Research Report 600 Safety and efficiency at intersections

Published: | Category: Integrated land use and transport systems , Research & reports

This report considers evidence on safety and efficiency at intersections, using New Zealand data and international research, and outlines a systematic approach for evaluating the safety and efficiency benefits at intersections, as part of the project development process.

A review of New Zealand and international practices, analysis tools, guides and processes were considered. The authors found very little in the literature to define what is considered to be an acceptable trade-off between safety and efficiency at intersections, largely due to the existing separation of the two fields in all jurisdictions researched. A recommended solution has been presented in the form of a ‘proof of concept’ evaluation framework, which takes into account a range of factors and case studies. It is recommended that the transport sector considers utilising this framework as a decision support tool in ensuring the correct decisions, with respect to delivering against safety and efficiency outcomes, are made at the appropriate stage of the project development.

Keywords: corridor, efficiency, frameworks, intersections, network, objectives, operations, plans, safety, trade-off
