New type signalized rotary intersections design and computer analysis of the applicability at the important points of Antalya

Studies on performance evaluation in urban transportation systems have made significant progress with the use of mathematical models. Simulation techniques, in addition to creating detailed models, enable the trials to be done in the field much safer, cheaper and faster. Two different original values were examined in this study. Within the scope of the first, the number of vehicles passing through the proposed new type of virtual zone will be counted, through a camera system, using the Otsu threshold determination algorithm and the morphological processes method. And the second one will be explained by making comparisons of the situation occurred in 2016 at a 4-way signal-controlled intersection, with the current situation since 2017 and the situation in the proposed new type signalized rotary intersection, over the traffic analysis, modelling and simulation software Aimsun. Simulations were performed for both proposed new methods in the thesis proposal. The intersection at which the new type vehicle counting and the place of application of the new type intersection will be implemented is the the (Sampi) intersection of the Burhanettin Onat Street and Metin Kasapoglu Street in the borders of Muratpasha district. The first method, the new type of virtual region, was realized with the Matlab program and the comparison results with the existing virtual regions in the literature were given. The virtual zone provided the desired performance. The second method, the new type of intersection design, was designed with Aimsun Next Professional Edition v1.0. Situation in 2016 at Sampi intersection and post 2017 and current situation and new type of signalized rotary intersection situation simulations were realized. In case if the proposed new type of intersection is introduced and applied instead of the existing intersection, the determination of the system performance is implemented, and the results are given comparatively. If the offered new type of virtual zone is applied, vehicle count will be performed with 95% accuracy; in case of being in the incoming lane of the intersection named so in the literature the vehicle count will be performed with 86 accuracy; in case if Virtual Zone will be in the middle of the intersection, the vehicle count will be performed with 90 % accuracy. The proposed new virtual zone reduced the percentage of vehicle missing by at least 5% according to literature methods. With the new type of intersection design, the vehicle intensity is reduced, the number of stopping time of the vehicles passing through intersection the decreases, the delay times of the vehicles at the intersection are less and the fuel consumption in the vehicles has decreased significantly. If traffic safety and the conflict points of the vehicles are evaluated, it was observed that there are 64 conflict points in the intersection type in 2016 year, 54 conflict points at the current intersection after 2017 year, and if the proposed new type of intersection was applied, 44 conflict points occurred to be. It is recognised that the new type of proposed intersection is 20% safer than 2017 and post-2016 year. It was understood that the analysis results obtained for both methods provided the desired performance and could be used for existing intersections with a study to be done.
