Abstract [en]

Traffic safety is a growing topic that critically impacts urban mobility and public health, demanding innovative and practical solutions to ensure road safety. As vulnerable road users, cyclists face significant road hazards due to exposure and limited physical protection compared to motorized vehicles. This report addresses the safety challenges parents face cycling with their children using electrically assisted bicycles. By utilizing the Fine Time Measurement (FTM) protocol for distance estimation between two microcontrollers, the system enables live monitoring in traffic. The system also incorporates a Kalman filter and tolerance for system bias during measuring. Testing indicated superior accuracy over traditional localization methods in static conditions, though challenges persist in dynamic conditions. 

Abstract [sv]

Denna uppsats fokuserar på att förbättra säkerheten för cyklister genom att utveckla ettrealtidsbaserat lokaliseringssystem som utnyttjar Fine Time Measurement (FTM)-protokollet föratt mäta avstånd mellan två ESP32-mikrokontrollers. Projektet syftar till att möjliggöra merexakt och pålitlig övervakning av barn under cykling, särskilt i potentiellt riskfyllda miljöer därföräldrar behöver snabb information om barnets position. Systemet integrerar Kalman-filter föratt minska mätbrus och förbättra precisionen i dynamiska utomhusmiljöer, med ett särskilt fokuspå att uppnå en noggrannhet på under en meter. Testresultaten visar överlägsen noggrannhetjämfört med traditionella lokaliseringsmetoder i statiska miljöer, även om dynamiska scenarierfortsatt utgör en utmaning.
