1 Inter-Urban ITS John Paddington, Consultant, Faber Maunsell Nottingham University, 24 th November 2005

2 Inter-Urban ITS, Nottingham University, 24th November 2005 Lecture Content Why use ITS? M25 Controlled Motorway Active Traffic Management (ATM) on the M42 NASS Decision making tool for ATM

3 Inter-Urban ITS, Nottingham University, 24th November 2005 Inter Urban Network: Context Focus on the road network Already near capacity Building more roads is not the answer Environmentally damaging Politically sensitive issue

4 Inter-Urban ITS, Nottingham University, 24th November 2005 What is ITS? ITS stands for Intelligent Transport Systems Essentially modern technology used in conjunction with transport schemes. Using existing infrastructure better A recap Image

5 M25 Controlled Motorway Variable Speed Limits

6 Inter-Urban ITS, Nottingham University, 24th November 2005 MIDAS Fore-runner of Controlled Motorway Image

7 Inter-Urban ITS, Nottingham University, 24th November 2005 Why Variable Speed Limits? Lower traffic speeds when the road is busy to reduce congestion Aim to improve efficiency of the road Reduce stop / start traffic More consistent journey times Reduce variability Some theory…

8 Inter-Urban ITS, Nottingham University, 24th November 2005 What is Controlled Motorway? Development of MIDAS Mandatory Variable Speed Limits (60, 50,40 mph limits) Speed Enforcement Initially wet film cameras Now Digital Gatsos The System

9 Inter-Urban ITS, Nottingham University, 24th November 2005 M25 Controlled Motorway: M25 CM Picture

10 Inter-Urban ITS, Nottingham University, 24th November 2005 Controlled Motorway Parties involved: Highways Agency TRL Mouchel Parkman Faber Maunsell have been involved since 1999! Faber Maunsell Involvement in the Project

11 Inter-Urban ITS, Nottingham University, 24th November 2005 Controlled Motorway Business Case Development Assess benefits: Journey Time Accident Savings Fuel Saving Assess costs: Installation, Renewal and Maintenance Scheme Assessment(1)

12 Inter-Urban ITS, Nottingham University, 24th November 2005 Controlled Motorway Government Approach: (WEBTAG) Assess wide range of benefits and disbenefits in the following categories: Environment Safety Economy Accessibility Integration Produce a comparison table called an Appraisal Summary Table (AST) See: for detailswww.webtag.org.uk Scheme Assessment(2): WEBTAG

13 Inter-Urban ITS, Nottingham University, 24th November 2005 Controlled Motorway Scheme Assessment(3): Appraisal Summary Table AST

14 Active Traffic Management (ATM) Controlled Motorway 2?

15 Inter-Urban ITS, Nottingham University, 24th November 2005 Active Traffic Management M42 Junctions 3a- 7: Birmingham Multi-Million pound project Uses the latest technology First phase going live imminently The latest scheme M42 J3a-7

16 Inter-Urban ITS, Nottingham University, 24th November 2005 Active Traffic Management Access Control CCTV Based Incident Detection Emergency Refuge Areas Hard Shoulder Management HADECS Digital Speed Enforcement MS4 Variable Message Signs capable of displaying pictograms Not just Controlled Motorway…

17 Inter-Urban ITS, Nottingham University, 24th November 2005 Active Traffic Management The reality ATM Picture

18 Inter-Urban ITS, Nottingham University, 24th November 2005 Active Traffic Management Installation works now complete Three Lane Variable Speed Limits from Late 2005 Four Lane Hard Shoulder Running from Autumn 2006 Access Control: still to be determined Timetable

19 Inter-Urban ITS, Nottingham University, 24th November 2005 Active Traffic Management Advert in Birmingham METRO: Monday 21 st November 2005 ATM Website: Education

20 Network ATM Supervisory Subsystem (NASS) A traffic management tool for ATM

21 Inter-Urban ITS, Nottingham University, 24th November 2005 What is NASS? Computer modelling tool developed by IPL Will be used by ATM Operators in the Control Room Predicts traffic conditions an hour ahead Match conditions to a library of traffic patterns Decide which one of three associated plans will have the most benefit Summary

22 Inter-Urban ITS, Nottingham University, 24th November 2005 What is NASS? A screenshot… Image

23 Inter-Urban ITS, Nottingham University, 24th November 2005 What is NASS? Working for WSP in Basingstoke Ultimate client is the Highways Agency Testing Phase B of the system Offline testing Phase C will be installed in the Control Room Faber Maunsell involvement

24 Inter-Urban ITS, Nottingham University, 24th November 2005 What is NASS? Used to simulate road conditions Graphical modelling tool Each dot is a car! Colours show speed of each car TRL SISTM Simulator Image

25 Inter-Urban ITS, Nottingham University, 24th November 2005 NASS Testing System run for six hour period From 6 am to 12 am Takes six hours for each run! Assess Flows, Speed and Journey times across the network Only two of thirty runs complete so far Process

26 Inter-Urban ITS, Nottingham University, 24th November 2005 NASS Results An example…

27 Any Questions…

28 And as a reminder… We will be holding an informal session in Room B36 from 13:00 to 14:30 Anyone is welcome to drop in and to talk to any one of us.
