Mapping Accessibility in the Historic Urban Center of Bucharest for Earthquake Hazard Response

Abstract

Abstract. Planning for post-disaster accessibility is essential in providing emergency and other services to protect life and property in the impacted areas in the aftermath of such events. Careful planning is especially critical in congested historic districts where narrow streets and at-risk structures are more common or prevail. One of the more common methods of measuring accessibility, the use of isochrones, may be particularly inappropriate in congested historic areas. Bucharest, Romania, is a city with such an older historic core of buildings and narrower streets. examination of simulated accessibility for central Bucharest through the use of mapping and GIS technologies. The finding is that accessibility will be substantially compromised by anticipated building collapse. Therefore, policy makers and planners need to more fully understand and appreciate the serious implications of this compromised accessibility in planning for emergency services and disaster recovery activities.

Divergent patterns of built-up urban space growth following post-socialist changes

“…Centralised governments had promoted the idea that industrialisation must be considered as a key element in defining urban development policy in general (Enyedi, 1992). It is important to note that post-socialist cities in general and Bucharest in particular have not experienced a gradual post-industrial phase, but rather one much foreshortened by rapid economic changes across the globe at the end of the 20th and beginning of the 21st centuries (Ianoş, 2004).…”

Spatial-Temporal Analysis of Land Cover and Use Changes Using Gis Tools. Case Study Băneasa Neighborhood, Bucharest

“…Heat Map dynamic method is used to view the distribution of data in a particular area. Kernel Density Estimation has increasingly been used to examine the spatial distribution and frequency of land use (Scăunaș, Merciu, 2016;Bonnier et al, 2019;Merciu et al, 2018). Kernel Density Estimation is a useful method to investigate the density calculation and representation of spatially and temporally highly dynamic point data sets (Krisp, Peters, 2011).…”

“…Also important are the social valences of the green spaces as recreational areas, places for practising sports, as well as the aesthetic-environmental valences (Chiriac et al, 2009). At the same time, land use and land cover change generate alteration of the cultural landscapes (Merciu et al, 2018;Petrișor, Petrișor, 2018) by eliminating landscape elements or even deteriorating them (Merciu et al, 2015;Schulp et al, 2019).…”

Network-risk: an open GIS toolbox for estimating the implications of transportation network damage due to natural hazards, tested for Bucharest, Romania

“…In any transportation network analysis, the interconnectivity between systems and with other networks should also be considered. In the post-disaster reaction phase, especially road networks prove to be very important (Jenelius and Mattsson, 2015), since they link almost all destinations; in some cases other transportation networks can be also relevant, namely railways, maritime or aerial networks. Communication networks are critical in all disaster cycle phases.…”

“…In the last 2 decades, significant progress has been achieved in transportation network vulnerability and risk analysisnot just at the structural level but also at the functional level. For a comprehensive review, we recommend the studies of Jenelius and Mattsson (2015), Miller (2014), Tesfamariam and Goda (2013), Franchin et al (2011) in the framework of the Syner-G Project, or Kiremidjian et al (2007). These studies reveal that the fundamental steps in evaluating the seismic risk of transportation networks are as follows.…”
