2. Jackson Street corridor
Green bike boxes installed:
Survey of drivers-- indifferent
Survey of cyclists-- spend $ elsewhere

3. Modern Roundabouts

4. Roundabouts:
Reduce speeds and are pedestrian friendly
Reduce severity of accidents and number of injuries (>80%!)
Reduce vehicle delays

6. This works only when police are present
Soft solutions-> Enforcement “If the police would just enforce the speed limit...”
This works only when police are present

7. Speed feedback signs – “I like to see how high I can get the reading.”
200 ft in advance of sign = 2mph drop
At the sign = no change in speeds

8. People quickly burned out--the speeders were often their neighbors!

9. Speed Humps – “I beep my horn every time I go over one.”
The adjacent residents loved them.
The community hated them.

10. East Street
Drivers speed up between bumps to “make up time”
Forces aggressive drivers toward the sidewalk.

11. Just put up a sign! Just post a lower speed limit!
Accident rates increase!

12. Geometric Solutions-- Street Reconfiguration
Use at least two of these three keys:
Lane width
Sight distance
Introduce curves

13. Invites higher speed Invites lower speed  85th % speed = 39mph
Peak speed = 65mph
North Ford Street
85th % speed = 28mph
Peak speed = 40mph
Invites lower speed 

14. Summary THANKS for visiting Golden!
The ‘soft solutions’ don’t work—they are bandaids for bad design.
Alter road geometry—this reduces traffic speeds which greatly enhances liveability.
