Truck Delay per Mile (key ranking measure) Annual hours of truck delay divided by section length Planning Time Index (reliability) Ratio of 95 th percentile travel time to uncongested travel time Annual Congestion Cost Value of wasted time and fuel

Cornerstone of Texas Freight Mobility Plan Defines an allmode Texas Freight Network Transportation corridors Key freight generators and gateways Source: http://ftp.dot.state.tx.us/pub/txdot-info/freight/meetings/100113-presentation-preliminary-network.pdf, Texas Freight Advisory Committee Slides, Amarillo, Oct 2013
So what do our measurements mean for the TFN? TFN is x% of TxDOT-network.. 60% of VMT 70% of truck VMT 27% of mileage
Top 50 truck bottlenecks 18 roadways (corridors) 14 sections on IH-35 8 sections on IH-10 4 sections each on IH-45 and US-59 Top 5 TFN corridors (in cost) IH-35 (14 sections) 2.6M hours, $195M IH-10 (8 sections) 1.9M hours, $145M IH-635 (3 sections) 0.8M hours, $60M IH-45 (4 sections) 0.7M hours, $54M US-59 (4 sections) 0.6M hours, $45M
Top 50 truck bottlenecks total $671M in lost operating costs and wasted fuel Top 50 truck bottlenecks spread across 18 roadway corridors with IH-35 containing the most at 14 sections.
Time-of-day profile for truck volumes differs from mixed vehicle Data Source: FHWA Office of Policy Information and state DOTs, and TTI analysis
Seeing differences in travel speeds between mixed vehicle and trucks in probe data Urban arterials more-so than rural interstates Weekends (Sat, Sun, late Fri) more-so than weekdays Urbanized areas rather than small urban or large urban Peaks more-so than off-peak periods Truck reference speed Will be incorporated in next TxDOT 100 Most Congested Roadways list
Get as much service as possible from what you have Truck incident management Add capacity in critical corridors Change usage patterns Provide choices Diversify development patterns Realistic expectations

Monitoring performance What if? Project prioritization, decision-making Special events, what is the effect of X? Related policy/funding decisions
Understand time required to traverse network Understand risk by using variability of travel times Travel time by time-of-day to help schedule delivery routes Avoiding particular bottlenecks to improve efficiency Distribution center location
Texas is on the national scene Interest in what Texas is doing per performance measures/freight for decisionmaking Lots of opportunity Improving datasets Expanding/integrating modes
Congestion impacts on trucking measurable and substantial Provides input to decision-making Supports freight planning efforts at TxDOT Data are continuously improving Texas in an enviable position
