There has been much talk in recent weeks about the decision of the municipality of Bologna<\/strong>, that aims to become the first major 30 km\/h city in Italy<\/strong>, with the transformation expected to be completed by 2024. The new traffic plan, called Bologna Citt\u00e0 30, seeks to create calmer, safer, and more livable streets by implementing a maximum speed limit of 30 km\/h on 90% of the perimeter of the most densely populated part of the city.<\/p>\n\n\n\n “The first concept of \u2018Zone 30\u2019 started in the Netherlands in the early 1970s, when a group of parents blocked a whole neighbourhood to demand that no more children die in car crashes\u201d Matteo Dond\u00e9, an Italian architect and urban planner, told Euronews<\/a>. <\/p>\n\n\n\n Cuts in speed limit of up to 50%\u00a0have been introduced In the last two years<\/a>\u00a0in Paris, Brussels, London, Copenhagen and cities across Spain. Grenoble and Edinburgh adopted the same model. And\u00a0over 380 German cities want to make it easier to establish 30 km\/h zones<\/a>. But the list can continue.<\/p>\n\n\n\n This article was published in our newsletter\u00a0Next Stop. Safety is usually mentioned as the top priority<\/strong> (and top achievement) of the 30km\/h limits model.<\/p>\n\n\n\n According to data recently released by Transport for London<\/a>, \u201ccollisions involving a vulnerable road user have decreased by 36\u202fper cent, while collisions resulting in death or serious injury\u202fhave decreased by 25\u202fper cent after\u202fspeed limits were lowered<\/strong>. People hit by a vehicle at\u202f20mph\u202fare around five times less likely to be killed than at 30mph\u201d.<\/p>\n\n\n\n The General Directorate of Traffic (DGT) in Spain<\/a> stated that the probability of dying in a pedestrian accident decreases to 15% when struck at 30 km\/h, compared to 85% at 50 km\/h.<\/p>\n\n\n\n The European Data Journalism Network quotes<\/a> Magdalena Markovic, the press referee of the Graz city council (where a 30 km\/h speed limit has been in force since 1992): she \u201cargues that the biggest advantage of the change is achieving safer transportation in the city. Already in the first two years of the policy, the number of traffic accidents decreased by 25 percent. As there were no other policy changes regarding safe transportation in the same time period, the success is obviously due to the 30 km\/h rule\u201d. However, a study indicates<\/a>: \u201cDo not extend the reduction of the speed from 50 km\/h to 30 km\/h to all streets\u201d. The reason is simple: \u201cA higher speed will help to redirect motor traffic to those areas with less pedestrian traffic and less inhabited<\/strong>\u201d, thus lowering traffic pressure on densely inhabited areas.<\/p>\n\n\n\n The already-mentioned article by European Data Journalism Network notes<\/a> that \u201cNone of the European cities that lowered the speed limit to 30 km\/h regrets it\u201d.<\/p>\n\n\n\n

In Helsinki, \u201cIn places where the speed limit was changed from 40 km\/h to 30 km\/h pedestrian injuries decreased by 19 percent and vehicle damages by 34 percent. The biggest improvement was observed in the city centre, where the number of traffic-related injuries decreased by 42 percent\u201d, still according to information quoted by the European Data Journalism Network.<\/p>\n\n\n\nReasons for 30 km\/h speed limit go far beyond safety<\/h2>\n\n\n\n
