Non-motorized transportation provides a sustainable alternative to the impacts associated with driving. Switching automobile trips to biking and walking improves mobility and air quality. In the SCAG region, the mode share for non-motorized work trips is 3% while the share of all trips is 12%. Non-motorized transportation in the region is supported by land use decisions that promote bike and pedestrian friendly development and facilities that provide pathways and trails for bicycle and pedestrian users. Cities and county transportation agencies in the SCAG region have planned and built a regional bicycle transportation network. The networks consist of off road (Class I) and on-road (Class II and Class III) facilities that interface with transit routes and pedestrian activity centers. Several counties in the SCAG region maintain a non-motorized transportation plan to designate locations for existing and planned bikeway, bike facility improvements and policies to accommodate the needs of cyclists and pedestrians.
Currently, the National ITS Architecture does not recognize any user service specific to non-motorized transportation and does not address individual technologies. In addition, most pedestrian and bicycle projects are locally deployed and are not generally addressed in a regional architecture. The 2011 update to the Regional ITS Architecture will make recommendations for updates to the sub-regional architectures.
