Modular Innovative Solutions for Smooth and Safe Traffic Flows in the Cities

The city of the future, in terms of traffic safety is represented in the paper that shows the capabilities and utilization of surfaces with conceptual designs and safer transportation and movement of passengers, cyclists and pedestrians. This paper presents four conceptual solutions as an improvement of the alternative form of transportation and movement of cyclists and pedestrians, and by increasing safety, of environmental sustainability as well. The conceptual design presents a bicycle route along the river on both sides, and the bike route on the tram tracks relation; conceptual design of travelator for public transport of passengers; conceptual design of lowering the tram route in the trough by glass covering roof and outside visual communication; covering by domes of pedestrian flows in the area of the Main street and as the fourth, conceptual design in the segment of pedestrian flows by covering the main pedestrian zone with movable transparent roofs. All the solutions have been analyzed in terms of the role and importance of safety and environmental feasibility of the development function of the city and communication of citizens. Solutions of traffic, transport and mobility offered in this paper had not been present in this region and they are not known to the wider areas in the development of the cities and they should serve as an idea for the increasing problems of developing towns in the area with insufficient space for pedestrians and cyclists as well as an offer for bigger and more massive transportation of persons in the urban area. All of the innovative ideas have been conceptually implemented in the form of simulations of the City Sarajevo which has about half a million citizens.
