Mobility
Mobility means travel between points A and B. The mobility goal calls for providing a network of multi-modal
roadways and operational systems. Achieving the mobility goal entails the effective and efficient manage-
ment of the existing and future roadways, including the improvement of roadways to urban standards as com-
plete and livable streets.

The four primary objectives of the design, implementation and management for the mobility functions of the
roadway system include:

1. Designation of an appropriate functional classification system and maps
The Transportation System Plan calls for developing an appropriate roadway functional classification system
based on travel characteristics and community aspirations. This functional classification system describes
appropriate operational attributes, as well as roadway design treatments and standards. Roadway functional
classification definitions are described at the end of this section.

Streets where Pedestrian Parkways or Streetscape Overlays are to be considered are shown on the Pedes-
trian System Map. These designations identify Arterial and Collector streets where certain design treatments
may be used to enhance pedestrian, bicycle and transit functions while also seeking to provide adequate
motor vehicle capacity resulting in safer, modally balanced streets. The Pedestrian System Map identifies
Pedestrian/Bicycle Districts, Rural Pedestrian Activity Areas, Pedestrian Parkways and Streetscape Overlays.
Design considerations associated with each designation are discussed in the Pedestrian Element of the Ac- ADOPTED TEXT
tive Transportation section of this plan.

2. Providing systems to manage and operate the roadway system efficiently
The plan also calls for improved systems to manage and operate roadways within a constrained urban con-
text. Access management, traffic calming and facility design are important elements of managing the trans-
portation system. Access management reduces conflicts between through movements and vehicles turning
off and onto the roadway, as well as conflicts between motor vehicles and pedestrians or bicyclists. Facility
design addresses roadway safety and operations with striping, geometry, turn movement channelization and
other minor roadway reconstruction. Traffic calming devices may be applied to Local Streets and Neighbor-
hood Routes to attempt to help protect neighborhoods from the intrusion of through-traffic, and from speed
violations. Traffic calming techniques may include signage, curb extensions, traffic barriers, narrowed travel
lanes, planted medians and other features.

Programs that allow better use of the existing transportation system benefit all users and improve system
capacity and efficiency. Transportation System Management (TSM) is a general term used to describe tech-
niques for increasing the efficiency, safety and capacity of a transportation facility without major new capital
improvements. This may include signal improvements, facility design treatments, access management,
managed lanes, turn restrictions, ramp metering, incident response, targeted traffic enforcement and/or
programs that smooth transit operations, among other treatments.
