Importance of Mobility mobility “Providing for people and goods is transportation’s most essential function.” • Mobility performance measures • MAKE SENSE
Dimensions of Mobility To adequately address mobility, all four dimensions should be emphasized and multiple performance measures used. 7
Quantity How much?
Quality How good or bad?
Accessibility How easy?
Capacity / Utilization How much is used?
Mobility Performance Measure A metric composed of a number and a unit of measure (e.g. miles per year) • Those used for goals and objectives • Indicator • (mobility performance measure)
Florida DOT’s Perspective “FDOT is committed to being leaders and innovators in this vitally important area of transportation management” “We track progress toward meeting our own goals” Ananth Prasad FDOT Secretary
How Does FDOT Use Performance Measures? FDOT will establish criteria to evaluate the effectiveness 17
MAP-21 Goal AreasMoving Ahead for Progress in the 21st Century
Performance Evaluation of States and MPOs USDOT will establish criteria to evaluate the effectiveness 20
MAP-21 Requirements The Department’s intent is to supply the MPOs with analyses for all required MAP-21 mobility performance measures
FDOT Recommended System and Freight MAP-21 Performance Measures

Definitions Performance Measure Congestion Delay Travel time reliability
Congestiondefinition • Severity of congestion: • Types of congestion: • 1. Heavy • 1. Non-recurring • 2. Severe • 2. Recurring Congestion (congested conditions) (auto) – a condition in which traffic demand is sufficient to cause the LOS to be at or below FDOT’s LOS standard (note: congestion is not necessarily related to speed or delay)
FDOTs LOS standards • DUrbanized • CEverywhere else • Transitioning • Urban • Communities • Rural
Equivalent Speeds For Urbanized Arterials
Equivalent Speeds For Non-urbanized Arterials
Equivalent Speeds Freeways
Severity of Congestion LOS Heavy Severe Congestion = at our LOS standard HeavyCongestion = below LOS standard SevereCongestion = demand exceeds capacity (LOS F)
Doug McLeod • FDOT
Delay • Any additional time experienced by a traveler • Additional time beyond some norm Delay Delay
Meaning of Delay? Free flow Anything below free flow speed? (HCM) Delay Uncongested Based on uncongested speeds? (TTI) Delay Threshold Based on a reasonable threshold speed (Recommended) Delay Based on LOS Standards Delay LOS
Reasonable Threshold Delay Threshold Threshold Based on a reasonable threshold speed (draft recommendation) Based on a reasonable threshold speed Delay Delay One level better than FDOT’s LOS standards
Travel time reliability definition options Highest 1% TTI50
Travel Time Reliability 80th percentile 95th percentile Free flow time # Trips # Trips Success Measure Travel Time Travel Time There are two general types of travel time reliability performance measures:
Travel time reliability • Arrived on time • On Time Arrival Approach Posted speed limit + 45 mph + # Trips Success Measure Travel Time The percent of trips that succeed … • Didn’t arrive on time
Travel Time Variability • Comparison of variability in travel times # Trips Travel Time There are two general types of travel time reliability performance measures:
Travel time variability Simplified curve The variability of travel times that occur on a facility or a trip over a period of time
