars to connect and exchange information, enabling coordinated movements. That can mean more capacity on roads, and faster, more efficient travel. In one study, a car platooning proof-of-concept with five Cadillacs with automated longitudinal control was tested and evaluated at Aberdeen Proving Ground, a U.S. […]
AASHTO: Motor vehicle travel on all U.S. highways and streets increased 1.2 percent in October from a year earlier – adding 3.3 billion more vehicle miles – and continued a string of record-high volume levels. The Federal Highway Administration in its latest monthly “Traffic Volume Trends” report said motorists racked up an estimated 275 billion […]
Bureau of Transportation Statistics: Transportation plays a vital role in the American economy: it makes economic activity possible and serves as a major economic activity itself. Transportation Economic Trends 2017 highlights important trends in transportation and the economy and explains related economic concepts and data sources for a general audience.
Automated cars and light-duty trucks (from vehicles already on the road equipped with driver assistance technologies to fully driverless cars still in development) pose safety and infrastructure challenges for policymakers. Automated vehicles potentially promise transformative benefits in safety, mobility, and other areas. However, the successful development of these vehicles and technologies may pose a range […]
From the Mountain Plains Consortium Report: Perception-Reaction Time (PRT) and deceleration rate are two key components in geometric design of highways and streets. Combined with a design speed, they determine the minimum required stopping sight distance (SSD). Current American Association of Highway Transportation Officials (AASHTO) SSD guidance related to PRT and deceleration rate are based […]
Office of Highway Policy Information: Traffic Volume Trends is a monthly report based on hourly traffic count data reported by the States. These data are collected at approximately 4,000 continuous traffic counting locations nationwide and are used to estimate the percent change in traffic for the current month compared with the same month in the […]
Transportation.gov: The Federal Highway Administration (FHWA) published new data today showing a record-high 221.7 million licensed drivers in the U.S. in 2016, including 41.7 million – or almost one in five – who are 65 years or older. This age group is growing faster than any other and is far outpacing their teenage counterparts. The […]
