Abstract

Freeway interchanges are the interface between provincial highways and local communities. The operation of the interchanges affects both the adjacent municipal roadway environment and the efficiency of the freeway system as it serves commuting and goods movement needs. Cross-streets of freeway interchanges are evolving to accommodate a wider range of travel modes including walking and cycling. There is a need to have a process for balancing the safety needs of active transportation with the operational objectives of maintaining an efficient highway system.

As part of project for the Ministry of Transportation Ontario (MTO), we have developed process for recommending active transportation design alternatives at interchanges. This process is similar to the process used in Value Engineering, which includes defining the operational issues and needs related to active transportation, an office investigation, a field investigation, and a workshop with a multidisciplinary team to achieve a cost effective design alternatives for infrastructure improvements. This process assesses sites on a site-by-site basis to reflect the unique traffic characteristics, operational concerns and physical constraints of each location. The level of exposure to vehicle-pedestrian and vehicle-cyclist conflicts is assessed relative to the number and complexity of conflict points, the severity of conflicts measured by the speed of vehicles at the conflict points, and the volume-exposure measured by the volume of vehicles, pedestrians and cyclists interacting at the conflict point. Through this systematic process we show how provincial and municipal governments can work together to identify active transportation issues and needs, recognize constraints, identify potential alternatives, evaluate and refine design alternatives. This process for integrating cyclists and pedestrians at interchanges has been piloted at a number of locations in Ontario and has led to consensus among both the provincial and municipal stakeholders.

This paper lists potential alternatives for integrating cyclists and pedestrians at interchanges, uses a combination of variables (number and complexity of conflict points, and volume and speed of vehicles) to classify low, medium, and high exposure levels, and presents a process for working with stakeholders.
