Abstract: (475 Views)
Iran's geographical location, coupled with its unique political, seismic, physical, and demographic conditions, has placed the metropolis of Tehran in a vulnerable position during an earthquake crisis. Assessing the transportation network and distribution of urban open spaces plays a crucial role in emergency evacuation and reducing urban vulnerability. The primary objective of this research is to evaluate and analyze accessibility to these spaces to mitigate vulnerability during earthquakes. Initially, open spaces were identified, and population concentration points were determined using hot and cold spot analysis. Subsequently, the spatial pattern of population points was identified using the nearest neighbor average technique, and their distances from open spaces were calculated. The results indicate that open spaces are more abundant than semi-open spaces and are primarily located in the northern parts of the region. Additionally, population density is high in the center of the region and low in the eastern parts. On average, the distance between population concentration points and open and semi-open spaces is 300 and 400 meters, respectively. Service area analysis reveals that access to open spaces is possible within 15 to 300 seconds, but access is limited in some western areas. Access to semi-open spaces is unsatisfactory, and in parts of the north, west, and east of the region, access will not be possible. Overall, in the event of an earthquake, except for parts of the western and eastern edges, there is adequate access to safe spaces within the specified time frame.
