11 © PTV AG 2008 11 System Architecture for Traffic Control Planning of the main elements > data acquisition facilities to acquire current traffic and environmental data on site > data preprocessing and processing incl. the elaboration of a suggested control measure in a traffic control centre or sub-centre > data transmission between traffic data acquisition facilities and central facilities > information transmission to the road users, for example by means of variable message signs. Vast experience in Germany and Austria > Many projects since the eighties > Major contractor for Austrian Motorway company (ASFINAG)

12 © PTV AG 2008 12 Operating Principle of all ATM Systems Action display Units Analysis and procession of traffic data Decision generation of display data Aggregation of traffic data Detection collection of traffic data traffic flow

13 © PTV AG 2008 13 System Architecture for Active Traffic Control

14 © PTV AG 2008 14 System Architecture for Traffic Control - Special Subsystems: ASFINAG Video-Monitoring System

15 © PTV AG 2008 15 Germany‘s ITS Policy framework Background > Massive growth of traffic volumes > Especially on motorways > Especially of heavy goods vehicle traffic > Lack of opportunity and funds (!) for extension of physical road infrastructure Philosophy > Active Traffic Management has been seen as “repair” for a long time > Construction, extension and adequate dimensioning of roads was the first choice > ATM is not a standard feature for new motorways > Since 1980’s implementation programs (also driven by industrial support ideas) > In the meantime established based on good experiences > Safety > Capacity and quality of traffic flow > Reduction of incidents and increase of reliability of the major corridors > Implementation plans and programs in all states > Standards, Rules and Guidelines defined for concepts, devices and communication interfaces

16 © PTV AG 2008 16 Framework Program Federal Ministry’s of Transport, Building and Construction and Housing framework programs for traffic control on federal motorways: > 1981 to 1990:budget approx. 140 mill. € > 1991 to 1995:budget approx. 220 mill. € > 1993 to 1997:budget approx. 325 mill. € > 1996 to 2001:budget approx. 300 mill. € > 2001 to 2007:budget approx. 200 mill. € > But Compare: Annual budget for road construction approx. 10 Billion €

17 © PTV AG 2008 17 Costs of Traffic Control Systems Investment costs [per km road length]: > 0.1 to 0.5 mill. € Operation and maintenance costs [Percentage of investment costs]: > operating costs:0.3 to 0.8 % per year > staff costs:0.2 to 1.5 % per year > maintenance 1.5 to 2.5 % per year

18 © PTV AG 2008 18 Assignment of Costs to System Components investment costsoperating costs

19 © PTV AG 2008 19 Systems (Planned/realized) in Germany, Northern Part Green lines: Network control Red lines: Section control

20 © PTV AG 2008 20 Systems in Germany, Southern Part Green lines: Network control Red lines: Section control

21 © PTV AG 2008 21 ATM-measures: Collective Traffic Control Systems Network control/ Route guidance systems > variable direction signs > information panels Section control systems > speed control > hazard warning (weather, congestion, accidents, road works) > tidal flow/dynamic lane assignment Temporary Hard shoulder use Interchange control systems > merging aid > access control (ramp metering)

22 © PTV AG 2008 22 Route Guidance by Variable Direction Signs Influencing the road user‘s route choice. > by substitutive variable direction signs or > by additional variable direction signs It is generally used for the deviation of through-traffic of a network mesh (long-distance traffic) > due to a congestion on normal/alternative route > to harmonize the traffic volumes in network

23 © PTV AG 2008 23 Example of Substitutive Variable Direction Signs Source: Deutsche Aerospace AG

24 © PTV AG 2008 24 Example of an Additive Variable Direction Sign Source: Dambach-Werke GmbH

25 © PTV AG 2008 25 Route Guidance by Information Panels Alternatively use of information panels at important (route choice) decision points of the road network. For the local road user– experienced by daily use > To be warned of incidents or hazards > To change route

26 © PTV AG 2008 26 Example of an Information Panel Source: Dambach-Werke GmbH, Dambach-Vario-System

27 © PTV AG 2008 27 Network Control by dWiSta Panels Additive direction signs are increasingly replaced by dWiSta panels (dWiSta = dynamic direction signs with integrated congestion information). Being freely programmable they provide > a greater variety of display possibilities and > Higher flexibility in use for more possible applications.

28 © PTV AG 2008 28 Recently introduced dWiSta Panel

30 © PTV AG 2008 30... Implementation

31 © PTV AG 2008 31 Section Control Section control includes all systems which at several display points along a road section > indicate a speed limit > warn the road user of traffic-conditioned hazards (congestion, roadwork, accident etc.) > warn the road user of weather-conditioned hazards (fog, wetness, ice etc.) > Subtract/ add lanes (lane signalization). by means of variable message signs.

32 © PTV AG 2008 32 Displays of a Section Control System

33 © PTV AG 2008 33 Example of a Section Control System Source: Dambach-Werke GmbH, Traffic control system A5

34 © PTV AG 2008 34 Effects of Speed Control Reduction of the standard deviation of local speeds due to > smoother traffic flow > greater capacity > harmonisation of traffic flow.

35 © PTV AG 2008 35 Warning of Hazards Warning of traffic-conditioned hazards: > congestion warning > roadworks > accident Warning of weather-conditioned hazards: > fog > wetness > ice In Approach of dangerous spots a speed funnel is used.

36 © PTV AG 2008 36 Example of Congestion Warning Including Speed Funnel Source: Dambach aktuell

37 © PTV AG 2008 37 Tidal Flow Systems Allocation of lanes according to varying traffic loads > Variation in different peak hours > Variation due to special demand situations (events) The information on the current allocation of lanes is given by > overhead arranged lane signals > green arrow for free lane > yellow flashing arrow for lane to be cleared > red cross for blocked lane > lane allocation panels positioned at the roadside.

56 © PTV AG 2008 56 1.Incident detection based on a cooperative report on traffic conditions Workflow 2.Strategy negotiation and implementation by public authorities 3.Strategy transmission to private service provider 4.Strategy compliant replies to routing request Urban Traffic Control Centre (Düsseldorf) Motorway Traffic Control Centre (Leverkusen/RVLZ Köln) Continuous Strategy Negotiation

57 © PTV AG 2008 57 Strategy Compliant Routing The idea behind the cooperation between public and private partners: Strategic Interaction of Services (Routing) In case of an incident, public authorities inform a navigation service provider of an alternative route and ensure an adequate level of service on this route. Navigation (and Web-Based Routing) Considering Strategies  a method, which was for the first time developed within the INVENT research project, is further developed with focus on automatic implementation
