Biking Directions Widget
Route types
The Biking Directions Widget provides biking routes for cyclists in the San Diego region. The tool suggests three types of routes (Most Separated, Mixed, and Most Direct) based on roadway and bikeway characteristics.
Most Separated: This route type gives preference to segments that are offer the most separation from traffic.
Mixed: This route type gives somewhat less preference for separation from traffic, allowing for some segments with less separation but a quicker route to destination.
Most Direct: This route type gives the least preference to segments with separation from traffic and prioritizes quickness to the destination.
How routes are calculated
In the Model there are seven costs associated with each routing option. Each of these costs are assigned a relative weight in each routing preference, as the options for each cost are: Prohibited, Avoid (Low/Medium/High) & Prefer (Low/Medium/High). While all seven are used in some routing preferences in others not all seven are used. The following is each cost and a description of what it entails:
Busy Roads (Avoided): This cost identifies all road segments that are identified as being either Functional Class 6 (Prime Aretrials) or Functional Class 4 (Major Roads/4 lanes).
Class 1 Lean (Preferred): This cost identifies all roads segments that have Bike Class 1 (Shared Paths) bike facilities.
Class 4 Lean (Preferred): This cost identifies all road segments that have Bike Class 4 (Protected Bike Lanes) bike facilities.
Highway + On Ramps (Prohibited): This cost identifies all road segments that are identified as being either Functional Class 1 (Freeways and Freeway Ramps) or Functional Class 2 (Rural Freeways and Light 2 lane collector streets).
Low Slope (Preferred): This cost identifies all road segments that have a slope value of 0.2 or less. This is calculated by taking the elevation of a segment’s origin point and comparing that to the elevation of a segment’s endpoint.
No Bike Infrastructure (Avoided): This cost identifies all road segments that are identified as not having a bike facility.
One-Ways (Prohibited): This cost prohibits all road segments identified as one-way.
Route Type calculations
The route types listed above are calculated using the above costs. Here is how these differing routes are calculated using the model:
Most Separated: Busy Roads (High), Class 1 Lean, Class 4 Lean, Highway + On Ramps, Low Slope, No Bike Infrastructure (High), One-Way
Mixed Busy Roads, Highways + On Ramps, Low Slope, No Bike Infrastructure, One-Way
Most Direct: Highways + On Ramps, No Bike Infrastructure, One-Way

Data Layers
Bike Lockers/Parking>
iCommute operates and maintains more than 600 secure bike parking spaces at over 60 locations near transit throughout San Diego County. Most of these locations are now equipped with electronic bike lockers, enabling bike parking program participants to use an electronic key at any of the bike parking spots in the region, instead of being assigned to one specific locker at one specific location. The program is FREE. Participants are required to complete an online application and send in a $25 key deposit. They are also required to renew their application every year at no charge and agree to use the locker at least once per week.
Bikeways Coming Soon
In September 2013, the SANDAG Board of Directors approved $200 million to implement the Regional Bike Plan Early Action Program (EAP). SANDAG project managers have working every day to advance these bikeways through major milestones as Capital Improvement Projects (CIP). The Bikeways Coming Soon layer represents these project’s alignments, proposed facility types, and includes links to concept plans and more detailed information at each project’s Keep San Diego Moving webpage. Before they Open To Public (OTP), these projects are subject to change, but regular updates to this layer will be made in conjunction with the TransNet EAP Dashboard.
Bike Routes 2020
This map displays the five classes of bike facilities present in the San Diego region’s roadways. These classifications are based off of the California Bicycle Transportation Act and are the following: Class 1- Multi-use paths, which provide a completely separated right-of-way designated for the exclusive use of bicycles and pedestrians with crossflows by motorists minimized. Class 2- Bike Lanes, which provide a restricted right-of-way designated for the exclusive or semi-exclusive use of bicycles with through travel by motor vehicles or pedestrians prohibited, but with vehicle parking and crossflows by pedestrians and motorists permitted. Class 3- Bike Route, which provide a right-of-way on-street or off-street, designated by signs or permanent markings and shared with pedestrians and motorists. Class 4-Separated Bikeways/Cycle Tracks, which promote active transportation and provide a right-of-way designated exclusively for bicycle travel adjacent to a roadway and which are separated from vehicular traffic. Types of separation include, but are not limited to, grade separation, flexible posts, inflexible physical barriers, or on-street parking. Class 5- Bicycle Boulevards, which do not provide separation from vehicular traffic but do implement features like traffic calming to lower motorized-traffic volumes, speeds, and give bicycle travel priority.
Freeway Shoulder Bike Access
Some freeway shoulders are open to bike riders in coordination with Caltrans. Specific infrastructure elements for people biking along these freeway shoulders varies and use by inexperienced bike riders is not recommended. Obey all regulatory signs and exit the freeway when required.
Other Suggested Routes
These suggested routes provide additional connections and are not official bikeways as per SHC § 890.4 and people biking should use caution in choosing routes to ensure they are appropriate for their skills and equipment.
GTFS Transit Routes and Stops
Public transit routes and stops in San Diego County are managed by the San Diego County Metropolitan Transit System (MTS) and the North County Transit District (NCTD). Bus, commuter, light rail, and trolley routes managed and developed from the General Transit Feed Specification (GTFS) data. GTFS data is provided to the exchange by the transit agencies and processed by SanGIS to create a consolidated GIS layer containing routes and stops from both systems.
Steep Routes
These segments were initially designated as “steep routes” during the 2015 printed bike map update in coordination with consulting firm KTUA and their outreach to local jurisdictions.
