Management of competing demands on urban freight corridors
Ramsay, Euan D. & Bunker, Jonathan M. (2007) Management of competing demands on urban freight corridors. Road and Transport Research: a journal of Australian and New Zealand research and practice, 16(3), pp. 3-15.
This paper compares the performance under various scenarios of an urban traffic corridor section subjected to a range of vehicle types. A micro-simulation-based model of the corridor was developed from first principles to stochastically assign characteristics and headways for each vehicle and then to track each vehicle as it moved along the corridor. Kinematic behaviour of the different vehicle types (ranging from passenger cars through to B-doubles) were obtained from GPS data collected during a series of chase car surveys on an urban arterial freight route in suburban Brisbane. Corridor performance was reported in terms of intersection capacity and delays as well as travel speeds and stop rates for each vehicle type. The performance of the corridor was found to be sensitive to traffic control measures including the speed limit and traffic signal controller settings such as cycle time and progression design speed. A range of freight policy scenarios were examined, including the effects of increasing freight volumes, choice of freight vehicles used, and vehicle type-specific lane restrictions. Some policies having the potential to improve corridor traffic performance and freight efficiency were able to be identified.

Citation counts are sourced monthly from and 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 downloads displays 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.
