Road Safety Program and Data Needs Self-Assessment – Informational Report
The purpose of this project was to provide a means for road authorities to better understand the components of a road safety program, and to measure their data collection practices and safety programs against Canadian industry best practice and other similar agencies.
A survey asking about road authorities’ practices relating to in-service road safety reviews and audits; network screening and data acquisition; safety policy documents; before and after studies; safety education and enforcement programs and related activities were conducted. There were 52 individual responses to quality control of the data. The populations of the responding jurisdictions ranged from 1090 to 2.7 million people.
A Review of Canadian Roundabout Experiences
The purpose of this study was to provide some information about roundabouts that is different than the information provided in other existing documents.
The report is intended to be a primer for road authorities in Canada, effectively helping them make informed decisions about roundabout designs.
Pedestrian Crossing Control Guide Update
The Pedestrian Crossing Control Guide provides guidelines on the use of devices for pedestrian crossing control relating to new installations or where existing installations need to be retrofitted. The Guide is primarily intended to augment the information about pedestrian crossing control devices and their applications contained in the Manual of Uniform Traffic Control Devices for Canada (MUTCDC).
The main objective of this Guide is to promote uniformity across Canada with respect to the approach used in the provision of pedestrian crossing control, while improving road safety for these users. This is done through the development of a decision support tool to assist in the decision-making process when:
•establishing the need for controlling the traffic to enable pedestrians to cross the roadway; and
•identifying the type of traffic control device that would be most suitable for the location’s geometry and cross section, vehicular exposure, and pedestrian demand.
This document includes a CD ROM, Pedestrian Crossing Control Guide: Technical Knowledge Base report, which summarizes the literature review and jurisdictional survey results used to prepare the Pedestrian Crossing Control Guide. The Pedestrian Crossing Control Guide (2012) supercedes the Pedestrian Crossing Control Manual, published by the Transportation Association of Canada in 1998.
Completed in 2012, this publication is available online through the TAC bookstore at: http://tac-atc.ca/en
Transit Priority Measures Study
This Guide is a consolidation of Canadian pavement design and management practices. It provides a theoretical understanding of issues, a summary of best practices and is intended to be applicable across Canada for varying conditions and jurisdictions. Tools for the management of transportation infrastructure assets are included.
The Guide emphasizes routine maintenance and preservation as important aspects of pavement management. Key industry issues such as sustainability, climate change and new innovations are highlighted. Low volume road design and management is addressed. The Guide explicitly highlights provincial practices in addition to municipal practices. State-of-the-art is explored and future opportunities are identified throughout the Guide.
The document is a guide rather than a comprehensive design manual and each of its fifteen chapters provides numerous additional resources for further reference.
Completed in 2013, this publication is available online through the TAC bookstore at: http://tac-atc.ca/en
Vehicle Kilometres Travelled (VKT)-Canadian Methodology Information Report
The project objective was to develop a standardized, repeatable method of calculating Vehicle Kilometres Travelled (VKT) that could be used nation-wide. The data on which the method is based should be measurable, easy to understand and simple and cost-effective to collect. The resulting VKT estimates would allow for more meaningful comparison and benchmark among Canadian cities.
The CITE members’ survey was conducted in June 2011. The survey provided valuable information regarding current VKT calculation methodologies in Canadian municipalities. The survey results can be found in Appendix B of the final draft Information Report.
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 the development of the InterCalc software, which replicates the Guide’s methodology.
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 the2008 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.
