Investigating the effect of physical-spatial structure on the distribution of travel and urban traffic A Case Study the Rasht City

The spatial and physical structure of the city has an important role in the social functions and behaviors of citizens. Land use as the starting and ending point of the trip is one of the most important factors in creating movement in the city. Intermediate passages are those that are not necessarily the origin or the destination, but must be crossed to reach the destination. How these spaces are chosen by people to reach the destination is explained using the space syntax method. This research is of applied type and the research method is based on examining the significant relationship between spatial-physical factors including land use and syntactic variables (spatial arrangement) with observational factors including the volume of trips in urban areas. In this study, based on the theory of "space syntax" and its concept in the form of "natural motion" in urban space, after examining the spatial-physical structure of Rasht city in three basic steps, using graph analysis of syntactic parameters (integration, connectivity, control, and mean depth) as well as multiple regression method in SPSS software, it was found that spatial syntax and land use layout has a significant direct relationship with citizens' travel behavior and up to 75% of its changes can be predicted. Meanwhile, the beta coefficient of the Space Syntax is 0.63, which is higher than the land use with a coefficient of 0.34. Considering the essential role of physical and spatial characteristics in urban traffic the development of transportation systems can be targeted by developing favorable policies in this field, while identifying the origin and destination of trips and high-traffic routes. And plan to improve the pattern of urban travel and the integration of transportation systems with an emphasis on public transportation and walking.
