Table 9: Results of the distance to the FPS by alternative. The intelligent pedestrian environment system (CC\({}_{\text{i}}\): 0.64) ranked fifth, and the IoT automatic situation recognition system (CC\({}_{\text{i}}\): 0.57) ranked sixth. These technology elements were considered important after CCTV systems; they are easy to install and operate locally and provide visually differentiated services. By contrast, smart street lights combined with various IoT sensors and lighting technologies (CC\({}_{\text{i}}\): 0.51) ranked ninth, which was evaluated relatively poorly. The results seem to reflect some concerns that the integration and operation of IoT services for crime prevention would increase the number of management points and result in some negligence in managing smart street light infrastructure. Attempts must be made to improve cost-effectiveness and automated management. Mobile crime prevention app (CC\({}_{\text{i}}\): 0.51) ranked eighth. The respondents seem to consider that even though a growing number of municipalities operate mobile-based safe return home services, only outdoor mobile location services can be available and operational. Indoor spatial information must be established to precisely identify indoor locations based on users' mobile devices; thus, it is still difficult to widely use such services in terms of budget and management. Except for the top elements (ranked first to fourth), which are underlying infrastructure solutions, the elements ranked fifth to eighth are considered to be the service elements highly valued as personal safety services.
