Web Site Life Cycle

Image
Web Site Life Cycle The developer of a well-engineered Web site should prepare a project plan, or follow an existing plan, cover- ing the entire life cycle of the well-engineered Web site, including development, maintenance, and retire- ment. The well-engineered Web site project plan shall incorporate consideration of the implications of both minimum and maximum Web site life expectancies. The project plan should address Web site maintainability. The plan should address requirements for dates (see 7.4) and contact information (see 4.2.6 for privacy, 5.7 for Webmaster, and 5.11 for site center). Some well-engineered Web pages have as a significant objective the delivery of specific information to indi- viduals who need that information. Well-engineered Web sites shall have an identified set of metrics that can be evaluated. Ease of access to information by targeted-user communities is an example of one of the possi- ble design goals. 17 Navigation aids, buttons, user readable body met

Analysis of Taxi Drivers

Analysis of Taxi Drivers A battle between two Chinese taxi booking mobile apps, namely, Didi and Kuaidadi, had recently occurred in early 2014. These two apps, which are backed by Internet giants Tencent and Alipay, gave promotion fees to taxi drivers for each deal made and also allowed each taxi passenger to save some money, when a customer had taken a taxi through the app and paid the fare through the mobile payment method. As expected, the taxi service pattern had been greatly changed during this battle. To address the debates on social justice, equity, and improvements of taxi service, we collect 37-day trip data of over 9000 taxis in Beijing to study the influence of this pattern change. In the first 18 days, the battle had not occurred and in the remaining 19 days, the battle is white-hot. We quantitatively demonstrate how several important service indices (e.g., the traveling distances and idle time lengths) of taxi drivers h

Taxi GPS traces

Taxi GPS traces  Taxi GPS traces are valuable resources to investigate taxi drivers’ service behaviors. In this paper, we have studied the taxi drivers’ service strategies based on the activities of thou- sands of taxi drivers revealed in a real-life large-scale taxi GPS data set collected from 7600 taxis in Hangzhou, aiming to provide useful guidance to taxi drivers. To understand the behaviors of a taxi driver, we first propose to separate the taxi GPS traces of each pair of shared taxi drivers based on two observations: 1) The shift handover location and time are more or less fixed on most days; 2) the taxi generally stops for a while in the shift handover location and shift handover time slot for handover, with vacant status before and after the shift handover event. We then convert each taxi delivery distance into corresponding taxi revenue in each time slot and find that most of the taxi drivers do not perform consist
