Indianapolis Roundabout Requests & Traffic Study Process

Indianapolis, Indiana residents and property owners often ask how to request new roundabouts or trigger a formal traffic study. This guide explains who handles requests, what criteria and processes apply, typical timelines, and how appeals or enforcement work under Indianapolis municipal practice. It is targeted at neighborhood advocates, engineers, and municipal contacts preparing petitions, data, or applications to the city.

Overview of the Request & Study Process

Roundabout requests normally start with a petition or service request to the City of Indianapolis Department of Public Works, Traffic Engineering division, which evaluates eligibility and may order a formal traffic study. If the location is on a state road or highway, Indiana Department of Transportation (INDOT) jurisdiction may apply.

• Submit initial request or petition to Public Works Traffic Engineering via the city's traffic request channel and provide collision and volume data.
• City staff screens requests and determines whether a traffic study or field data collection is required.
• If a study is needed, traffic counts and intersection turning-movement data are collected during specified hours and seasons.
• Engineering analysis compares safety and operational criteria and recommends treatments, which may include roundabout design, signals, or other measures.

Penalties & Enforcement

Regulation and enforcement for traffic control devices, roadway modifications, and unauthorized works are handled by the City of Indianapolis and by the Indianapolis Metropolitan Police Department where traffic laws are involved. Specific monetary fines or per-day penalties for unauthorized installation or obstruction of public rights-of-way are not specified on the cited municipal pages; consult the municipal code or Traffic Engineering for exact figures and processes.

Typical Timeline & Action Steps

Timelines vary by data needs, seasonality of traffic, and available city resources. A typical path is screening (weeks), data collection (days to weeks), analysis and recommendation (weeks), design and public engagement (months), and construction (subject to budget and permitting).

• Screening and eligibility review: usually weeks depending on staff workload.
• Field data collection: typically scheduled for representative weekdays and may require peak-hour counts.
• Design, public outreach, permitting, and construction: often months to over a year depending on funding and right-of-way needs.

Common Violations

• Unauthorized construction or obstruction within the public right-of-way.
• Installing signs or devices without approval.
• Failure to comply with removal or stop-work orders.
