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

Thoughts on MAP-21 Mobility Performance Measures

There are two general types of travel time reliability performance measures:

Percent of trips that “succeed”

Arrived on timeOn Time Arrival Approach

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

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
