(事前公開アブストラクト) In order to progress the advanced driver assistance systems, it is necessary to build Dynamic Map (DM) with low delay data transmission and share it with each vehicle. An important issue is the increase of the transmission delay when the amount of transmitting DM data increases in heavy car-traffic. In this study, we try to reduce the transmission delay by using Mobile Edge Computing (MEC). In particular, we investigate the transmission delay performances of data sharing methods using the MEC server for DM data by simulation.
