3. 2. Implementation of Citizens’ Observations in Urban Pluvial Flood Modelling

   Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

   Författare :Fredrik Schück; [2021]
   Nyckelord :Calibration; Crowdsourcing; Citizen science; CDS-rainfall; 2D flood model; Spatial variability;

   Sammanfattning : Damages caused by urban pluvial floods are believed to increase due to climate change and urbanization as more citizens are impacted in densely populated cities and extreme rainfalls occur more frequently with higher intensities. To prepare cities for these calamities, urban pluvial flood models are created to provide knowledge about how an extreme rainfall event could inundate the studied city. LÄS MER

4. 3. Towards Integrating Crowdsourced and Official Traffic Data : A study on the integration of data from Waze in traffic management in Stockholm, Sweden

   Master-uppsats, Uppsala universitet/Informationssystem

   Författare :Isak Eriksson; [2019]
   Nyckelord :Traffic Management Systems; Swedish Transport Administration; Waze; Crowdsourcing; Data Integration;

   Sammanfattning : Modern traffic management systems often rely on static technologies, such as sensors and CCTV-cameras, in the gathering of data regarding the current traffic situation. Recent reports have shown that this method can result in a lack of coverage in Stockholm, Sweden. LÄS MER

5. 4. The Spatial Pattern of the Fear of Crime in Lund City among Lund University Students: Mapping with a Web-Based Support System

   Master-uppsats, Lunds universitet/Institutionen för kulturgeografi och ekonomisk geografi

   Författare :Jianxiong Li; [2019]
   Nyckelord :fear of crime; sketch map; neogeography; Lund; crowdsourcing; Social Sciences;

   Sammanfattning : The fear of crime is a negative emotional reaction of people to possible crimes, and there is sometimes a disparity between the actual crime rate and the fear of crime of people. Geographical researchers often combine the sketch map with the fear of crime to analyze the spatial pattern of the fear. LÄS MER

7. 5. Crowdsourced traffic information in traffic management : Evaluation of traffic information from Waze

   Master-uppsats, KTH/Transportplanering, ekonomi och teknik

   Författare :Zsolt Lenkei; [2018]
   Nyckelord :Traffic incident management; Traffic monitoring; Traffic incident detection; Spatial crowdsourcing; Waze;

   Sammanfattning : The early observation and elimination of non-recurring incidents is a crucial task in traffic management. The performance of the conventional incident detection methods (traffic cameras and other sensory technologies) is limited and there are still challenges in obtaining an accurate picture of the traffic conditions in real time.
