TRAFFIC MANAGEMENT ON MOTORRING 3

• The Danish Road Directorate's largest ITS
  investment in one project so far
• In the summer 2003 a resolution on the
  construction work was adopted by the Danish
  parliament.
• The resolution holds a budget of DKK 1.790 mio.
  kr. (approx. 240 mio. Euro), including about 10
  set aside for traffic management during
  construction

4
HOW TO SUCCEED

• How did we manage to get the stakeholders to
  realize the needs for advanced traffic management
  on such a large scale?
• A combination of logical and structured
  thoroughly analysis, experiences from the use of
  traffic management at previous road constructions
  and documentation of effects

5
STRUCTURE OF PRESENTATION

• Decision process
• Proposal for solutions
• Status for the project

6
VVM

• Investigation of the traffic, environmental and
  economical effects of a road enlargement
• An essential part of the investigation is the
  planning of traffic management during road
  construction

DECISION PROCESSFOR ITS
8
GATHERING OF NECESSARY INFORMATION

• Success criteria
• Existing conditions
• Planned execution of the road construction

9
SUCCESS CRITERIA

• The number of accidents must not increase in the
  construction period
• The road users should be of the opinion that the
  Roads Directorate makes a good effort to maintain
  the traffic flow on an acceptable level
• The road users shall receive a good and effective
  traffic information regarding alternative routes
  and traffic modes
• At least 80 should be content with the traffic
  information given

10
EXISTING CONDITIONS

• 24 entry ramps on 17 km, some with heavy exchange
  of traffic
• 40 bridges (crossing roads, paths, railways,
  streams)
• AADT between 50.000 82.000
• Capacity fully utilized in the peek hour

11
Average number of minutes on a weekday in year
2000, with speed below 40 km/h
12
EXECUTION OF THE ROAD CONSTRUCTION

• Road construction will be in progress along the
  whole stretch in 4 years
• The traffic will be handled in 2 narrow lanes in
  each direction no hard shoulder
• Safety fences will
• create tunneleffect

13
Bridges to be replaced, rebuild or widened

DECISION PROCESSFOR ITS
15
ANALYSIS OF TRAFFIC PROBLEMS

• Acceleration and deceleration lanes
• Traffic flow
• Transferred traffic to other roads
• Incidents

16
ACCELERATION AND DECELERATION LANES

• Limited length of acceleration and deceleration
  lanes have an unfavourable influence on traffic
  flow
• Distance between lanes is 1 1,5 km
• Advantageous to limit the number of open lanes

17
TRANSFERRED TRAFFIC

• The OTM traffic model was used to determine the
  consequences of reduced capacity and speed on
  Motorring 3
• 30 of the road users will use other routes
  primarily parallel routes (ring roads)
• Appr. 60 of the road users on Motorring 3 are
  local.
• Appr. 25 passes through the hole stretch

18
Primary alternative routes ring road (02), 03
and 04 Tårnvej-connection
19
INCIDENTS

• Incidents in the peek hours will have a heavy
  influence on the traffic flow
• Today there is one daily incident on the stretch
  - from this 1 accident a week
• The number of incidents are expected to increase
  due to reduced traffic flow and congestion
• The bridge and ramp construction works will
  complicate the driving conditions

DECISION PROCESSFOR ITS
21
NEEDS ANALYSIS

• Needs for ITS contra traditional traffic
  management, i.e.
• Flexible solutions
• Dynamic information and control
• Real-time data and information

22
DECISION PROCESSFOR ITS
23
ASSESSMENT OF THE ITS SOLUTION

• Needed functionality
• Experience from other applications
• Evaluation of technical performance and drivers
  behaviour and opinions
• Other outside circumstances

24
DECISION PROCESSFOR ITS
25
PROPOSAL FOR SOLUTIONS

• Functional description and expected effects
• Priority of solutions in relation to success
  criteria and traffic problems
• Budget

26
PROPOSAL FOR MOTORRING 3

• Extensive use of ITS systems
• Traffic control to increase traffic safety and
  achieve a more fluent traffic flow
• Traffic information to offer a good service to
  the road users and to distribute the traffic
  optimally in the available network

27
TRAFFIC CONTROL

• Dynamic speed control on the whole of M3
• Queue warning
• Ramp metering
• Incident management

31
TRAFFIC INFORMATION

• Information pre- trip and on-trip
• VMS on M3 and radial roads delays / travel time
  and special guidance
• Traffic status on M3 and 04 alternative routes
  dynamic maps with real time and prognosis,
  reports in the radio, telephone-service, RDS-TMC
• Information regarding alternative routes
  Traffic-SMS, E-mail service
• Campaigns to influence travel time, transport
  mode and to change road users behaviour
