TRIMARC (KYTC)

Status: Existing

Description

TRIMARC is a project of the Kentucky Transportation Cabinet (KYTC). TRIMARC operates a 24/7/365 Traffic Operations Center (TOC) in Louisville Kentucky. TOC Operators and staff use an integrated system of Intelligent Transportaton Systems device hardware and software, to analyze traffic conditions and make timely notifications to motorists, of traffic conditions that may negatively affect interstate travel. Incidents may include crashes, disabled motorists, roadwork and other events that can occur on the interstates. We use dynamic messaging signs, camera snapshot views on the TRIMARC website, Notify Every Truck (NET) program, social media and other means to provide real–time information.

The TRIMARC TOC monitors traffic in the Louisville Metro area and the Northern Kentucky area, south of Cincinnati, Ohio. We also provide Freeway Service Patrols (FSP), during the workweek rush hour periods, to assist motorists during their time of need. FSP services, when available and provided, are always free to the public. FSP unit response is prioritized by TOC staff members to ensure we address the most critical needs first.

TRIMARC works to help travelers avoid delays, plan alternate routes and have a safe travel experience. TRIMARC is helping to realize improved response time by public safety officials, prevent secondary crashes and improve air quality through the reduction of traffic congestion.

Physical Standards

Document NumberTitleDescription
ISO 21217Intelligent transport systems –– Communications access for land mobiles (CALM) –– ArchitectureISO 21217 describes the communications reference architecture of nodes called "ITS station units" designed for deployment in ITS communication networks. While it describes a number of ITS station elements, whether or not a particular element is implemented in an ITS station unit depends on the specific communication requirements of the implementation. It also describes the various communication modes for peer–to–peer communications over various networks between ITS communication nodes. These nodes may be ITS station units as described in the document or any other reachable nodes. ISO 21217 specifies the minimum set of normative requirements for a physical instantiation of the ITS station based on the principles of a bounded secured managed domain.
NEMA TS 8Cyber and Physical Security for Intelligent Transportation SystemsThis specification describes how agencies and other transportation infrastructure owner/operators should implement cyber– and physical–security for ITS.
NIST FIPS PUB 140–2Security Requirements for Cryptographic ModulesThis Federal Information Processing Standard (140–2) specifies the security requirements that will be satisfied by a cryptographic module, providing four increasing, qualitative levels intended to cover a wide range of potential applications and environments. The areas covered, related to the secure design and implementation of a cryptographic module, include specification; ports and interfaces; roles, services, and authentication; finite state model; physical security; operational environment; cryptographic key management; electromagnetic interference/electromagnetic compatibility (EMI/EMC); self–tests; design assurance; and mitigation of other attacks.
