Since 2001 Mott MacDonald has supplied HALOGEN Services to the
Highways Agency (HA). HALOGEN is the logging environment for the
HA's traffic management systems (HATMS), providing centralised
storage, retrieval and dissemination of both current and historical
log data generated by HATMS equipment.
Seven regional control centres gather HATMS log data and are
responsible for operating the English network of motorways and
trunk roads. There is logged data for each type of HATMS equipment
(such as message signs and emergency telephones) operational
events, status changes, operator actions and equipment faults.
This information is used to monitor and manage the current road
conditions, to help identify faults in the HATMS technology, and,
where required, to provide a court record for the state of matrix
signals and message signs.
The HALOGEN system provides key data for maintenance contractors to
focus their activities, providing real-time information on faulty
equipment. This helps provide safe roads, informs travellers and
HALOGEN services are categorised as:
Core services are responsible for ensuring the receipt and safe
storage of HATMS log data.
This provides for the dissemination of HATMS log data and
related and derived information via a range of intuitive tools and
application interfaces. These tools and interfaces allow authorised
users to access HATMS data in real-time and for historic

This involves collecting MIDAS data from subsystems within the
RCC’s and the analysis of MIDAS traffic counting data.
RCC services provide support for control centre systems
including data transfer, remote maintenance access and an accurate
Mott MacDonald designed and implemented HALOGEN services and is now
responsible for supporting and maintaining HALOGEN, plus
maintaining and developing functionality of provided services. The
architecture of the core HALOGEN system has evolved from a secure
data collector to include data warehousing and delivery of
real-time information. HALOGEN’s data warehouse provides online
accessibility to a growing resource of HATMS data.
