We had 2 serious wrong-way incidents just last week in a half-million metro, one a double fatal.

Yellow on the left white on the right is in the MUTCD but might be too subtle a cue for some. Perhaps there should be some pavement striping to supplement locations where the red "WRONG WAY" signs are warranted. Maybe double herringbone stripes across the offramp next to the "WRONG WAY" signs with apex pointed in the direction of traffic.

Arrowing every dashed line on a freeway would be a lot more expensive and difficult to implement and would be more difficult to obscure for roadwork.

Special Investigation Report: Wrong-Way Driving

This special investigation report looks at one of the most serious types of accidents that occur on our highways: collisions involving vehicles traveling the wrong way on high-speed divided highways. The goal of the project is to identify relevant safety recommendations to prevent wrong-way collisions on such highways and access ramps. The investigations included in the report take a focused view of the driver and highway issues affecting wrong-way collisions.


Board Meeting: Special Investigation Report

1.2 Severity of Wrong-Way Collisions

The interest of the National Transportation Safety Board (NTSB) in the issue of wrong-way driving stems primarily from the severity of these types of events. Wrong-way collisions occur relatively infrequently, accounting for only about 3 percent of accidents on high-speed divided highways, but they are much more likely to result in fatal and serious injuries than are other types of highway accidents. The severity of an accident is understood in terms of the crash dynamics. The vast majority of wrong-way collisions on controlled-access highways are head-on events.

A substantial body of state research, conducted primarily by state departments of transportation over decades, supports the fact that wrong-way collisions tend to have higher fatality rates than other accidents. A study in Virginia found the fatality rate for wrong-way collisions on controlled-access highways to be 27 times that of other types of accidents. The California Department of Transportation (Caltrans) found a fatality rate 12 times greater compared to all other accidents on controlled-access highways. A study in Michigan found that 22 percent of wrong-way collisions were fatal, compared to 0.3 percent for all highway accidents in the same time frame.

I'm thinking either 1 of 2 things happened, either there weren't any other vehicles traveling in the opposite direction during those 1.7 miles, or they were staying in their right lane which may have caused her to think it was a 2-way road. Can't really say for sure either way, though.

That sounds like a good idea, since it would probably be overkill to have arrows on each stripe. I think signs posted at the side of the road or above are too easily missed, but something on the road to supplement those signs could help ensure people no not to enter that way. If they did paint arrows through the entire stretch of the highway, every tenth or twentieth strip or so with an arrow would be more than sufficient.

Unless you're drinking some serious firewater out in Albuquerque I seriously doubt this is a pressing issue. It's actually really hard to end up the wrong way on a divided freeway - even blotto.

Many years ago, one of my college friends was killed in a head-on collision by a drunk driver who was on the wrong side of the road.

Wrong way drivers are rare but dangerous. Likely most are drunk. It is aggravated by the fact drunk driving is most common at night. While eliminating drunk driving would be ideal it is not practical. Wrong way warnings that catch the attention of the drunks is the next best thing.

In the article nei referenced, the woman drove the wrong way 1.7 miles before crahing into the oncoming vehicle. The wrong way sign was in her range of vision probably 20-30 seconds at most, but after that there probably wasn't much indication of her error. And even though she was drunk and stoned, she had a few of the passengers in the car who either also hadn't noticed or weren't able to warn her in time.
The oldest of these was 9 years old, for Pity's sake! Kids don't know how to drive, and assume the adults will keep them safe.

Drunk. And in the story above, drunk and stoned. That is the problem. Those arrows wouldn't help those drivers a bit.

I agree that they had to be pretty much plastered to end up going the wrong way in the first place, but what prevented them from veering off and crashing into the side rails prior to colliding with the oncoming vehicles?
