UTC Renewal
Outstations
• Replace existing legacy Outstation Transmission Units (OTU’s)
• Bring compliance with UTMC principles
• Embracing the efficiencies of IP transmission
www.hertsdirect.org
UTC Renewal - Benefits
• The UTC system runs SCOOT (Split Cycle Offset Optimisation
•
•
•
Techniques) software.
SCOOT achieves an average saving in delay of about 12% over
validated Fixed Time Plans.
Additional savings of 3% per year are likely for every year that a
Fixed Time Plan ages.
Communication costs reduced by approx. 60%

UTMC Common Database (CDB)
CDB is the UTMC central hub, enabling
• A coordinated, centralised approach to monitoring and
managing traffic
• A traffic and travel website
• Distribution of transport information via the media
(radio/TV/Smart phones)
• A consolidated, single user interface
• Close co-ordination with adjoining Local Authorities and
the Highways Agency
Contributes to a number of LTP objectives

Notes
Last updated 29/4/10
1. Paxton Access software programs key fobs (used to lower the bollard in Ware) and logs all
activity related to access. MX4 scada software is used for bollard control and monitoring. The
Macs Solutions bollard RMS software will be transferred to the Siemens RMS PC.
2. ADSL connection from Eclipse using D-Link routers. Images from a single camera can be
viewed in Highways House. Watford CCTV control centre (at Charter Place) have to be called
to request camera switching.
3. Routers are provided by Regional Services Ltd (RSL) and are Wetermo model DR-200 or
DR-250.
4. Westermo DR-250 router fitted with Vodafone SIM card supplied by Dambach.
5. Westermo DR-250 router supplied by Dambach.
6. Router with Vodafone SIM card.
7. Car park data transferred via hard-wired link (along side of building).
8. Uses port on D-Link DSL 524T modem that is for ePIPs in Highways House.
9. DSL routers.
10. Church, Gade, Charter/PA, Queens, Kings, Sutton.
11. Maltings – ADSL, London Road – GSM, Bricket Road – ADSL, Multi Storey – ADSL,
Christopher Place – unknown.
12. Watford, Potters Bar, Hertford, Cheshunt.

•
•
•
•
•
•
Provide reliable real-time information to passengers through a

Automatic Number Plate Recognition (ANPR)
Journey Time Monitoring System (JTMS)
• Journey Time Measurement using ANPR
•
provides traffic data by identifying the same
vehicle at two or more points in a road
network from the recognition of the
vehicle's number plate.
ANPR cameras are strategically deployed
to capture number plates along road
networks providing real time monitoring,
which in turn formulates travel times along
the road network.
www.hertsdirect.org
ANPR/JTMS - Benefits
•
•
•
•
•
•
•
•
Live monitoring of the effectiveness of traffic management schemes
Early warning of traffic incidents
Improve journey time reliability
Reduce disruption caused by major incidents
Provide alternative route advice to minimise the effect of congestion
and incidents
Minimise delays due to roadworks
Influence road users' decisions before they set out on a journey
about route, time and means of travel
Reduce the effects of congestion
www.hertsdirect.org
Variable Message Signs (VMS)
•
•
•
•
Provision of information in a timely manner
Local incident management
Reduction in delay
Supporting diversion routes and controlling traffic on these routes
www.hertsdirect.org
Car Park Guidance Signs
• Excess queues at car parks;
• Congestion on the surrounding road network;
• Poor air quality
Provides greatest benefit when demand for
off-street parking is approximately equal to
supply
www.hertsdirect.org
CCTV
• Incident detection and management
• Provide traffic information through various
•
•
media services
Manage traffic in urban areas through the
use of an UTMC system
Monitor weather conditions of highway
