CANADIAN CAPACITY GUIDE FOR SIGNALIZED INTERSECTIONS - 3rd EDITION
CITE has updated this valuable technical resource, widely regarded as fundamental to the understanding of transportation operations related to signalized intersections. The new Guide has been endorsed by the Transportation Association of Canada (TAC) as a national reference on the topic. The Guide will be supported through a joint committee between CITE and TAC.
The Guide includes a comprehensive methodology for analyzing and designing signal phasing and timing for intersections,saturation flow data from across Canada, discussion on transit priority operations, designing for safety, and other relevant topics. Four worked examples are included.
This project has also involved development of the InterCalc software, which replicates the Guide's methodology.
Training on the Guide and the InterCalc software is available, via a one-day workshop. Contact Jim Gough (goughj@mmm.ca) or Glen Holland (glen.holland@ch2m.com)

PROMOTING SUSTAINABLE TRANSPORTATION THROUGH SITE DESIGN GUIDELINES: AN ITE RECOMMENDED PRACTICE
This report recommends site design practices that can be applied through the land development process to promote the use of more sustainable modes of passenger transportation, such as walking, cycling and transit. Its primary purpose is to assist policy-makers and professionals involved in the preparation, review and approval of non-residential development proposals to identify and incorporate features that make sites more accessible to travel modes other than the single-occupant vehicle (SOV). The report also identifies a range of supporting policies and actions that agencies can implement to create an atmosphere conducive to promoting sustainable transportation through site design.
USING OBSERVATIONAL BEFORE-AFTER STUDIES TO EVALUATE ROAD SAFETY PROJECT
Agencies are required to evaluate the safety effects of a specific improvement to compare its net benefit to other improvement options as well as to justify its implementation at subsequent locations. The typical method of evaluating the safety improvements of a treatment is comparing the crash prevalence associated with the transportation facility before and after the treatment implementation (a before-and-after study). A challenge inherent in these studies is that crashes are random and change from year to year, unlike laboratory experiments in which the analyst can control many extraneous conditions. Other parameters that affect the safety of a facility, such as traffic volume and weather conditions, change over time. Consequently, specific evaluation techniques are required to account for changes in order to estimate the true effects of safety improvements.
The main objective of this technical brief is to provide practitioners with a quick reference on the key considerations and components of a valid before-and-after observational study. This document also serves as a tool to increase the level of understanding of before-and-after study techniques so that they can be more effectively conducted in the future.
CANADIAN TRAFFIC SIGNAL REPORT CARD
This document intends to focus attention on the operation and maintenance of traffic signal systems – an activity that can produce one of the highest benefit-cost ratios for improvement to the highway transportation system. The purpose of the 2008 Canadian National Traffic Signal Report Card is to:
- assess the current state of traffic signal management and operation;
- identify deficiencies in traffic signal systems and highlight ways to improve operation;
- improve awareness of the current state of traffic signal systems in Canada;
- create awareness of the congestion-reducing benefits of good traffic signal management and operation; and
- provide a benchmarking tool for jurisdictions to identify opportunities for improvement in traffic signal management and operation.
