Characterization of incidents on an urban arterial road

Abstract

The early warning of incidents on urban arterial roads in a congested city can reduce delay, accidents and pollutant emission. Freeway incident detection systems implemented in recent years may not be suitable for arterial incidents. Arterial incident detection is more difficult. The traffic flow on an arterial road is not conserved from the upstream end of a road link to the downstream end because urban traffic does turn in and out of side‐streets, car‐parks and local residences. Roadside friction such as kerbside parking and shopping traffic also tends to create apparent incidents which are in fact frequent and normal events. This paper develops a definition for an arterial incident and describes a case study on an arterial road in Melbourne, Australia. The study shows that detectors upstream of an incident are more useful for incident detection than downstream detectors. It also identifies occupancy and speed as the appropriate parameters to characterise and detect arterial incidents.

Developments and Applications of Simulation-Based Online Travel Time Prediction System

“…For incident detection on arterials, the ADVANCE project (1991)(1992)(1993)(1994)(1995)(1996) performed research mainly along the same line as freeway incident detection (16). Luk et al tried to differentiate arterial incidents from freeways incidents and emphasized the importance of upstream detectors in detecting arterial incidents (17).…”

Development and evaluation of arterial incident detection models using fusion of simulated probe vehicle and loop detector data

“…[7,21,19,18,9,11,12,25]). This study extends previous research by developing and testing various neural network data fusion architectures based on simulated loop detector and probe vehicle data for varying penetration rates [22].…”

Motorway crash duration and its determinants: do durations vary across motorways?

“…Traffic congestion has been a growing issue in many metropolitan areas during recent years , leading to a large proportion of travel delays and lost commuter time, excess fuel consumption, emission of pollutants and ultimately monetary losses. Traffic incidents have been acknowledged as the cause of a considerable share of travel delays in urban areas and account for 25% to 60% of traffic congestion on motorways . This necessitates the identification of the key contributors to congestion and development of sustainable strategies to help decrease its adverse impacts on traffic networks.…”
