WORK SESSION 1 CONTEXT DEFINITION Objective: Define context(s) for the corridor. Maximum time: 30 minutes Assignment Working as a team: 1. Review context category definitions from NCHRP 15-52. 2. Identify key characteristics that can aid the determination of context for different areas on the corridor. 3. Determine context boundaries for corridor areas and justify choices. 4. Identify elements missing from the context definition that could aid in determination of context and boundaries. 5. Prepare for a brief (5 min maximum) presentation to present the context decisions and basis for the corridor. WORK SESSION 2 ROADWAY TYPE/USER IDENTIFICATION Objectives: Determine roadway type(s) for the corridor; Identify users for the corridor and their level of importance. Maximum time: 60 minutes Assignment Working as a team: 1. Review roadway type definitions from NCHRP 15-52. 2. Identify key characteristics that can aid the determination of roadway type for the corridor. 3. Identify elements missing from the roadway type definition that could aid in determination of context and boundaries. 4. Review user accommodation definitions from NCHRP 15-52. 5. Define for each user the appropriate corridor classification based on NCHRP 15-52 categories. 6. Identify key characteristics that require consideration to aid the identification of needs and balancing of users for the corridor. 7. Determine possible user accommodation approaches for the corridor and justify choices. 8. Identify elements missing from the user accommodation concepts that could aid in determination of their accommodation and balancing needs. 9. Determine possible roadway type boundaries for corridor sections and justify choices. 10. Prepare for a brief presentation (max 5 minutes) to present the roadway type and user accommodation decisions for the corridor.

WORK SESSION 3 DESIGN OPTIONS Objective: Develop conceptual design options for the corridor. Maximum time: 30 minutes Assignment Working as a team: 1. Review user accommodation and balancing from Work Session 2. 2. Identify roadway design elements required to accommodate users based on the Expanded Functional Classification matrix cell. 3. Develop potential cross sections for each context/roadway type cell to address user accommodation along the corridor. 4. Discuss potential conflicts between user groups and how those may be resolved. 5. Identify elements missing from the Expanded FCS that could aid in determination of the design options. 6. Prepare for a brief (5 min maximum) presentation to present the design options considered and selected for the corridor.

TRB's National Cooperative Highway Research Program (NCHRP) Web-Only Document 230: Developing an Expanded Functional Classification System for More Flexibility in Geometric Design, which documents the methodology of NCHRP Research Report 855: An Expanded Functional Classification System for Highways and Streets builds upon preliminary engineering of a design project, including developing the purpose and need.

In particular, NCHRP Web-Only Document 230 provides additional contexts beyond urban and rural, facilitates accommodation of modes other than personal vehicles and adds overlays for transit and freight.

Two case studies illustrating an application of the expanded system to actual projects are included.
