  • The Wireless low floor tram uses the energy more effectively than other systems with onboard battery system. But for this the SOC(state of charge) management of the battery system is required. This paper is focused on the SOC management strategy of battery system for propulsion in wireless low floor tram. For minimizing consumption energy, the SOC management strategy that maximizes the regeneration energy is studied. The SOC operating region is divided to overcome the limited life cycle pointed out as a disadvantage of battery system. And the effective energy management strategy of tram is suggested through the charge/discharge of the battery system according to tram status in catenary/catenary-free section.

  • The first tram in korea was commended the operation from 1899 to 1968 as a core role of public transportation. However, tram recently is being recognized as an alternative against a traffic congestion, a super-aged society and an environmental pollution problem. Because of these advantages, we are trying to introduce tram in korea. The efforts to introduce trams have focused on the economic analysis for tram construction. But we must be interested in tram operational safety. Early opening tram accidents could affect a negative impact on the additional tram introduction. We are trying to introduce trams in Daejeon, Wi-Rye and Su-won. In this paper, I want to check the safety issues in tram operation phase.
