Designing for bikes at UC Davis is a campus-planning task, not a matter of drawing a lane beside each road. A workable project must connect destinations through a legible network and then resolve the interfaces that determine whether people can use it safely and intuitively: facility cross-sections, intersections, roadway crossings, bollards, signs, pavement markings, lighting and bicycle parking.
The practical rule is to use the older Bike and Transit Network Study to understand what UC Davis analyzed and the current Physical Design Framework and Campus Design Guide to determine how a project should be planned and documented today.

Why UC Davis bike design is a network problem
A bicycle facility succeeds only when it works as part of a continuous trip. At a university, that trip can cross campus roads, walkways, landscape zones, building frontages and transit stops in a few minutes. A short, well-marked segment that ends at an ambiguous intersection is not a complete design. The first question for a project team is therefore, “What destinations and movements must this facility connect?” The detailed questions about pavement, signs and barriers follow from that answer.
UC Davis’s Draft UC Davis Campus Bicycle and Transit Network Study, Part 1 describes a system with a broad range of facilities, including bicycle-only avenues, on-street bicycle lanes and shared bicycle-pedestrian paths. It says the study examined existing infrastructure and community perceptions before making recommendations for the system. Those descriptions belong to a historical draft, not a current inventory or adopted project standard. Read the document for its planning logic and background at Part 1 of the Bike and Transit Network Study.

The same draft attributes an estimate of 15,000 to 20,000 bicycles in use during spring and fall quarters to the 2007 UC Davis Bicycle Plan. That is a historical figure reported in the draft; it is not a current bicycle count, current mode share or a forecast for a new project.
Part 2 turns the network idea into a physical-design checklist. It covers facility types and cross-sections, intersections, roadway crossings, bollards, signage and markings, lighting, bicycle parking and innovative treatments. The study states that “The design guidelines will assist campus planners and designers in addressing bicycle facilities” and that “These guidelines recognize and seek to protect the unique context of the campus.” Both statements are from the study’s Bicycle Design Guidelines section, not from an individual designer. See Part 2 of the study.

| Draft Network Study, Part 1 | Historical conditions, facility categories, community-perception work and the study’s network recommendations. | Current adopted alignments, counts, dimensions or project requirements. The document is an old draft, generally dated around 2008. |
| Draft Network Study, Part 2 | Historical design topics and the rationale for addressing each physical interface. | A substitute for the current edition of campus construction criteria. |
| Physical Design Framework | How campus projects relate to the 2018 Long Range Development Plan and to supporting plans, including the Bike and Transit Network Study. | A complete, project-specific bicycle layout or a list of funded treatments. |
| Campus Design Guide | Current construction design constraints, preferred or required products and details; the page lists “C-22 Bicycle Ramps at Streets and Walks.” | Permission to copy a detail without checking the current edition, project scope and approval requirements. |
| Moving Forward Together | Current sustainable-transportation context for the Davis campus. | Proof that a particular bikeway, crossing or parking project has been funded or built. |
Before issuing drawings, confirm the applicable edition of the Campus Design Guide, the project’s governing documents and any campus comments. A historical study can explain why a treatment was considered; the current project documents determine what can be built.
Start with the network and facility role
Define the destinations and desire lines
Map the buildings, housing, transit stops, major pedestrian approaches, service access and bicycle-parking demand that the project must connect. Identify where a rider enters and leaves the project, not just the limits shown on the civil plan. A facility that connects two isolated blocks but omits the final approach to a building or transit stop creates a gap at the point where users need guidance most.

