摘要: |
The detection of freeway incidents is an essential element of an area’ s traffic management system. Incidents need
to be detected and bandied as promptly as possible to minimize delay to the public. Various algorithms and
detection technologies are examined to determine combinations offer optimal detection performance.
The objectives of this research are to compile, compare, rank, and recommend incident detection strategies in use
today. Incident management and its components are described in this report to provide background. Extensive
literature reviews, site visits, and interviews have been conducted and continue to be pursued as new incident
detection schemes emerge. The most prevalent and practical incident detection algorithms are coded into software
for testing and performance comparison. Large amounts of traffic data have been acquired for input into detection
algorithms. An integrated incident detection data and algorithm fusion model is proposed as well This model can
be used both as a management tool and as a method to combine data sources and algorithms in ways that take
advantage of their respective strengths in differing circumstances. The status of tasks that are required to complete
this work is also described.
