Full title and description
Transport information and control systems — Traffic Impediment Warning Systems (TIWS) — System requirements (ISO/TS 15624:2001). This technical specification defines system-level requirements for detecting traffic impediments (using CCTV and image processing) and for communicating warnings to drivers and traffic operators (for example via variable message signs) to reduce secondary accidents and speed incident management.
Abstract
This Technical Specification specifies system requirements for Traffic Impediment Warning Systems (TIWS). It focuses on use of infrastructure sensors (notably closed‑circuit television cameras) with image processing for detection of traffic impediments and on provision of information to vehicles and traffic system operators (for example via variable message signs) to help avoid secondary accidents and accelerate rescue and clearance operations.

- ICS / categories: 03.220.20 (Road transport); 35.240.60 (IT applications in transport).
- Edition / version: Edition 1 (ISO/TS 15624:2001).
- Number of pages: 27 pages.
Scope
This Technical Specification sets out system requirements for Traffic Impediment Warning Systems (TIWS). It addresses detection objectives and coverage, classification of traffic impediments, types of sensors (with emphasis on CCTV and image‑based detection), interfaces to traffic information and control infrastructure and to variable message signs, reporting to traffic operators, and objectives for reducing secondary accidents and improving incident clearance. It is intended to guide procurement, design and integration of TIWS components rather than specify detailed sensor algorithms or hardware form‑factors.
Key topics and requirements
- Definitions and classification of traffic impediments and detection coverage requirements.
- Recommended sensor types and placement (focus on CCTV with image processing).
- System‑level performance requirements for timely detection and notification to drivers and operators.
- Communication and user‑facing interfaces (e.g., variable message signs) and reporting to traffic management centers.
- Operational objectives: avoid secondary accidents, accelerate rescue and clearance, and reduce congestion.
Typical use and users
Intended users include road authorities and traffic management agencies, ITS integrators and equipment vendors, system designers and procurers responsible for incident detection and driver information, and research organizations working on traffic safety systems. The specification is used for high‑level system requirements during planning, procurement and integration of TIWS deployments.
Related standards
ISO/TS 15624:2001 is part of the broader ISO 156xx family of intelligent transport systems standards. Related standards in the ITS domain include various ISO 1562x/1563x/1562x publications addressing ITS functions (for example other ISO 1562x-series documents on collision warning, DSRC application layers and telematics). Users should consult the ISO 156xx series and national/adopted equivalents for complementary requirements and updates.

FAQ
Q: What is this standard?
A: ISO/TS 15624:2001 is a Technical Specification titled "Transport information and control systems — Traffic Impediment Warning Systems (TIWS) — System requirements" that defines system‑level requirements for detecting traffic impediments and informing drivers and operators.
Q: What does it cover?
A: It covers system objectives and requirements for detection coverage and classification of traffic impediments, recommended sensor approaches (notably CCTV with image processing), communication to drivers (e.g., variable message signs) and reporting to traffic management centers to reduce secondary accidents and improve incident clearance.
Q: Who typically uses it?
A: Road and traffic authorities, ITS system designers and integrators, equipment vendors, procurement teams and researchers involved in planning, deploying and operating traffic incident detection and warning systems.
Q: Is it current or superseded?
A: ISO/TS 15624:2001 has been withdrawn (the record shows withdrawal; national catalogs list withdrawal effective 8 November 2024). Users should check with ISO or their national standards body for any direct replacements or newer standards addressing the same domain.
Q: Is it part of a series?
A: Yes — it sits within the ISO 156xx series of standards related to intelligent transport systems and road/vehicle information functions; other ISO 1562x/1563x publications cover complementary ITS topics such as DSRC application layers and collision/forward‑warning functions.