Choose a facility family deliberately
UC Davis’s historical study recognizes bicycle-only avenues, on-street bicycle lanes and shared bicycle-pedestrian paths. These are not interchangeable labels. A bicycle-only route gives through riders a distinct operating space; an on-street lane places the bicycle movement in the roadway environment; a shared path requires people on bicycles and on foot to negotiate the same space. Select the family that fits the network role, available width, adjacent uses and expected conflicts, then carry that choice consistently through intersections and crossings.
Check continuity at every project boundary
Draw the route beyond the construction limits. At each boundary, record the existing surface, width, grade, markings, signs, lighting and right-of-way conditions. The new work should tell a rider where to continue and should not force an unplanned merge into a walkway, curb return or vehicle lane. If a connection cannot be completed in this phase, show the interim condition explicitly and identify the future tie-in rather than implying that a missing segment is already solved.
Use existing conditions and perceptions as inputs
The draft study combined infrastructure review with community perceptions. A contemporary project team can apply the same discipline: document observed movements, conflicts, maintenance conditions and user concerns, then test whether the proposed alignment addresses them. Do not convert those historical findings into current counts or performance claims; the available material does not establish a current campus-wide count or a measured outcome for any particular treatment.
Design the interfaces that make or break a route
Facility cross-sections and transitions
Show the full cross-section, not only the bicycle strip. Dimension the bicycle operating space, adjacent pedestrian area, buffer or separation, drainage edge, landscape zone and clearances required by the current project criteria. At transitions, identify who has priority and where the surface, grade or operating space changes. A transition should be visible in plan, profile and the sign-and-marking schedule so that the field crew does not have to infer it.
Intersections
At every intersection, trace each legal movement for a person on a bicycle and for a person walking. Resolve turning paths, sight lines, stop or yield control, corner geometry and the relationship between a bicycle facility and pedestrian crossings. A route that is clear mid-block can become ambiguous at a corner if the through movement, turn pocket and crossing markings are not coordinated. Use the same route identity on approach, through the conflict area and on the exit leg.

Roadway crossings
Roadway crossings deserve a separate design decision because they combine movement across traffic with a change in operating context. Show the crossing location, approach alignment, waiting or refuge space where provided, surface treatment, signs, markings and lighting. Check that the crossing is visible from the approach and that a person leaving the crossing can immediately identify the continuation. The appropriate treatment depends on the road, traffic control and campus standards in force for the project; the historical study is not a current warrant table.

Bollards and other access-control elements
Bollards can prevent unauthorized vehicles from entering a bicycle route, but an incorrectly placed post creates a collision hazard and can block mobility devices or maintenance access. Document the reason for each bollard, its visibility, spacing, approach geometry, breakaway or removable function where required, and the people who need access. Coordinate posts with lighting, snow or debris removal, emergency access and the swept path of service vehicles. If access control is unnecessary, omitting the obstruction is often the safer design.
Signs and pavement markings
Legibility is a system property. Use a consistent route message from the approach to the destination, supplementing regulatory controls with directional information where a rider must choose between paths. Mark conflict areas and crossings so that the intended movement is apparent without relying on a person to know the campus. Place signs where vegetation, parked vehicles, poles or building edges will not hide them, and include a maintenance responsibility for replacing worn markings.
Lighting
Lighting should support recognition of the route, people, signs, markings and potential obstructions. Review lighting at intersections, crossings, bollards, curves, narrow sections and bicycle-parking areas rather than checking only average illumination along a straight segment. Coordinate fixture locations with trees, utilities, building entrances and glare-sensitive neighbors. The final criteria and photometric requirements come from the current project documents; the draft network study identifies lighting as a design topic but does not replace those requirements.
Bicycle parking
End-of-trip facilities are part of the network, not an accessory added after the path is designed. Place parking where it is visible and convenient to the destinations it serves, while addressing security, weather protection, accessible routes, service access and future demand. Show the route from the bikeway to the racks or enclosure, including the point where bicycle traffic becomes pedestrian-oriented circulation. Confirm the rack or enclosure product and installation details against the current Campus Design Guide and project standards.

