Transportation Impact Study Standards

Help shape Aurora's new Transportation Impact Study Standards

The city of Aurora is updating the rules that guide how development projects study and address their impact on our transportation network. The current 2025 Traffic Impact Study Guidelines are being replaced with a more comprehensive document: the Draft 2026 Transportation Impact Study (TIS) Standards.

This update reflects the city's move toward a more multimodal approach to transportation planning. It is one that considers not just vehicle traffic but also pedestrians, bicyclists and transit users. It also introduces a more structured submittal and review process, clearer requirements for when a study is needed, and a stronger emphasis on data-driven safety analysis.

Why we're asking for your input

These standards affect how developers, engineers and consultants prepare studies for projects in Aurora, and in turn, how the city plans for growth in our neighborhoods. Before these standards are finalized, we want to hear from the people who will use them and the community members who will experience their results: traffic engineers, developers and planners.

What you're reviewing

The full Draft 2026 Transportation Impact Study Standards document is available for review and comment from July 20 to Aug. 7, 2026. The document replaces the 2025 Traffic Impact Study Guidelines entirely. All comments are appreciated, from big-picture policy questions to specific technical details.

What happens next

The Development Review Division's Traffic Engineering team will review all comments. Where feasible, the team will revise the draft based on the feedback received before the standards are adopted. A summary of comments received and how they were addressed will be posted.
