This paper attempts to model stochastic choice behavior in simultaneous trip route and departure time decision-making on road traffic networks, taking into account information quality and individual differences in information interpretation among the population of travelers. Different from the traditional stochastic model, the proposed choice behavior model assumes that road users simultaneously select the trip routes and departure times that have the largest probabilities of incurring the least generalized travel costs. This model is applicable in both static and dynamic settings and can be applied to both ordinary travelers as well as operators of emergent vehicles, e.g., the fire engine. The preliminary numerical experiments show that the proposed stochastic choice model can reflect the overreaction phenomena reported in studies of traffic information provision and the impacts of the types of traffic information on the effectiveness of information provision. This model opens a potential way to analyze network equilibrium behavior taking into account individual differences in the ability of information interpretation as well as information quality.

Amount Of Information

Information retrieval finds itself at an interesting juncture, where the amount of information that is available to people increases every day from its already bewildering limit. The problem is how to get the information we need in a timely and efficient fashion, without delivering useless or unwanted information. Current Web-Based IR systems do their best, but they will find it increasingly. . .

BackgroundCellulitis is a common painful infection of the skin and underlying tissues that recurs in approximately a third of cases. Patients’ ability to recover from cellulitis or prevent recurrence is likely to be influenced by their understanding of the condition.AimTo explore patients’ perceptions of cellulitis and their information needs.MethodMixed methods study comprising semi-structured, face-to-face interviews and cross-sectional survey, recruiting through primary care, secondary care and advertising. Adults aged 18 or over with a history of cellulitis (first or recurrent) were invited to complete a survey, take part in an interview or both. Qualitative data was analysed thematically.ResultsThirty interviews were conducted between August 2016 and July 2017. Qualitative data revealed low prior awareness of cellulitis, uncertainty around diagnosis, concern/surprise at the severity of cellulitis, and perceived insufficient information provision. People were surprised they had never heard of the condition and that they had not received advice or leaflets giving self-care information. Some sought information from the internet and found this bewildering. Two hundred and forty surveys were completed (response rate 17%). These showed that, while most people received information on the treatment of cellulitis (60.0%, n = 144), they reported receiving no information about causes (60.8%, n = 146) or prevention of recurrence (73.3%, n = 176).ConclusionThere is a need for provision of basic information for people with cellulitis, particularly being informed of the name of their condition, how to manage acute episodes, and how to reduce risk of recurrence.
