A study published in early 2018 by the Swedish National Road and Transport Research Institute shows the impact of lower speed limits in urban areas on road fatalities and injuries. A maximum speed reduction from 50 to 40 kilometer per hour could help save as many as 5 lives per year and prevent 83 severe injuries and 12 very serious injuries on a yearly basis.
The process of developing policy generally involves research, analysis, consultation and synthesis of information to produce recommendations. Guidelines can help cities develop and assess their transport policies to address existing and new policy objectives. Research organisations and institutions provide valuable data and analysis to underpin policy recommendations and decisions.
