Efficacy of Guiding Signs in Comprehensive Passenger Transport Hub Based on the Uncertainty

Passengers normally need the help of guiding signs when they are transferring in a comprehensive passenger transport hub. The essential function of guiding signs is to induce passengers to quickly select the right route. In this paper, the uncertainty of route choice behavior of passengers, during passengers transferring, was taken as a breakthrough point. By applying entropy function, a method based on the uncertainty was proposed for evaluating the efficacy of guiding signs in the comprehensive passenger transport hub. At last, an example was taken to explain this method which can be easily used to calculate the effectiveness of single sign and streamline.

Design of Mobile Electronic Bus Station Board Based on BPEL

Electronic bus station boards improve service of urban public traffic by offering information of vehicle arrival. However, the users can just query stations and buses they have already known with existed electronic boards. By introducing location-based service a new electronic station board system is designed by which the users are able to query information in a strange environment. The concepts of SOA and BPEL are also adopted for the flexible integration of existed systems such as the GPS Data System and the Traffic Network Information System, which improves the efficiency of development and operation of the new system.

Comparative analysis of mobile application stores in different charging modes

This paper describes the platformisation of the mobile services domain, which in recent years has become a successful strategy for some hardware manufacturers and software companies. While having different platform strategies and business models, they have succeeded in creating a demand for mobile software and content with end-users. This paper proposes a way to determine the optimum platform-charging mode that an operator should adopt to play a meaningful role in the mobile service domain and with respect to content with end-users. Four charging modes employed by mobile application stores are studied in this paper, namely the one-sided paid-by-users charging mode, the one-sided paid-by-advertisers charging mode, the two-sided differential paid charging mode and the two-sided paid and free access charging mode. Furthermore, a comparative analysis of the four modes is also presented.
