Outline of Final Research Achievements

In this research, the safety assistance system that performs positioning for pedestrians in the crossings using UWB（Ultra Wide Band) communication and transmits the collected position information to the vehicles entering the crossing using the dedicated short range communication (DSRC) is proposed and the schemes to improve the accuracy of positioning for pedestrians are studied. By performing optimization of positioning algorithm, it was confirmed that the positioning error caused by multi-path propagation is reduced and simultaneous and precise tracking of many pedestrians can be achieved by the proposed scheme.
