Development of Nationwide Road Quality Map: Remote Sensing Meets Field Sensing

Abstract: In this study, we measured the in situ international roughness index (IRI) for first-degree roads spanning more than 1300 km in East Azerbaijan Province, Iran, using a quarter car (QC). Since road quality mapping with in situ measurements is a costly and time-consuming task, we also developed new equations for constructing a road quality proxy map (RQPM) using discriminant analysis and multispectral information from high-resolution Sentinel-2 images, which we calibrated using the in situ data on the basis of g… Show more

SAR data from X-band [132][133][134][135], L-band [24,131], and C-band [130] was investigated for pavement roughness estimation. The data were collected using various satellites such as Sentinel-1 [24,130], Sentinel-2 [132], Cosmo-SkyMed [129], and Advanced Land Observing Satellite (ALOS) [131].…”

“…Therefore, identification and zoning of areas sensitive to light pollution in order to assess the environment of these areas seems necessary. Recently, advances in data collection and sharing in many aspects of urban life have provided us with better clues about the characteristics of cities [1][2][3]. In this regard, the effectiveness of remote sensing techniques and data in detecting changes, whether physical or optical changes, has been more than other methods.…”