Innovative treatments
An unusual surface, crossing treatment or access-control concept should solve a documented network problem and remain understandable to first-time users. Explain the operating rule, maintenance requirement, emergency and service implications, and how the treatment connects to ordinary segments. Innovation is not a reason to bypass the current review path or to present a historical proposal as an adopted standard.
A practical UC Davis bicycle-design workflow
- Confirm the governing documents. Start with the project’s relationship to the 2018 Long Range Development Plan through the Physical Design Framework. Open the current Campus Design Guide and record the edition, applicable sections and the C-22 bicycle-ramp detail for streets and walks.
- Map the complete movement. Identify origins, destinations, entries, exits, transit interfaces, pedestrian approaches, service routes and future connections beyond the work limits.
- Inventory the existing condition. Record facility type, surface, width, grades, drainage, signs, markings, lighting, barriers, parking and observed conflicts. Date the inventory and distinguish observation from historical information.
- Select the facility role. Decide whether the segment functions as a bicycle-only avenue, an on-street bicycle lane, a shared bicycle-pedestrian path or another treatment allowed by current campus guidance. Explain how it continues at both ends.
- Resolve every interface. Produce enlarged plans for intersections, roadway crossings, transitions, bollards, signs, markings, lighting and bicycle parking. Include profiles and cross-sections where grade or drainage changes matter.
- Coordinate access and operations. Review emergency, service, delivery, maintenance, mobility-device and pedestrian movements. Remove or redesign elements that create an avoidable obstruction.
- Check visibility and wayfinding. Test the approach from each direction, in daylight and after dark where lighting changes the reading of the route. Verify that signs and markings remain visible after landscaping and construction are complete.
- Document approvals and maintenance. Identify responsible parties for pavement markings, signs, lighting, landscape clearance, bollards and bicycle parking. Keep unresolved items in the project decision log instead of leaving them to field interpretation.
Compare design choices with a consistent set of questions
The historical study lists the components; the following comparison lenses help a project team choose among alternatives without pretending that the study supplies a numerical scorecard.
| Evaluation lens | Questions to ask | Evidence to document |
|---|---|---|
| Network role and continuity | Does the option connect the intended destinations and continue clearly beyond the site? | Network plan, boundary tie-ins, destination map and future connection notes. |
| User conflict and movement | How are bicycle, pedestrian, vehicle, service and mobility-device movements separated or prioritized? | Intersection enlargements, crossing diagrams, swept paths and access-control rationale. |
| Visibility and legibility | Can a first-time user identify the route, control and continuation in daylight and darkness? | Sign and marking plans, sight-line checks, lighting layouts and maintenance assumptions. |
| End-of-trip function | Is parking convenient, secure, weather-appropriate and connected to the route? | Rack or enclosure layout, accessible approach, security and operations notes. |
| Campus context and current requirements | Does the treatment fit the campus setting and comply with the current design and construction documents? | Framework consistency statement, current guide references and review comments. |
Common failure modes and how to correct them
Using the draft network as current code
Symptom: A drawing cites a Part 1 or Part 2 recommendation as a mandatory campus dimension. Fix: Label the study as historical background, then verify the actual requirement in the current Campus Design Guide and project-specific review documents.
Designing a segment without its connections
Symptom: The plan ends at the property line or drops riders into an unmarked crossing. Fix: Extend the movement diagram beyond the limits and show an intentional interim or future connection.

Treating signs, markings and lighting as late-stage items
Symptom: The civil plan is approved before the sign schedule, pavement markings or photometrics are coordinated. Fix: Review these elements with the alignment and intersection geometry and assign their long-term maintenance.
Installing parking where leftover space remains
Symptom: Racks are distant from destinations, obstruct a walkway or lack security and weather protection. Fix: Design the final approach and parking area as part of the bicycle route, then confirm products and details against current campus criteria.

How the sustainable-transportation plan fits
UC Davis’s Moving Forward Together identifies itself as the sustainable transportation plan for the Davis campus. It provides forward-looking policy context for bicycle and transit planning. It does not, by itself, establish that a particular bikeway treatment is funded, adopted or installed. Use it to understand the broader transportation direction, then use the Physical Design Framework and current construction guidance for a project decision.
What a complete bicycle-design package should leave behind
- A network diagram showing destinations, continuity and project boundaries.
- An existing-conditions record that separates current observations from historical study material.
- Facility cross-sections and transitions tied to the selected network role.
- Enlarged intersection and roadway-crossing plans with controls, markings, sight lines and lighting.
- A documented rationale for every bollard, sign, marking, fixture and access point.
- A bicycle-parking plan connected to accessible pedestrian circulation and operations.
- References to the current Campus Design Guide, including applicable ramp and streets-and-walks details.
- Maintenance, emergency-access and future-connection responsibilities assigned before construction.
That package treats bike design as UC Davis describes it: a connected system plus the physical details that make each movement understandable. It also keeps the historical draft study in its proper role—valuable background—while leaving current requirements to the campus’s active planning and construction guidance.
