Evaluation of Transit Oriented Development (TOD) with Developing Node-Place Model and Cluster Analysis (Case Study of Mashhad Metro Line 1)

Transit oriented development (TOD) is a strategy for integrating land use and public transportation systems in urban areas around metro and BRT stations. TOD means maximum density, maximum diversity, pedestrian facilities, public spaces around stations, and design of stations as leisure centers within a 10-minute walk of transportation stations. This research was carried out with the aim of clustering 9 stations on line 1 of Mashhad metro, by developing a node-place model in TOD areas and using Ward cluster analysis. The present research is applied-evaluation in terms of purpose and descriptive-analytical and quantitative in terms of nature and method. Data analysis was also performed using Execle and Arc map software. In this study, municipal data were used; And land use information was prepared in the field and entered into Arc map software. To achieve this goal, a circle with a radius of 500 meters was drawn to the center of each station and three indicators of place, node and access were evaluated. In the next step, the scatter diagram of the node-place model was drawn. The stations were clustered by adding access criteria (including IPCA and bicycle route indicators). The results of the node-place diagram show that the average place criterion is higher than the node. The average location is 0.303 and the average node is 0.274. Also, all but one station is in a balanced area. Ward clustering results show; By adding access criteria, the position of the stations in the clusters changes and they are classified into four general categories. Also, the degree of correlation between the two criteria of place and node with positive access. But this number is very low for access and node and r= 0.12 and for access and place r= 0.6. In addition, it can be said that the standard of the node decreases from the city center to the surrounding area. The place criterion is affected by the main intersections and is more in the old neighborhoods of commercial units and population. Accessibility in new neighborhoods has increased due to more intersections and smaller urban blocks.
