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

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

STRUCTURE OF PRESENTATION

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

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

GATHERING OF NECESSARY INFORMATION

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

Charlotte VithenCoordinator of Traffic Management Traffic Management on Motorring 3

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

Charlotte VithenCoordinator of Traffic Management Traffic Management on Motorring 3

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

Average number of minutes on a weekday in year 2000, with speed below 40 km/h

Charlotte VithenCoordinator of Traffic Management Traffic Management on Motorring 3

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”

ANALYSIS OF TRAFFIC PROBLEMS

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

Charlotte VithenCoordinator of Traffic Management Traffic Management on Motorring 3

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

Charlotte VithenCoordinator of Traffic Management Traffic Management on Motorring 3

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

Charlotte VithenCoordinator of Traffic Management Traffic Management on Motorring 3

Primary alternative routes: ring road (02), 03 and 04 + Tårnvej-connection

Charlotte VithenCoordinator of Traffic Management Traffic Management on Motorring 3

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

Charlotte VithenCoordinator of Traffic Management Traffic Management on Motorring 3

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

Charlotte VithenCoordinator of Traffic Management Traffic Management on Motorring 3

TRAFFIC CONTROL

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

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
