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%

UTC Renewal
Timescales• Contract award September 2010
• System delivered February 2011

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

NotesLast updated 29/4/101. 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.

UTMC CDB – Interdependencies
• Common Database interfaces with all ITS Systems
• Web portal may require links to corporate networks
• Council staff may want access to functions of the CDB

AVL/RTPI - Objectives
• Provide reliable real-time information to passengers through a variety of systems and communications media
• Provide a voice and data communications platform• Enable bus priority at traffic signals• Provide a vehicle location and control system• Be compatible with AVL/RTPI systems operating in other counties
and with other transport providers• Enhance passenger security• Provide information to drivers to aid timekeeping

AVL/RTPI Architecture
www.hertsdirect.org
AVL/RTPI - Benefits• Modal shift
– +1% increase in passengers across London– +5% in Bristol and Liverpool– +8% in East Kent– +28% Leicester
• Benefits– 9 seconds reduction of delay per bus per junction in London at
VA sites with traditional priority– 10 to 20+ seconds reduction of delay per bus per junction in
Leeds at VA sites with intelligent priority– 18% reduction in journey time on a route in Gateshead

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 tosupply
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
