Abstract
PL42, Congestion and Travel Time Reliability
Performance Measures for SHIFT 2024
April 15 2022 – June 30, 2023
The objective of the study is to assist KYTC to acquire the 2020-2021 probe vehicle data, update the
association between the third-party network and HIS links, update the congestion measure and
calculate travel time reliability metric for SHIFT 2024. Major study components include:
1. Acquire 2020-2021 HERE speed data set for roadways in Kentucky;
2. Perform quality screening of the data set and produce statistics of temporal and spatial
coverage;
3. Run the conflation process developed previously to link the HERE’s Streets network with
KYTC’s HIS network and perform QA/QC to ensure conflation accuracy;
4. Calculate the congestion measure for
a. Statewide network segmented at around ¼ mile – to assist stakeholders identify
congestion hot spots.
b. SHIFT 2024 sponsored projects.
5. Calculate travel time reliability metric for
a. Statewide network segmented at around ¼ mile – to assist stakeholders identify
unreliability hot spots.
b. SHIFT 2024 sponsored projects.
