Technology and Data South Carolina 3 Minutes Read · published February 21, 2026 Flag of South Carolina

In Columbia, South Carolina, traffic sensor records held by the city or state are public records that can often be requested for planning, research, or legal use. This guide explains how to identify custody of sensor data, where to submit a formal records request, common procedural steps, and what to expect from Columbia departments and South Carolina public records law.

Penalties & Enforcement

The primary enforcement framework for access to public records in South Carolina is the state Freedom of Information Act; municipal compliance is handled by the City of Columbia records and the relevant operating department. Fine amounts and specific monetary penalties for wrongful withholding of traffic sensor data are not specified on the cited pages. Remedies and enforcement are governed by state law and city procedures, as described below.

  • Fines: not specified on the cited pages; statutory remedies exist under the South Carolina code for enforcement of public records obligations.[2]
  • Escalation: administrative request, formal appeal, and judicial enforcement in circuit court (procedural details not specified on the cited pages).
  • Non-monetary sanctions: court orders to produce records, injunctive relief, and official directives; specific orders or suspensions for departments are not specified on the cited pages.
  • Enforcer and complaint pathway: initial contact is the City of Columbia public records office or the operating department (Public Works/Transportation); see the city records request page for submission steps.[1]
  • Appeals and review: parties may seek judicial review under state FOIA provisions; exact time limits and procedures are set by state law and are not itemized on the cited municipal pages.[2]
If a sensor is maintained by SCDOT rather than the city, requests should go to the state traffic data office.

Applications & Forms

The City of Columbia publishes a public records request procedure and an online request form on its official website; required fields, submission method, and any copy fees are described on that page. If data are controlled by the South Carolina Department of Transportation, SCDOT traffic data request procedures apply.[1][3]

How to determine who holds the sensor data

Traffic sensors can be owned or operated by the City of Columbia (local traffic signals and detectors), by SCDOT (state highways and arterial sensors), or by third-party vendors under city or state contract. Confirm custody before you file a request to avoid delays.

  • City-owned sensors: contact City of Columbia Public Works or the records office.
  • State-owned sensors: contact SCDOT Traffic Data and Counts.[3]
  • Contracted vendors: ask the city for procurement or contract references; some vendor data may be subject to contractual confidentiality if properly claimed.
A formal written request that identifies the dataset, date range, and preferred format speeds retrieval.
