MPM Program Plan Goals
Develop and improve measures and reporting techniques
Report on mobility measures for MAP 21 and statewide reporting purposes
Provide guidance on mobility performance measures (MPMs) to State and MPO stakeholders
Stakeholders understand the measures and how they can be used in decision making
Monitoring the MPM Program
Stakeholders are asking for the dataReaction
Learning
Multimodal Performance Measures Source Book is widely used and cited AND Modal offices and districts include defined Mobility Performance Measures in their publications
Behavior
Monitoring the MPM Program
Output • Measures are used in evaluating
alternatives, programming/prioritizing projects within Florida
Outcome • The MPM program makes a
difference in improving mobility

There are two general types of travel time reliability performance measures:
Percent of trips that “succeed”

On-Time Reliability
• Percent of trips made in stable flow traveling conditions – at a threshold operating speed
Highly Reliable• 99+% of trips are made in uncongested traveling
conditions
Mostly Reliable• 95%+ of trips are made in stable flow traveling conditions
Unreliable• Trips made in stop and go traveling conditions
19
Travel Time Reliability for freeway facilities
• % trips with a travel time index < 1.33
• ~ trips under stable flow conditions
• ~ trips traveling at least 45 mph

Travel time variability• The variability of travel times that
occur on a facility or a trip over a period of time

Major Task Topics
Support Mobility Performance Measures Program
• Plan for MPM Program, organize resources, and develop tasks
• Brainstorm new ideas and coordinate with modes, districts, and subconsultants
• Assist with MAP-21• Training• Travel time reliability implementation efforts
• SHRP 2 L38 the pilot testing of SHRP 2 Reliability Analytical Products– Including review of 5 products,
testing, and recommendation for implementation
1. Support/Develop Mobility Performance Measures Program
Report and Analyze Measures
• Develop Source Book:– Review existing Source Book– Update calculation routines– Report new measures– Produce new General Interest Source Book– Implementation and Outreach Plan
2. Report and Analyze Measures
Report and Analyze Measures
• Acquire mobility performance measures’ data:– Assist in the coordination of multimodal
databases– Summarize mobility performance measure
data and provide documentation of the MPM Program
– Provide data analysis through converting data into useful information
2. Report and Analyze Measures
Bicycle and Pedestrian Mobility
• HCM bike LOS model– Update methodology to calculate bike LOS in
the 2010 HCM• Bicycle and pedestrian LOS evaluation– Evaluate bike & Ped LOS on the SHS in
urbanized areas• Sidewalk and bike lane inventory– Account for all bike lanes and sidewalks for
the entire SHS
3. Bicycle and Pedestrian Mobility
Research and Reliability
• FDOT Reliability Model testing• Travel time reliability LOS approach
development and testing• SHRP 2 reliability product implementation
scoping• Trip oriented mobility monitoring
framework development
33
4. Research and Reliability
Other/Future Topics
• Asset Management Plan• Bottlenecks• Managed Lanes• Predictive Model versus Real Data• Accessibility Measure• Economic/Benefit Cost of Reliability• Freight Reliability
5. Other/Future
Completed
• Developed 2 tables• Website for sharing material
Underway
• Definition of road network – MPO vs. FDOT reporting
• Repository of data to support PMs• SHRP Implementation in Hillsborough• Definition of district role in MAP 21
Not started
• D5 Case study on commuter assistance
