The aim of this study was to suggest an enhancement of pedestrian safety through a service design process regarding urban design in new-town area. For this study, the concept, process and touchpoint, and survey design area, of the service design are reviewed as a theoretical study. According to this study, traffic signals, pedestrian environment, pedestrian overpass, and access traffic road were surveyed as touchpoints and a problem search, concept design, design building, institutional implement were analyzed as a service design process. As a result of these studies, the planning method for pedestrian safety based on service design process in terms of the external space design in a new-town area are suggested.

This paper presents a study on the performance analysis on probability of bit error for wavelet in 4-ary SWSK system. The formula for the bit error probability in 4-ary SWSK system was derived from the conventional method. This paper experimentally implements the probability of bit error for Daubechies, Biorthogonal, Coiflet and Symlet wavelet using the conventional formula of bit error probability. Additionally, the performance of bit error probability is analyzed for the period and the number of wavelet taps. Based on the results, we confirmed that the performance of Coiflet and Symlet wavelet for the probability of bit error is superior to the other wavelet, and their probability of bit error are similar.
