Washington, Simon (2011) Screening to identify large truck potential blackspots : methodological issues and concerns. In BEE Transport Seminar Series, 20 June 2011, Queensland University of Technology, Brisbane, Qld. (Unpublished)
1. Overview of hotspot identification (HSID)methods
2. Challenges with HSID
3. Bringing crash severity into the ‘mix’
4. Case Study: Truck Involved Crashes in Arizona
• Heavy duty trucks have different performance envelopes than passenger cars and have more difficulty weaving, accelerating, and braking
• Passenger vehicles have extremely limited sight distance around trucks
• Lane and shoulder widths affect truck crash risk more than passenger cars
• Using PDOEs to model truck crashes results in a different set of locations to examine for possible engineering and behavioral problems
• PDOE models point to higher societal cost locations, whereas frequency models point to higher crash frequency locations
• PDOE models are less sensitive to unreported crashes
• PDOE models are a great complement to existing practice
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.
