Transcript of Off-peak city deliveries - a socioeconomic analysis
Off-peak City DistributionSocio-economic analysis
Sönke Behrends, Chalmers University of Technology
Off-Peak City Distribution - Final Workshop6 December 2016, KTH Royal Institute of Technology, Stockholm
Effect of congestion on emissions
Rigid truck, 18 tons, Diesel Euro VI
Purpose• to estimate the socio-economic effects of off-peak city distribution• travel time benefits for ’common traffic’• emission reduction: benefits for public health and ecosystems• Implications of noise nuisance
• estimate the relative importance of effects• estimate the relative significance of influencing factors
•Transferability of results
Method: Theoretical case study
CUTS Assessment Model
Transport chainsGPS data: project
traffic data: google maps
Emission dataHBEFA (2014)

Sensitivity analysis – Congestion levels
-90% -87% -85%-79% -69% -63%
Martin & Servera 1 (and 2)
• Climate: -25%• Air pollution: -67%• Noise: +158%• No effect on safety
Lidl
• Climate: -3%• Air pollution: -17%• Noise: +160%• No effect on safety
Some general conclusions• Congestion cost dominate externalities •OHD significantly reduce externalities even at moderate congestion levels• Bigger effect on air pollution than on climate impact•No effect on safety
• Benefits at the cost of significantly higher noise impacts• can be mitigated by electrification
