Maps of Calgary show three corridors: Highway 2, Highway 201, and Highway 1, with travel time index (TTI) data color-coded for each corridor.
Description for Maps 2.1, 2.2 and 2.3
The maps of Calgary each contain three corridors:
- Corridor 1 corresponds to highway 2 between highway 201 N in the north and highway 201 S in the south. Its approximate length is 36.5 kilometres.
- Corridor 2 corresponds to highway 201 between highway 2 in the east and Scenic Acres Link in the west. Its approximate length is 19 kilometres.
- Corridor 3 corresponds to highway 1 between highway 1A (Chestermere) in the east and highway 201 E in the west. Its approximate length is 8.5 kilometres.
Each corridor is colour-coded to represent travel time index along its length. The dark purple colour represents a travel time index of 1.00 and the bright yellow colour represents a travel time index of 2.00 or greater. The aggregated corridor-level travel time index is shown in the table below.
Notes: The Travel Time Index (TTI) is the ratio of peak period travel time to free-flow travel time. For example, a TTI of 2.00 means a trip would take twice as long during peak period as the same trip in free-flow conditions. A TTI of 1.00 represents free-flowing traffic.

| Notes: The TTI is the ratio of peak period travel time to free-flow travel time. For example, a TTI of 2.00 means a trip would take twice as long during the peak period as the same trip in free-flow conditions. A TTI of 1.00 represents free-flowing traffic. "N", "S", “E” and “W” refer to the northbound, southbound, eastbound and westbound directions on the corridor (respectively), and "AM" and "PM" refer to the morning and afternoon peak periods (respectively). The morning peak period is defined from 6:00 AM to 9:59 AM, and the afternoon peak period is defined from 3:00 PM to 6:59 PM.
