Transportation Design is a division of Calgary’s Transportation Planning business unit and is responsible for identifying traffic bottlenecks in the city transportation network, developing innovative and cost-effective solutions to address the traffic issues and developing detailed designs for the proposed upgrades (projects). The short to medium term upgrades are developed such that they delay the need for major infrastructural investments in the City transportation network.
Typically the bottlenecks are located in constrained and retrofitted environments, meaning there is limited space to make any major changes and that modifications are made at existing and older locations where minor improvements in geometry can significantly improve the traffic operations. The Design division also develops concepts for small and medium transit optimization projects.
The following is a list of some of the projects that the Design division has worked on, organized by quadrant:
Country Hill and Harvest Hill NE intersection improvement
16 Avenue and Home Road NW
Crowchild Tr and 24 Ave NW intersection improvements
Stoney Trail and Sarcee Trail
8 Avenue SE Laneway
Blackfoot Tr and 58 Ave SE intersection improvements
Glenmore and 52 St SE intersection design
Southland Drive and Blackfoot Trail SE intersection improvements
SWCRR - Westhills Way Connection
SWCRR - 90 Avenue SW and Southland Drive connections
SWCRR - Southland Dr and 14 St SW intersection
SWCRR - Anderson Road connection
SWCRR - Glenmore Tr widening and changes to Glenmore/Crowchild interchange
SWCRR - 162 Avenue SW connection interchange
SWCRR - Bow Tr and 85 St SW intersection improvements interchange
The Calgary Transportation Plan and Municipal Development Plan complement each other and underline a long term vision that promotes sustainability, supports the land use and provides more mobility choices to Calgarians by way of walking, cycling, and transit facilities. Throughout the project evaluation and design process, the Design division works closely with Roads, Planning and other business units to ensure all transportation and land-use related aspects have been considered.
The primary focus of the Transportation Design division is to:
- Identify, analyse and evaluate bottlenecks in the transportation network and prepare a prioritized list of optimization projects;
- Develop innovative and cost-effective solutions for high priority optimization projects to;
- Address traffic congestion and safety related issues in the Cit
- Optimize traffic flow for all modes of transportation including walk, bike, transit, trucks and vehicular traffic
- Enhance travel-time reliability in key vehicular and goods movement corridors.
Provide better and safer connectivity to neighbourhoods.
- Enhance transit priority.
- Design the high priority optimization projects in-house for construction by other business units within the Transportation Department;
- Develop design for key ring road connectors
- Undertake Special Projects in response to Council or public inquiries/complaints to address key land-use and access issues.
Road Optimization Engineers:
- Identify traffic bottlenecks, congestion and traffic issues
- Perform traffic analysis
- Brainstorm solutions
- Coordinate with Design engineers and technicians for developing detailed design of the recommended/approved optimization projects
- Coordinate with Road Optimization engineers for developing detailed designs of the recommended/approved optimization projects
- Review models produced by the Design technicians
- Review and provide technical advice and comments on key City transportation infrastructural improvements projects designed by external consultants
- Develop design for several Southwest and West Ring Road connectors.
- Create design models for the design engineers based on scientific and technical knowledge, using industry approved software including AutoCAD Civil3D and Autoturn.
- These models take into consideration active modes of transportation, drainage, safety, and grades required for utilities.
- Calculate material quantities and cost estimates for various projects.
- Review drafters’ work, provide guidance and direct them to complete the design details.
Transit Priority Engineer:
- Explore opportunities for improvements to transit by providing:
- Queue jump lane
- Transit prioritized signal
- Access to existing bus stops/ bus bays
- Optimize traffic signals to reduce transit delays
The team gathers feedback, both internally from City employees and externally from 311 service requests and other methods, to identify locations where improvements could be made. Our engineers then analyze the various locations to determine if these changes are warranted and will benefit the road-users.
Some examples of enhancements include:
- Adjust signal timings to optimize traffic flow
- Reconfigure the lanes to enhance safety and traffic flow
- Extend or dualize left and right-turn bays
- Upgrades to interchange configuration
- Lane Reversal, and
- Access management to enhance performance of traffic corridor
Special projects are generally formed in response to council and/or public inquiries, and can include consultation and delivery of recommendations to the Transportation and Transit committee.
