  6. Traffic management in a DBFM project - CASE E18 Muurla-Lohja Finland Traffic management in a DBFM project- E18 Muurla-Lohja • Typical ITS equipment will be adequate for example 8 - 12 years, whereas the contract for the motorway is for 21 years • the system must be upgraded at least once within the contract period • some of the equipment need some kind of upgrading every 3-5 years (computers, software, ...) to fulfill the functional requirements • Technology developing quite rapidly • demanding to describe adequate requirements • development also a possibility - service provider will have more possible solutions • Operating the traffic management system will be done by road authority

  7. Traffic management in a DBFM project - CASE E18 Muurla-Lohja Finland Existing guidelines and material in the traffic management • Some guidelines are not available, • however various regulation exist: • Variable message traffic sings - Part 1 product standard (EN 12966-1) was available as a draft version • National guidelines for planning of road tunnels was under preparation • defining the national guidelines - starting point for this work was ”EU’s tunnel directive” (2004/54/EY) • Finnra gives out more detailed requirements on variable traffic signs • color, size, pictogram, ... • Some of the requirements for fixed signs is valid to variable traffic signs

  8. Traffic management in a DBFM project - CASE E18 Muurla-Lohja Finland Lack of guidelines • Guidelines for planning the system not available in 2005 • under preparation • The problem of missing planning guidelines was dealt with ”typical solutions” • for example. guidelines for planning of road tunnels • Figure D.1.4.6. Example on location of traffic management equipment near a two-tube tunnel

  9. Traffic management in a DBFM project - CASE E18 Muurla-Lohja Finland E18 traffic management system • Variable speed limits, warning signs and information signs • Incident detection system (Karnainen tunnel 2,2 km) • Monitoring of road weather • Monitoring of traffic • Telecommunication • Electricity • User interface • Technical barriers • between the carriageway • across the carriageway • Continuous surveillance of the state of the system

  10. Traffic management in a DBFM project - CASE E18 Muurla-Lohja Finland Structure of technical requirements • 8.2 Variable traffic management system • 8.2.1 Description • 8.2.2 Guidelines and regulation • 8.2.3 Functional requirements • 8.2.4 Technical requirements • 8.2.5 Method requirements/descriptions

  11. Traffic management in a DBFM project - CASE E18 Muurla-Lohja Finland Description / guidelines • Variable traffic management system: • the contents and overall principles of operation described in a separate document: Highway 1 Turku-Helsinki, Prefeasibility study of traffic telematics - Only in Finnish [Valtatie 1 Turku Helsinki, Liikennetelematiikan esiselvitys, Tiehallinnon selvityksiä 20/2002 ] • Description of the system: • the coverage • objective • Monitoring of road condition and weather: • done accordingly to the Quality system and manual of Finnra’s Road Weather system (ISO 9001:2000 certified).

  12. Traffic management in a DBFM project - CASE E18 Muurla-Lohja Finland Functional requirements • The aim was to use functional requirements as much as possible • sometimes demanding to set clear and precise requirements •  if not possible then technical requirements were set • Distribution of electricity / power supply network • In tunnels, a separate power network is required alongside the normal power network to ensure the operations of traffic management system. • The data communications system , including the client stations for traffic management system shall meet the requirements for uninterrupted power supply (UPS). The UPS equipment in remote use and local control rooms is to be designed so that it can feed the system for 30 minutes. This system includes: ....

  13. Traffic management in a DBFM project - CASE E18 Muurla-Lohja Finland Technical requirements • Monitoring of traffic: • The monitoring equipment must registrate for every vehicle: • time of vehicle passing the cross-section, speed (km/h), length (m), distance to vehicle ahead (s), direction, lane the vehicle was using and the type of vehicle • Quality: • quality requirements (max measurement error allowed) : • speed +/- 1 km/h • amount of traffic +/- 1 % • distance between vehicles +/- 0,01 s • length +/- 0,02 m • passenger cars and vans, trucks, buses, trailer trucks

  14. Traffic management in a DBFM project - CASE E18 Muurla-Lohja Finland Method requirements/descriptions • ”To be used only if not possible to set requirements otherwise” • Cameras: • The quality of the camera picture must be approved by Finnra. The quality must at least the same as the camera pictures for existing Turku – Muurla cameras of traffic management system. Examples were available via internet. • Service provider must show that the requirements are set. • ... this requirements especially important in Finland due to the dark conditions in winter-time

  15. Traffic management in a DBFM project - CASE E18 Muurla-Lohja Finland Quality assurance in the Payment mechanism • Time to repair malfunctions of the system are defined: • if service provider fails to restore the functionality of the system/equipment in the given time, the payment will be lowered (i.e. service provider will be fined) • For example: • Road weather stations are not functioning according to the requirements: 250 € / time, + 10 € every starting hour • 72 hours to fix the equipment • Larger malfunctions might demand for lowering the speed limit, •  the payment mechanism deals with these more severe situations

  16. Traffic management in a DBFM project - CASE E18 Muurla-Lohja Finland ... finally on the requirements • Service provider has got possibility to suggest other solutions of the system • Finnra must approve these solutions • Service provider has got the responsibility of maintenance for more than 20 years • ... •  Possibility to make innovations.
