  1. Measure 28 Noise Reduction 13.6.2012 Katerina Oktabcova Usti nad Labem Municipality

  2. 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

  3. 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

  6. 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.)

  8. CURRENT STATE

  9. COMPLEX OF BYPASSES

  10. SPEED REDUCTION BY 10%

  11. ELIMINATION OF FREIGHT VEHICLES

  12. 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.

  13. Budget and costs • No implementation • Subcontract: • Development of the city noise map • Budget 17 000€ • Actual costs 17 244€

  14. 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)
