Lesson 18: Shared Roadways.

Objectives:

Upon completion of this lesson, students will be able to:

  1. Describe the different types of shared roadways.
  2. Explain the elements used in designing roadways for the shared use of vehicular and bicycle traffic.

Pre-Instruction:

Components

Activities

Motivation

Have the students describe the problems they encountered when they took their bicycle trip on a shared roadway.

Objectives

Present and explain the two lesson goals listed above (V-18-1).

Information Presentation:

Components

Activities

Information Sequence

Outline the presentation of the lecture (V-18-2).

Information

Discuss where and when to use shared lanes.

Describe the use of wide curb lanes.

Describe the use of shoulder bikeways (V-18-3).

Describe the use of bike routes (V-18-4).

Describe the use of bicycle boulevards (V-18-5).

Review poor practices and other design considerations (V-18-6).

Example(s)

Show examples (e.g., slides, videotape) of the different types of shared roadways cited in the text.

Student Participation:

Activities

Practice

Use the activity provided in the Student's Guide.

Feedback

Provide comment and feedback to the class as appropriate.

Follow-Up:

Components

Activities

Enrichment

Assign reading for Lesson 19.

Have the students take a bicycle ride on a road with bicycle lanes and note what problems they encounter on their trips.

Review

Provide a summary of Lesson 18 (V-18-7).

Exercise

18.9 Exercise

Lesson Objectives:

  • Describe the types of shared roadways
  • Explain the design elements used for shared roadways

Lesson Outline:

  • Wide curb lanes
  • Shoulder bikeways
  • Bike routes
  • Bicycle boulevards
  • Poor practices and other considerations

Shoulder Bikeways:

  • Width
  • Pavement design
  • Transverse joint design

Bike Routes:

  • Continuity
  • Demand
    • Bicycle
    • Vehicular
  • Traffic Control Devices (TCDs)
  • Parking
  • Surface problems

Bicycle Boulevards:

  • Direct, continuous route
  • Have cross-traffic stop
  • Divert vehicular traffic away
  • Use traffic calming
  • Ample signing
  • Protect the bicyclists at crossings

Poor Practices/Other Design Considerations:

  • Sidewalk bikeways
  • Extruded curbs
  • Raised pavement markers (RPMs)
  • Drainage grates
  • Railroad Crossings
  • Sidewalk ramps on bridges
  • Rumble strips

Lesson Summary:

  • There are many ways to allow motor vehicles and bicycles to share the same roadway
  • Use of specific design elements creates a shared roadway that is bicycle-friendly
