Over the past week, I have conducted an analysis on contra-flow bicycle lanes as a potential opportunity at Fort Carson for a few of our one-way streets. The following cities were case studies for determining advantages and design considerations: Boulder, Colorado; Eugene, Oregon; Portland, Oregon; Madison, Wisconsin; and Cambridge, Massachusetts.
I have determined the following as advantages for the addition of a contra-flow bicycle lane:
- Increased connectivity for cyclists in the presence of one-way streets
- Decrease in illegal bicycle travel on one-way streets with a defined legal option
- Sufficient Street Widths capable of addition of a contra-flow bike lane while maintaining existing capacities and posted speeds
- Greater awareness for bicycle traffic results in greater use of the bicycle as a mode of transportation
I have determined the following design considerations for the addition of a contra-flow bicycle lane:
- Pedestrians and motorists do not expect bicyclists traveling in opposite directions of one-way streets, therefore intersecting streets and driveways must have signage indicating contra-flow bicycle traffic
- Contra-flow lane must be well defined and placed on the motorists left side
- Additional pavement markings should be included for contra-flow bike lanes indicating the direction of bicycle traffic
- Traffic signals must have push button mechanism for contra-flow bicycle traffic
Any additional feedback will be more than welcome regarding contra-flow bike lanes. Please either comment at the bottom of this blog post, or email me at firstname.lastname@example.org.
