Revised process for work zone decision-making based on quantitative performance measures
Abstract
Work zones create one of the most challenging environments for drivers.
Implementing work zones on urban freeways creates many issues, especially with
respect to mobility. Decisions made regarding the work zone should be informed by
quantitative data, collected in work zones, to ensure that the mobility impacts of the
work zone treatments implemented are mitigated. A new decision-making process,
which addresses the shortcomings in the current decision-making processes, was
developed through the course of this research. The new process incorporates a
Performance Measure/Treatment matrix, which recommends multiple performance
measures, each of which is chosen to measure the mobility impacts particular to a
specific work zone implementation. Most importantly, the revised decision-making
process incorporates a feedback loop. Quantitative data collected in work zones is
analyzed after the work zone is complete, to determine the impacts specific decisions
had on mobility in the work zone. The lessons learned in previous work zones are then
incorporated into the decision-making process, lessening the mobility impacts of future
work zones. This thesis develops the new decision-making process, and examines the
issues with the application of the process.
