Planning Time Index

The two dashboards above are separated by road classes. The first dashboard analyzes planning time index for interstates while the second dashboard view state and US routes. The definition of Planning Time is the total travel time that commuters should plan with enough buffer time to include usual delays plus unexpected.

Planning Time Index is the measured travel time divided by the free flow travel time for a segment of roadway.

Why is Data Important Header

Data is more than just numbers. Through performance measures, data allows us to make decisions that will benefit the public for mobility.


The Connecticut Department of Transportation is committed to full transparency in its business of preserving, managing, and developing the State's transportation system. Our customers have a high expectation of us, and it is our desire to exceed these expectations. The establishment of goals, and the achievement of them, is a fundamental cornerstone of any successful business. Through the use of performance measures, the Department will provide the transparency and accountability that our customers expect.


To ensure transparency, we utilize performance measures for tracking data and project purpose. These performance measures are shown publicly in our Power BI dashboards to help understand our goals and see the progress. These measures and dashboards are updated often.

Performance Management: Measures

The Connecticut Department of Transportation establish and maintain performance measures that are reviewed by the CTDOT's Performance Measures Standing Committee to ensure their usefulness in helping the department make strategic decisions for managing its infrastructure assets. Through the process, measures may be created or deleted in the future. The performance measures focus on results and accountability.

Quarterly Performance Measures

Our annual measures are updated quarterly in our dashboards below. The CTDOT measures compliment the National Performance measures. While select measures are similar between the two, CTDOT has additional metrics to track safety, infrastructure, highway reliability, mobility (bus, rail, bicycle & pedestrian), air quality, and project delivery.
