response: "Response from the Ministry of Infrastructure\nArticle 21 of the Road Act\
  \ (ZCes-1) defines traffic calming devices and measures. Traffic calming devices\
  \ are physical, lighting or other devices and barriers that physically prevent road\
  \ users from driving at speeds higher than the prescribed speed.  Traffic calming\
  \ devices and measures may only be implemented on sections of roads through settlements\
  \ where the desired vehicle speed cannot be ensured by solutions and measures in\
  \ accordance with the road design regulations, or where a significant number of\
  \ speeding vehicles are found to be exceeding the speed limit and, as a consequence,\
  \ an actual or potential risk to the safety of road users is identified. They are\
  \ most often carried out in urban areas, in suburban centres and villages and in\
  \ densely populated suburban neighbourhoods, i.e. mostly where there is a mix of\
  \ motorised and non-motorised traffic. Traffic calming measures can be implemented\
  \ on the road network, on the carriageway itself or through the design of the carriageway.\n\
  The installation of traffic calming devices or measures is mandatory in front of\
  \ educational establishments and other facilities where the specific population\
  \ structure of the users requires a reduction of the speed limit in the settlement.\
  \ Physical traffic calming barriers must be duly justified, i.e. they cannot be\
  \ installed on the basis of the mere wish of nearby residents, but can only be installed\
  \ on the basis of prior analysis (data on a higher proportion of persistent non-compliance\
  \ with the speed limit over a longer period of time, or data on the number of traffic\
  \ accidents, etc...). The decision to implement these measures must be technically\
  \ justified, as must the choice of the type of measure (in practice, it happens\
  \ that residents want a specific measure to be implemented, even though it is not\
  \ technically justified or would not be able to have the desired effect). Traffic\
  \ calming devices and measures on roads are designed in accordance with the Technical\
  \ Specification TSC 03.800:2009 Traffic Calming Devices and Measures, issued as\
  \ a regulation on the basis of the Order on the Compulsory Application of the Technical\
  \ Specification (Official Gazette of the Republic of Slovenia, No 21/00), and the\
  \ Regulation on Traffic Signals and Traffic Equipment on Public Roads (Official\
  \ Gazette of the Republic of Slovenia, No 46/00, 110/06, 49/08, 64/08 and 65/08),\
  \ which prescribes the use of prefabricated physical barriers to calm traffic -\
  \ humps.  Traffic calming measures may be established on the basis of:\n systemic\
  \ measures to regulate traffic for the whole or part of a settlement, with prior\
  \ preparation of the traffic layout; regulatory measures, which are a set of traffic\
  \ rules defined by the Road Traffic Rules Act, i.e. the installation of appropriate\
  \ traffic signs; optical and audible warning devices, whose function is to warn\
  \ drivers that they are approaching a speed limit area; humps and ramps designed\
  \ to force speed reductions. They are one of the more severe traffic calming measures\
  \ and are placed where physical barriers are required to force the driver to reduce\
  \ his speed.     Humps are used on roads in residential areas with low traffic density\
  \ and on roads where there are no regular public passenger transport routes. They\
  \ are prohibited on trunk and regional roads and roads with a longitudinal gradient\
  \ greater than 8%. They are an effective and affordable measure. The disadvantages\
  \ are that they are uncomfortable to drive on, increase noise and air pollution\
  \ through braking, are aesthetically unsuitable, do not allow all types of traffic\
  \ to pass normally, and are a hindrance to road maintenance in winter.     The use\
  \ of pavements is mainly concentrated at junctions with a high concentration of\
  \ pedestrians, at entrances to residential areas and on straight stretches of road.\
  \ They are effective in reducing speeds, improving safety for pedestrians and cyclists.\
  \ The disadvantage is that this solution is relatively expensive - depending on\
  \ the material used, noise increases and, due to braking, air pollution also increases.\
  \ The effectiveness is less than that of humps; narrowing of the carriageway and\
  \ delineation of directional carriageways to reduce traffic speeds and provide new\
  \ areas that can be dedicated to pedestrians and/or cyclists. The narrowing of the\
  \ carriageway has a continuous impact on traffic calming.\nThere is no doubt that\
  \ the basic criteria for determining traffic calming devices and measures are the\
  \ function of the road, the speed at which traffic is travelling and the traffic\
  \ conditions. Additional criteria are the width of the carriageway with roadside\
  \ facilities, the position of the road in space, the structure of vehicles (bus\
  \ and freight traffic), noise pollution, delays for emergency vehicles, road maintenance\
  \ and urban planning conditions.\nEach traffic calming device or measure has its\
  \ advantages and disadvantages. Which of the measures is introduced depends on various\
  \ factors, but it must always be a matter of prior professional judgement. Nevertheless,\
  \ all road users must be aware that safety cannot be ensured by technical solutions\
  \ alone and that safety is a system in which respect for the rules of the road is\
  \ very important.\n "
