The Role of Contemporary Urban Designs in the Conflict Between Vehicle Users and Pedestrians in Iran Cities (Case Study: Hamedan City)

2 Abstract: The morphological survey of the historical fabric in Iran shows that fabric integrity has been one of the most significant characteristics. This integrity resulted in the continuity of travelling paths especially for the pedestrians. The street layout in the new era caused the urban fabric to disintegrate and the pedestrians' movement to interrupt. This is accompanied by the fact that the arrangement systems of uses are remained intact. Currently, pedestrian associating ancient city layout confronts an interrupted anatomy which forces him to violate the law and use the realm of street. This violation increases the conflict between car users and pedestrians leading to damage and injury. One of the cities suffering from this issue is Hamedan. Most of the tourist attractions such as Babataher, Bu-Ali tomb and Imamzadeh Abdullah tomb are located in the middle of the city and have increased the conflict of movement. This paper aims at investigating the factors influencing the increase of conflict between pedestrians and car users such as the velocity of pedestrians' movement, the distance ahead; vision angle and diffraction form the path while passing across the street through survey study. It analyses two factors of vision angle and diffraction from path through recording behavioral maps of pedestrians in some major causes in Hamedan city. The results show that the closer the vision angle between target and source (dependent uses) to diffraction angle from movement path of pedestrian, the greater the conflict between the pedestrian and the car user, as the pedestrian explores for a path to reduce the distance regardless of car users' realm. Finally, there are suggestions to reduce the intervention of these factors in conflict between pedestrian and car user.
