Evaluation of the Transferability of Incident Detection Algorithms Developed for Singapore Expressways

None of the past studies cited in the literature compared the performance of algorithms on sites installed with different traffic detector systems. The authors of the present study developed two new algorithms, DV (dual-variable) and CODE (COmbined Detector Evaluation), which used video-based traffic speed and occupancy to detect lane-blocking incidents along Singapore's Central Expressway (CTE). As a case study, transferability of these CTE-developed algorithms was examined in 100 incidents collected from freeways in Melbourne, Australia. Assessed were the differences in traffic detector systems (loop detectors versus video-based), road geometry, and behavior between Singapore and Australian drivers. The recalibrated applications of these algorithms to freeways in Melbourne yielded good detection performance and satisfied the average expected performances of seven traffic management centers surveyed in the US. Results indicate that the detection logic of the algorithms developed for the CTE has good transferability, with a recalibration process, and can also receive traffic inputs from both video-based and loop detectors.
