University of VirginiaMultimodal Corridor Maturity Model

• Carnegie Mellon Software Engineering Institute developed the Capability Maturity Model Integration (CMMI)

• A maturity model provides– a place to start– the benefit of a community’s prior experiences– a common language and a shared vision– a framework for prioritizing actions– a way to define improvement

• A maturity model can be used as a benchmark for assessing different organizations for equivalent comparison

Multimodal Corridor Maturity Model

• Instead of software design capability of organizations, we focus on ability of statewide transportation corridors to provide robust and varied service

• The Multimodal Corridor Maturity Model borrows from the CMMI framework, viewing each corridor in terms of its– Potential for multimodal investment– Existing multimodal maturity



• Metrics used to identify levels of multimodal maturity– Density (population, housing, jobs, attractions)– Accessibility to attractions by mode within time radius– Percent/amount of mixed use zoning– Mode split– Presence / Quality of intermodal facilities– Multimodal LOS– Accidents/injuries/fatalities by mode, normalized by person-

mile traveled



• Density example– Census 2000 blockgroup density maps– Transit requires density

Mode Service HU / AcreDial-a-bus

Subscription service 3.5-5Local Bus

Minimum, 1/2 mile route spacing, 20 buses/day 4Intermediate, 1/2 mile route spacing, 40 buses/day 7Frequent, 1/2 mile route spacing, 120 buses/day 15

Express BusReached on foot, 5 buses during 2-hr peak period 15Reached by auto, 5-10 buses during 2-hr peak period 3

Light Rail5 minute or less headways during peak period 9

Rapid Transit5 minute or less headways during peak period 12

Commuter Rail20 trains a day 1-2

• Future steps– Define the maturity levels of the MCMM based on metrics– Integrate further data into our research

• Accessibility• Investigate multimodal “LOS”• Intermodal facilities• Global Insight freight data



• Measuring accessibility– Number of opportunities (jobs, households, etc.) within a

specific amount of time from a given location by automobile, transit, or some other mode of transportation

University of Virginia“Multimodal Transportation Districts: A Creative Planning Tool in Florida”• 1999 Florida Growth Management Act authorizes local

governments to establish multimodal transportation districts– Areas in which priority is placed on safe, comfortable,

attractive pedestrian environments, with convenient interconnection to transit

– Supports walking, bicycling and transit use– Enables advance of transportation concurrency

• Transportation facilities be available concurrent with the impacts of development

Presented by Jared Ulmer, Renaissance Planning Group, 04/07/06



• Multimodal Transportation Districts– Density bonuses– Mixed-use zoning– Maximum block lengths– Access management; entrances to stores on minor, rather than major roads– On-site multimodal transportation infrastructure– Off-site shared parking– On-site parking behind rather than in front of buildings– Maximum front setbacks– Buildings oriented to the sidewalk– Ground floor transparency– Streetscaping and on-site amenities

“Multimodal Transportation Districts: A Creative Planning Tool in Florida”




• Multimodal Level of Service– Bicycle LOS (BLOS), Sprinkle Consulting, Inc.

• Presence of bike lane• Proximity to motorized vehicle• Motorized vehicle volume• Motorized vehicle speed• Percentage large trucks or heavy vehicles• Pavement condition• Percent on-street parking

– Pedestrian LOS (PLOS) , Sprinkle Consulting, Inc.• Presence of a sidewalk• Lateral separation of pedestrian and motorized vehicles• Presence of physical barriers and buffers• Motorized vehicle volume• Motorized vehicle speed





• Multimodal Level of Service– Transit LOS (TLOS)

• Service frequency• Pedestrian LOS• Span of service• Pedestrian crossing difficulty• Obstacle to bus stop

– Highway LOS (LOS)• FDOT’s primary planning software (ARTPLAN) calculates

PLOS, BLOS, TLOS, and LOS simultaneously
