Multi-criteria analysis for major road infrastructure projects. Case study: Brașov – Bacău Highway

Abstract

Road infrastructure projects have proven to be a challenging task, particularly in a dynamic setting, such as mountains and hillsides. Such an endeavour entails the integration and processing of cross-disciplinary research, particularly engineering and geosciences. Our study is oriented towards the geographic aspects, specifically the ones involving applied geomorphology. We aim to provide a cartographic solution that reveals the areas suitable for developing a road network, based on a geomorphologic and environmental approach. This is achieved through a GIS-based multi-criteria analysis involving raster data sets of different geodynamic factors, such as geology, pedology, gravitational processes, land use and other environmental components.

Cost-suitability land modeling for current and proposed transport infrastructure along Timiș-Cerna Corridor (Romania)

“…The suitability factors generally refer to lithology, topography parameters such as elevation or slope angle and the current land use, complemented in some cases with features related to hydrological or geomorphological risks (Pu et al, 2021). In Romania, various assessments of land suitability for the development of transport infrastructure were conducted along the Prahova Corridor (Dobre, 2011;Dobre, 2016), in Ţara Bârsei (Purcăreață et al, 2015) and for the Brașov-Bacău expressway route (Paunescu et al, 2019). The main geographic factors of interest are related to lithology, slope inclination and land use, enhanced with aspects related to soil characteristics.…”

GIS as a Support Tool for Sensitivity and Decision-Making Analysis for Transport Infrastructure Development

“…Furthermore, the study tries to create a new methodology in objectively establishing and evaluating the analysis criteria, which would provide substantiated physical-geographical and socioeconomic solutions. This can be applied to all geomorphotechnical assessments regarding transport infrastructure (road or rail) in order to refine the results by identifying optimal transport corridors in accordance with other environmental elements (Dobre et al 2011, Păunescu et al 2019, Schweikert et al 2014, Jiang et al 2015.…”
