"Caltrans and the UC Davis Advanced Highway Maintenance and Construction Technology (AHMCT) Research Center today released two reports highlighting ways to prevent rare but often deadly collisions involving wrong-way drivers.
One of the prevention measures included in the three-year pilot program — reflectors that alert drivers they are entering the roadway in the wrong direction — proved to be so effective that Caltrans has already installed the reflective markers on hundreds of miles of highways.
'Adding the two-way reflective markers proved to be so effective that Caltrans updated its statewide design standards,' said Caltrans Director Toks Omishakin. 'It’s a low-cost measure we can use throughout the state to deter wrong way drivers and potentially save lives on California’s highway system.'
The program was developed following 10 wrong-way driver related collisions on Sacramento and San Diego area freeways in the first six months of 2015. During the three-year pilot program, Caltrans tested new signage and technology, while UC Davis AHMCT and Caltrans researchers conducted a second study using a vision-based monitoring system, or VBMS, in Sacramento to better understand the causes of wrong-way driving incidents."
