- Increase alertness of drivers
- Reduce Vehicle Speed
- Enhanced signs with
lights significantly
lowers vehicle speed
- Reduced speed does not necessarily mean a decrease in WVC
- GOALS
- PROS
- Does not restrict animal movement
- Decreased speed can lessen severity of collisions
- CONS
- Standard Signs are ineffective
- Distraction to drivers
- Contributes to Roadway clutter
- GOLDEN, COLORADO
