Coordinating for priority on urban arterial freight routes
Ramsay, Euan D. & Bunker, Jonathan M. (2005) Coordinating for priority on urban arterial freight routes. In Australian Institute of Traffic Planning and Management National Conference, 28 - 29 July, Brisbane, QLD.
Demands of freight and passenger traffic are often considered to be in competition, particularly on designated urban freight routes that use major arterial signalised traffic corridors. A microsimulation model of an urban traffic corridor in Brisbane was developed in order for corridor performance to be evaluated for alternative priority treatments. The model was calibrated with GPS travel time and trajectory data for a range of vehicle classes typical of those found on Australian urban freight routes. Intersection status was recorded simultaneously by the STREAMS traffic management system, enabling the progression of different vehicle classes to be validated under existing signal timing plans.
The model can be applied to the optimisation of corridor signal timings. Unlike other models, it was possible to define vehicle-specific performance measures, such as delay, number of stops, and a combination of these. The model can be used to find the best combination of signal timings to favour the progression of particular vehicle classes, such as large freight vehicles. The effects on other vehicle classes can be noted; finding that, although being suboptimal for other classes, it may be possible to achieve some overall gains in traffic efficiency.
Citation countsare sourced monthly fromand citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloadsdisplays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
