Description
Summary:	algorithm #8 using Fuzzy Logic to evaluate the new algorithm to improve its incident detection time and to allow algorithm with California algorithm #8 and California algorithm, The TXDOT (Texas Department of Transportation) algorithm's effectiveness in detecting incidents on freeways. algorithms were not tested during many congestion periods. applying speed, occupancy, and/or volume loop detector data CCTV (closed circuit television) recordings to determine how did not have the best detection times. However, the falsely declared incidents. The results showed that the incidents and in producing the fewest false alarms, but it incidents. Traffic management centers detect incidents by It is expected that the TXDOT Speed algorithm would produce it to perform well in congested areas. numerous false alarms if it were tested during congestion. often the algorithms detected incidents, how long it takes Recommendations were made to enhance the TXDOT Speed response time to incidents with immediate detection of Speed algorithm. This research compares the TXDOT Speed them to detect incidents, and how frequently the algorithms through the algorithms. Algorithm output were compared with to an incident detection algorithm. San Antonio's new To test these algorithms, real data from TransGuide were run traffic management center, TransGuide, uses a new speed based Traffic management centers can reduce emergency vehicle TXDOT algorithm performed best in detecting the most
