Case Studies

1. RTP with SCS(SB 375 Sustainable Communities Strategy)

2. Context Sensitive Design

3. Corridor System Management Plan

Case #1: RTP + SCS

6

Coordinate transportation (RTP) and land use planning (SCS) to achieve: acceptable levels of travel accessibility regional economic vitalitycost-effective infrastructure investments minimal environmental impacts, induced travelConformity with AB32 and SB375

Case #1 Comparison of Alternatives

Alt A: Trend-Line Land Use and Transportation

Alt B: SCS for Transportation

and Land Use Description Almost all growth

occurs in suburban and rural areas as single uses rather than mixed-use sites Attempts to add highway capacity and systems management to keep pace with development trend

Growth plan takes advantage of existing transportation and opportunity sites for infill, TOD and mixed-use.

Tailors transportation plan with multi-modal services, providing accessibility to planned growth areas

Case #1 Comparison of Alternatives

Alt A: Trend-Line Land Use and Transportation

Alt B: SCS for Transportation

and Land Use Advantages

Follows developer and local government planning practices of recent decades

Invests in highway capacity to reduce congestion to benefit goods movement and essential personal mobility

Reduces VMT/capita and GHG as required under AB32, SB375

Economic investment in central areas sites with potential benefits to environment, socio-economic equity

Responds to demographic shifts

Case #2: Context Sensitive Design

10

Arterial creates barrier and economic disincentive through established community

Goal to improve safety and convenience for travelers and affected community and sustain community value

Comparison of Alternatives

11

Alternative A:Conventional Re-Design

Alternative B:Context Sensitive Design

Description Add lanes at intersections as needed to improve traffic LOS

Time traffic signals to accommodate 45mph speeds with minimal delays

Narrow traffic lanes to allow bike lanes or wider sidewalks and landscaping

Redesign for 30mph through alignment curvatures and traffic signals timing

Advantages Improves travel time mobility

Improves bus on-time performance

Reduces emissions

Traffic speeds compatible with adjoining uses

Improves pedestrian environment, economic vitality

Reduces emissions

Difference in Performance Measures Compared with CSMP, Smart Mobility

measures emphasize safety and service for all modes of travel

Smart Mobility measures consider growth and travel inducement impacts of highway capacity increases, and

Resulting growth in emissions relative to climate law.

Three Questions

1. Are performance measures understandable and relevant to the evaluation?

2. Are the measures effective in determining which project alternative is most consistent with Smart Mobility principles?

3. Are there any biases in the set of measures to be corrected through revision to individual measures or the entire set?
