NTIS DATEX II Portable Travel Time Variable Message Sign (TTVMS) Solution

Created in partnership with Highways England (HE), the NTIS DATEX II Portable TTVMS Solution (previously known as the Datex Journey Time Solution) generates real-time journey time information for road users using data from the National Traffic Information Service (NTIS). Pioneered by MVIS, the system was the first such solution to enable real-time journey time information from the NTOC to be displayed on portable variable message signs (VMS).

Fully compliant with HE’s Major Project Instruction MPI-54-062016 the NTIS DATEX II Portable TTVMS displays journey time information, which is refreshed every five minutes, on any number of VMS-Cs along major project schemes over four kilometres in length to keep road users informed of the travel time to the end of the road works. Congestion or delays are identified within tens of metres of their vicinity ensuring the messages displayed are relevant to the area affected.

Alternative messages can be displayed if the maximum journey time is exceeded and email alerts may be sent to multiple recipients to keep them fully up-to-date, enabling them to override journey time messages if required using MVIS’ WebStudio™.

Key Features

• Messages can be displayed in amber or white.
• Five minute refresh rate is the default setting compliant with Highways England’s Major Projects Instruction (MPI-54-062016).
• Manually set a threshold for each route for the minimum and maximum journey time of any route
• Display alternative messages if the maximum journey time is exceeded.
• Email alerts to multiple recipients if the maximum journey time is exceeded.
• Override journey time messages at any time to display other messages as required.
