• Measure 28
• Noise Reduction
• 13.6.2012

• Usti nad Labem Municipality

Background and Objectives

• Ústí nad Labem has a target to reduce proportion
  of residential areas located in areas exposed to
  traffic noise levels above 65 dB.
• The study has the following goals
• develop the noise map of the city from noise
  generated by the current and predicted traffic
• identify roads with the highest level of noise
• propose measures reducing traffic noise and
  reduce impact of noise for the most affected
  areas
• Assess effectiveness of individual noise reducing
  scenarios

Measure overview

• Tasks
• 11.3.6 Noise Reduction in Ústí nad Labem
• Finished in M19
• RTD task
• Development of a noise map of the city and
  elaboration of a research study of traffic noise
  reduction in the city

4
Task 11.3.6

• Calculation of noise emissions based on
• Hourly traffic volumes
• Type of a road
• Proportion of freight vehicles
• Type of road surface
• Speed of traffic flow
• Longitudinal gradient of a road
• Identified problems
• Model solutions
• Assessment of solutions (transport model)
• Recommendations
• Outputs
• Noise map for the current state and foreseen for
  the year 2025 (day and night)

5
Findings

• Motorway
• the strongest source of noise emissions on the
  road network
• noise can be isolated from residents (distance
  and preventive solutions)
• Local roads
• leading directly through the residential areas
  and by main points of interest (offices,
  businesses, institutions, shopping centers,
  industrial zones etc.)
• its traffic volume is difficult to reduce
• more potential in reducing the transit traffic
  and the freight traffic
•

Assessed noise reducing scenarios

• Zero scenario Current state
• Scenario A Implementing the SE bypass of the
  city
• Scenario B Implementing the SW bypass of the
  city
• Scenario C Implementing the NE bypass of the
  city
• Scenario D Implementing the NW bypass of the
  city
• Scenario E Implementing the complex of city
  bypasses
• Scenario F Decreasing the speed limit in the
  city by 10
• Scenario G Excluding freight vehicles from the
  city

7
Results

• Even smaller reduction by 3 dB requires
  significant decrease of the traffic intensity
  (about 50 ) difficult to achieve in urban
  environment
• Building the complex of city bypasses and
  transferring the traffic from sensitive zones
  shows certain noise reduction
• Speed reduction has a potential to reduce noise
  emissions if implemented in more than 10
• Exclusion of freight vehicles is effective, but
  currently not feasible transfer to other areas
  needs to be assessed
• Recommended to apply other technical and
  organisational solutions
• Appropriate to support the measures by suitable
  demand management strategies for individual
  transport aimed at reducing number of vehicles
  (parking restrictions, paid entrance, etc.)

Recommended solutions for noise reduction

• Greenery, noise walls
• Speed reduction
• Constructional changes on roads
• Traffic calming (speed bumps, narrow roads) and
  partial coverings (tunnels)
• Suitable road surface preventing noise
• Road profile
• Distance from buildings, natural terrain or
  artificial barriers, away from sensitive areas,
  cumulate noise sources, consider topography,
  altitude, ground level, etc.
• Renewal of vehicle fleet
• Avoiding crossroads where possible
• Noise protection for buildings
• insulation, noise resistant windows
• Traffic management
• Improving traffic flow
• ITS, green wave method (avoid breaking and
  acceleration)
• Modifying transport demand
• Preference for non-motorised transport and PT in
  sensitive areas, restrict access, etc.

14
Budget and costs

• No implementation
• Subcontract
• Development of the city noise map
• Budget 17 000
• Actual costs 17 244

15
Evaluation of the 8 scenarios

• Together with the measure 67 Efficient Goods
  Distribution
• Priority measure CBA included
• Operating cost
• Capital cost
• Maintenance cost
• Other assessed indicators
• Noise level and impact (noise map)
• Emissions
• CO, Nox (transport model)
• CO2, Particulate (transport model)
• Goods vehicles moving in the area (transport
  model)
• Construction of the complex of city bypasses
  proved to be the most effective solution in a
  long term (CBA up to the year 2042)
