How to use Highways England's logging environment (HALOGEN)

Register and use HALOGEN, extract HALOGEN reports and integrate HALOGEN data with other applications.

HALOGEN: an overview

HALOGEN is the central source for Highways England traffic management systems logged data.

The database logs real-time and historic data from roadside equipment across the strategic road network. Data sets include matrix and variable message sign settings, emergency roadside telephone and equipment faults, and equipment locations.

Highways England encourages maintenance contractors such as regional technology maintenance contractors (RTMCs) and technical managing agent contractors (TechMACs) to use HALOGEN. For example, contractors can use the logged data to detect roadside equipment failures within their areas of operation.

HALOGEN data

HALOGEN stores logged traffic management system data for various types of equipment used on England’s motorway network, from variable message signs to emergency roadside telephones.

Typical classes of logged data are:

  • faults - for all types of equipment
  • settings on matrix signs
  • settings on variable message signs
  • emergency telephone call data (historic only)
  • device configuration data
  • operational events
  • status changes
  • operator actions

Highways England technical document MCH 1780 defines which traffic management system equipment is logged with HALOGEN and under what conditions. You must be a registered user of the Traffic Systems and Signing (TSS) Plans Registry website to download this document.

Register as a new user on the TSS Plans Registry website.

You can use this information to:

  • monitor and manage current road conditions
  • identify faults in traffic management system equipment
  • monitor the performance of RCC operators

HALOGEN information services

HALOGEN provides data via a number of information services.

Web reporter

A browser-based reporting tool which allows users to extract historic logging information from HALOGEN as a set of predefined reports.

HALOGEN browser

The HALOGEN browser is a map based software application available to download from the HALOGEN site.

It lets you view graphical representations of traffic management system data, either historically from November 2001 onwards or the current state of equipment on the motorway network.

Highways England Technology Maintenance Contractors (RTMCs and TechMACs) use HALOGEN browser to monitor faults as they occur and to investigate and analyse historic fault patterns.

Highways England’s regional control centre operators use the software to monitor the current state of the motorway network. Traffic operation managers use it to help them gain a better understanding of events leading to traffic incidents.

HALOGEN updates the data continuously to give a real-time view of the roads you are interested in.

You can set the browser to display:

  • the area covered by a regional control centre
  • a section of a motorway
  • a user-defined rectangular area on the map

These data types are available in the HALOGEN browser:

  • signal and message sign settings
  • equipment and telephone fault information
  • status of the logging systems
  • faults - equipment and telephone

You can view data by:

  • range - between a specified start and end date or time
  • snapshot – at a given point in time
  • current values – a single snapshot of the most recent state of a device
  • up-to-date – a current value snapshot refreshed in real time

Motorway Incident Detection and Automatic Signalling (MIDAS)

MIDAS monitors traffic flow and speed from sensors in the road, usually every 500 metres.

These sensors can:

  • detect congestion and the build-up of queues
  • automatically trigger alerts on variable message signs to warn drivers of road conditions ahead, including advised maximum speed

MIDAS is currently used on motorways in England that have the highest traffic levels.

Registered HALOGEN users can download MIDAS traffic counting data and operational log files from the HALOGEN user area . Log on to the HALOGEN site

The MIDAS INFO website gives:

  • details of MIDAS site locations
  • MIDAS site configurations
  • specifications for MIDAS controlling equipment.

Register for access to the MIDAS INFO site

HALOGEN data integration

HALOGEN allows partner organisations to directly access logged data via their own systems.

It provides a suite of real-time services that deliver the latest traffic management system information in formats meeting industry standards for data exchange.

Open Travel data Access Protocol (OTAP)

This service provides the latest information through a simple Hyper Text Transfer Protocol (HTTP) request interface that complies with OTAP specifications. All data is returned in Extensible Markup Language (XML) format.

Types of information currently available through OTAP are:

  • message sign device settings
  • signal device settings
  • device setting request
  • device status entry
  • link monitor
  • logging system status

There are also three ‘active’ information topics. These are specially enhanced data streams that aggregate setting, status and fault information into a single, comprehensive view:

  • active message sign
  • active signal
  • active fault

Notification service

User defined subscriptions let you tailor notifications to deliver data matching your specific requirements.

This information includes:

  • message sign device settings
  • signal device settings
  • device setting requests
  • device status entries
  • equipment faults
  • telephone faults
  • link monitor
  • equipment status
  • build states
  • startups and shutdowns

The Notification Service gives the latest traffic management system information through a ‘push’ interface following Common Object Request Broker Architecture (CORBA) standards.

Datex II Service

HALOGEN detects proximity, reason code and restrictive settings from sequences of matrix signals and uses them to determine if a traffic situation is in progress.

HALOGEN’s DATEX II Low Cost Profile Service gives this information to users as ‘situations from signals’ traffic events.

HALOGEN reports

Historic Data Reports

HALOGEN provides four types of historic data reports

Standard Reports

Standard reports provide four types of logged data:

  • faults - including telephone and equipment fault histories, high volume faults and uncleared faults
  • settings - historical data for motorway signs and signals
  • start ups and versions - a summary of software versions for traffic management system equipment
  • toolbox - includes log edits, current system status and log validation

You can download standard reports from the HALOGEN website.

Customised reports

You can request customised reports of historic data from the HALOGEN information services helpdesk helpdesk.tts@mottmac.com tel 0141 222 4666.

You can either discuss your requirements directly with the helpdesk, or provide them with information on one of 3 checklists:

  • simple report checklist - for data needing little manipulation or analysis, eg faults, signal and sign settings and telephone call records - we can usually supply these reports within three days

Download the simple report checklist from the HALOGEN website

  • complex report checklist - covers more in-depth analysis of HALOGEN data. This could include automated, regular reports. We can usually supply these reports within a week, but this depends on the complexity of the request. Automated reports will take a few weeks to agree and implement
  • court data report checklist - for data to be used in a court of law. Highways England must approve all requests from organisations other than the police or the Crown Prosecution Service (CPS)

Download the court data report checklist from the HALOGEN website

Management reports

HALOGEN generates a suite of management reports each month which give a summary of logging activity during the month.

Management reports typically cover:

  • monthly usage: a summary of logging activity including:

    • operational information such as start-ups, settings and telephone call activity
    • maintenance information such as equipment faults, telephone faults and subsystem availability
  • monthly faults: A day-by-day breakdown of faults for the main subsystems including:

    • message signs
    • signals
    • telephones
    • responders
    • transponders
    • the MIDAS system
  • implementation reasons: A breakdown of signal and message sign settings by motorway or road

  • system availability: The amount of faulty time shown as a percentage of available time for the six main subsystems
  • fault monitor: The number of uncleared equipment faults lasting two hours hours or more throughout the month, taken at five minute intervals

You can receive management reports:

  • as PDF/Excel downloads
  • by monthly email

Request management reports from the HALOGEN information services helpdesk helpdesk.tts@mottmac.com tel 0141 222 4666.

Scheduled reports

We can provide sched­uled reports on a daily, weekly or monthly basis. These are mainly used by organ­i­sa­tions interested in tele­phone call log data and fault log analy­sis data.

Types of scheduled reports

HALOGEN development and test environment

If you develop logging systems for use on the English motorway network you can use the HALOGEN development and test environment for systems integration and acceptance test purposes.

The test environment allows software maintenance contractors (SMCs) and Highways England’s HALOGEN manager, Mott MacDonald, to:

  • identify potential logging issues
  • analyse the performance of new data logging interfaces
  • evaluate the received logs

You can access the test environment online via a secure virtual private network (VPN). Highways England usually grants access for a limited period only.
