Bicycle Board Members,
The Federal Highway Administration has a course on Bicycle and
Pedestrian Planning:
http://www.tfhrc.gov/safety/pedbike/pubs/05085/chapt4.htm that suggests
considering the following when classifying bike routes.
- Accessibility: This is measured by the distance a bicycle
facility is from a specified trip origin or destination, the ease by
which this distance can be traveled by bicycle, and the extent to which
all likely origins and destinations are served. Some communities (e.g.,
Arlington, VA) have adopted a criterion of having a bicycle facility
within 1.61 kilometer (km) (1 mile (mi)) of every residence. More
importantly, no residential area or high-priority destination (school,
shopping center, business center, or park) should be denied reasonable
access by bicycle.
- Directness: Studies have shown that most
bicyclists will not use even the best bicycle facility if it greatly
increases the travel distance or trip time over that provided by less
desirable alternatives. Therefore, routes should still be reasonably
direct. The ratio of directness to comfort/perceived safety involved in
this trade-off will vary depending on the characteristics of the
bicycle facility (how desirable is it?), its more direct alternatives
(how unpleasant are they?), and the typical user’s needs (in a hurry?
is it a business or pleasure trip?).
- Continuity: The proposed
network should have as few missing links as possible. If gaps exist,
they should not include traffic environments that are unpleasant or
threatening to group B/C (basic and child) riders, such as high-volume
or high-speed motor vehicle traffic with narrow outside lanes.
- Route
attractiveness: This can encompass such factors as separation from
motor traffic, visual aesthetics, and the real or perceived threat to
personal safety along the facility.
- Low conflict: The route should present few conflicts between
bicyclists and motor vehicle operators.
- Cost: This would include the costs both to establish and to
maintain the system.
- Ease
of implementation: The ease or difficulty in implementing proposed
changes depends on available space and existing traffic operations and
patterns.
In another section of the course, they recommend using a "Level of
Service" (LOS) model similar to LOS models used for decades for motor
transportation. They provide an equation that gives a LOS numerical
score and A thru F rating for each street depending on inputs including
traffic volume, speed, percentage of heavy vehicles, pavement surface
condition and outside lane width.
Those of us who are geeky enough to enjoy such a thing might be able to
get a Transportation Enhancement Program grant for a 3 phase project.
In phase 1, we would use the FHWA method to determine bicycle LOS for
Morgantown streets. In phase 2, we could use LOS and its components to
define a bicycle route improvement plan that would constitute the
proposal for phase 3, implementing the high priority improvements.
Anybody want to work on this? The Intent to Apply forms for the 2010
TEP cycle are due November 15. 2 months away.

vehicles
