Winter Performance Impact
The data reveals that Route 514 is the worst affected by adverse weather conditions, with a performance drop from 55% in clear weather to just 19.9% in snow. This significant decline of 35.1% indicates that the route is particularly vulnerable to winter weather, which may be due to its specific alignment, elevation changes, or the density of stops that impede travel speed during inclement conditions.
Several factors typically contribute to the performance deterioration in snow. These include reduced traction for vehicles, increased travel times due to road conditions, and potential delays caused by snow removal efforts. Additionally, passenger demand may fluctuate during severe weather, impacting overall service efficiency. Understanding these elements can help inform future planning and responses during winter events.
Temperature Threshold Analysis
Critical Temperature Threshold
The critical temperature threshold identified in the data is -20°C. Transit performance is notably higher on days when temperatures are above this threshold, with a performance rate of 49.3%, compared to 46.5% on colder days. This results in a performance drop of 2.8% when temperatures fall below -20°C, indicating that extreme cold negatively impacts operational efficiency.
Main contributing factors to this temperature sensitivity include the increased likelihood of mechanical failures in vehicles, difficulties with track conditions, and challenges in passenger operations, such as delays and disruptions. These factors are exacerbated by lower temperatures, leading to a reduction in overall transit performance during colder months.

Route Vulnerability Analysis
The heatmap on this dashboard visually represents transit performance under various weather conditions, with red indicating poor performance and green signifying good performance. Users can quickly identify areas of concern, particularly during adverse weather events. This tool allows for easy comparison across different conditions, helping to pinpoint where service may be most affected.
Our analysis shows that snow is the most challenging weather condition for the transit system, with an average performance rating of just 46.3% over 135 days observed. This insight is crucial for identifying vulnerable routes that may require additional resources or contingency plans during winter weather, ensuring that service disruptions are minimized for passengers.
Bunching by Weather Conditions
Weather-Related Bunching
Bunching refers to the phenomenon where multiple transit vehicles arrive at a stop in quick succession, rather than spaced out as intended. Weather conditions, such as snow, can exacerbate this issue due to slower travel times, reduced visibility, and increased operational challenges. In Saskatoon, snow has a significant impact on transit schedules, leading to a higher rate of bunching.
In our analysis, snow conditions showed a bunching rate of 46.5 incidents per hour, which is notably higher than the 252.54 incidents per hour during clear weather. This discrepancy may arise from factors like reduced driver efficiency and increased traffic disruptions. To mitigate these challenges, transit operators should consider implementing real-time communication strategies with drivers during adverse weather conditions to improve coordination and reduce bunching. Additionally, please note that bunching detection systems are currently in development to enhance operational efficiency.
