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

GPS Probe Data Key Features

  • Data is provided by the National Traffic Information Service (NTIS)
  • Low latency – Complete journey time sections can be continually monitored in real time
  • Granularity of traffic data – Congestions or delays can be pinpointed to within tens of metres as opposed to identifying a section which could comprise several junctions
  • Changes in journey time can be monitored – It is possible to reliably identify when journey times are starting to increase or decrease and predict when traffic conditions will return to normal
  • Improved coverage – In-vehicle GPS data provides coverage on remote parts of the network where there is generally less or no fixed monitoring equipment; and ensures data is available at times when fixed sensors maybe disabled (e.g. due to roadworks)
  • Less roadside ‘kit’ required on site with corresponding reduction in maintenance liability
