The more relevant comparison, he said, is traffic deaths per million miles driven, not per year. Rawson could not provide those statistics for the mph sections of I and I Traffic deaths in Texas fell from 3, in to 3, last year, a 21 percent drop. Nationwide, traffic deaths fell 28 percent in that period, comparable to the decline on the two interstates with the mph limit. Retting, who was with the Insurance Institute for Highway Safety at the time, studied speeds on those roads after TxDOT increased the limit from 75 to 80 mph.
According to his analysis in the Journal of Safety Research, I saw a 9-mph increase in average speed, and I had a 4-mph average increase. The portion of vehicles going over 80 mph increased from 1 percent to 10 percent on I and from 4 percent to 7 percent on I The vehicle safety improvements and the decreasing highway deaths in recent years may have created a false sense of the relationship between safety and speed, he said.
In , Norwegian Rune Elvik, chief research officer for the Institute of Transport Economics at the University of Oslo, did a so-called meta-analysis of 98 studies, conducted over almost 40 years, of the nexus between road speed and traffic fatalities.
When TxDOT opened the northern section of Texas and two connecting toll roads, it paid the Texas Department of Public Safety to dedicate extra troopers to the road. The new stretch of Texas , despite the higher speed limit, will get the same level of enforcement as any other road in the state highway system, officials said.
In an opening promotion meant to allow potential customers to familiarize themselves with the road, it will be free to drive until Nov. The higher limit applies to drivers of cars, light trucks and light trucks pulling trailers during daylight hours. Drivers of trucks, truck tractors, trailers, and semitrailers are limited to 70 mph. The limits drop to 65 mph after dark for all vehicles. Some truckers can't come close to 70 mph. Earl Hawley, a West Virginia trucker, drives a company rig that's got an engine governor that won't allow him to surpass 68 mph.
It'd be more miles per hour I could cover. Please enter email address to continue. Please enter valid email address to continue. It's the legal limit on this mile stretch of a new toll road between Austin and San Antonio.
Texas already has 80 mph limits on some highways, 75 mph on others, yet the speeds are a sedate 55 to 65 mph on through cities and towns. Why 85 mph on this road? It's a toll road, built by a private company Cintra-Zachry, to Texas Department of Transportation specifications. The company didn't set the speed limit--the Texas Legislature did, in its last session.
Eighty-five miles an hour sounds extreme — and company spokesman Chris Lippincott understands the concerns.
