Mobility/Congestion/Reliability

The MPO is now monitoring commute times.

The Sarasota Manatee MPO (MPO) must either establish a 4-year target a quantifiable target for Travel Time Reliability and Freight Reliability measures or support the Florida Department of Transportation (FDOT) target. Within 180 days after FDOT establishes a targets (November 14, 2018) the MPO must establish targets.

These MAP -21 measures contribute to assessing the National Highway Performance Program and National Highway Freight Program. The reliability performance measures and metrics for the National Highway System (NHS) are:

Metric
  • Level of Travel Time Reliability (LOTTR) – 80th/50th -for each time period and reporting segment on:
  1. Interstate System
  2. Non-Interstate NHS

Measures

  • Interstate Travel Time Reliability Measure: Percent of person-miles traveled on the Interstate that are reliable
  • Non-Interstate Travel Time Reliability Measure: Percent of person-miles traveled on the non-Interstate NHS that are reliable

Top Ranked Unreliable Segments and Intersections

Level of Travel Time Reliability (LOTTR) is a metric used to measure the variability of travel times throughout the system. Data was gathered during 4 different time periods throughout the day (AM, Midday, PM, Weekend). If during any time period, the LOTTR ratio is greater than 1.50 the segment or intersection is deemed unreliable. What this means for the commuter is that they could experience a delay at least once a week.

The MPO supports Advanced Traffic Management System (ATMS) technology to reduce traffic jams, coordinate traffic signals, keep buses on schedule, improve reliability, and manage parking more efficiently.
