What is ISO/TS 16951 about?
ISO/TS 16951 provides formal procedures and two, alternative, methods (users are advised to choose whichever of the two suits their individual requirements) for determining the priority of on-board messages presented to drivers of road vehicles by transport information and control systems (TICS) and other systems.
ISO/TS 16951 is applicable to the whole range of TICS in-vehicle messages, including traveller information, navigation, travel and traffic advisories, “yellow pages” information, warnings, systems status, emergency calling system information, and electronic toll/fee collection, as well as to messages from non-TICS sources such as telephone, warnings and tell-tales.
NOTE-
ISO/TS 16951 is applicable to systems that allow the free generation of messages, it neither provides guidance on how to use the messages deriving from its procedures nor is it applicable to mandatory or legally required messages.
Who is ISO/TS 16951 for?
ISO/TS 16951 on ergonomic aspects of transport information and control systems (TICS) is useful for:
- Vehicle regulator authority
- Transport industry
- Examiner and evaluator of human factors and road safety
- Driver of vehicle
- Road vehicle manufacturers and TICS suppliers
- Designers of message management systems for in-vehicle
Why should you use ISO/TS 16951?
Priority is one of the parameters to consider in determining when, where and how system messages are displayed. As TICS applications are deployed, the number and frequency of TICS messages presented to drivers can be expected to increase.
ISO/TS 16951 establishes two prioritization methods for TICS and other system-initiated messages or driver-requested messages presented to you while driving. Other prioritization methods are possible. ISO/TS 16951 provides a primary method that takes criticality and urgency ratings of such messages into consideration when calculating a priority index. This will help you compare all possible messages to form a priority matrix. It provides road vehicle manufacturers and TICS suppliers with a consistent basis for the management of messages competing for your limited information processing capability. This, in turn, it will reduce your workload and help ensure that the most important messages reach you.
Briefly, ISO/TS 16951 is intended for those involved in the design of message management systems that integrate in-vehicle messages. It describes how to establish message priorities. It also specifies criteria for message prioritization and, therefore, serves as an evaluation tool for TICS installed in vehicles as standard equipment and for after-market TICS devices.
What’s changed since the last update?
