RSLab (5 Cities): EMBARQ Turkey, we aim to support cities and the government in achieving their ambitious targets by 2020 (Decade of Action Road Safety Plan aims to reduce traffic fatalities by 50% by 2020), build local capacity by emphasizing the importance of data collection and road safety audits in the transport planning phase, and promoting sustainable transport practices that saves lives. EMBARQ Turkey has embarked on a new project, Road Safety Laboratory, to achieve these goals. EMBARQ TURKEY –RSLAB PROJECT

  36. 36. PROBLEM Many vehicles were observed braking in the curve. It was obvious that the curve came as a surprise to drivers.
  37. 37. PROBLEM Most of the accidents occurred right after the curve where the kerb has multiple damage
  38. 38. PROBLEM The curve is signed with a double chevron marker and two single chevron markers. These are not sufficient to warn drivers and to show the alignment of the curve.
  39. 39. The best solution would be to increase the radius of the curve and give it sufficient super elevation but this would be costly and could involve expropriation of land. The only other possibility is to reduce the speed to match the radius and the cross slope. In this case the speed should be reduced to 60km/h. Physical means are necessary to obtain this. As humps are probably too abrupt for this type of road a set of speed cameras could be used instead. Rumble strips could also be considered but they do not seem to be sufficiently efficient in Turkey and they wear out quickly. RECOMMENDATIONS
  40. 40. Pre-warning signs of the speed limit and the curve should be installed. They should be highly reflective and preferably have a fluorescent backing board. In the curve single chevron signs should be placed at short distance along the entire curve. It is also recommended to make no overtaking in the curve by signs and full lane markings supplemented with acoustic lines on both sides. RECOMMENDATIONS
  41. 41. It is assumed that 16 of the accidents will be affected by changing the speed in the curve. We can expect an effect of about 60% on injury accidents. Taking the regression effect into consideration the expected saving in injury accidents will be 8.0 accidents. The total estimated effect is a reduction of 2 injury accidents per year. RESULTS

  44. 44. INVOLVED ROAD USERS
  45. 45. MEVLANA STREET-TRAM PROJECT ALONG THE STREET
  46. 46. Background Mevlana Street is considered the central street of the city centre of Konya. It is lined with historical buildings of great importance. Today the street carries vehicle traffic in two lanes in each direction. Pedestrian traffic is very dense with demands for crossing all along the length of the street. This has led to very high accident numbers. 115 accidents were registered in a five-year period. Given that the length of the street is only 780m the rate of accidents is 30 injury accidents per km per year. A project has now been initiated for establishing a bi-directional tram line in the middle of the street. Construction is ongoing and is scheduled to finish in the middle of 2015. The intension is to keep two lanes for vehicle traffic by allowing car drivers to use the tram lanes except at the station Black Spot-Mevlana Street Audit Challenges
  47. 47. Observation In cities around the world the trend is to make city centres more liveable by reducing car traffic and increasing space for pedestrians and cyclists. This can be combined with good public transport for example by letting trams run in pedestrian streets as the example from Amsterdam in the picture below. Black Spot-Mevlana Street Audit Challenges
  48. 48. It is strongly recommended to consider such a solution for Mevlana Street. Experience from other cities having adapted such a solution shows very positive effects on liveability, turnover of shops along the street and most importantly a significant improvement in road safety. The project opens for a unique opportunity for Konya to upgrade one of its most important historical areas. For example the Kayali Park and the square in front of the Şerafettin Mosque could be joined in a unique city space. If this is not feasible, vehicle traffic should be limited to one lane in each direction, or even better one lane in only one direction. Raised pedestrian crossings placed at every 80-100m should secure that vehicle speeds are kept below 30km/h. It cannot be recommended to let vehicles use the tram lanes. The give-way rules between trams and vehicles will be unclear and drivers may erroneously drive into the station area. Also, allowing driving in the tram line will deteriorate the respect of the tram lanes in other parts of the city. Furthermore, keeping two vehicle lanes in each direction opens for overtaking and with no speed reducing measures will probably lead to the same high accident rates as today.
