We present a constraint programming formulation for the elevator trip origin-destination matrix estimation problem, and propose different approaches to solve the problem. An elevator trip consists of successive stops in one direction of travel with passengers inside the elevator. It can be defined as a directed network, where the nodes correspond to the stops on the trip, and the arcs to the po...
A new mechanism for the primary photoinduced charge separation in photosynthesis is proposed. It involves as real intermediate between the excited special pair state P * and the primary charge separated state P + H − L a trip-trip-singlet P T B T L , which consists of a triplet on the dimer P and a further triplet on the monomer B L. Both combine to a singlet. The electron transfer is caused by...
Fishers’ trip choice behavior in Hawaii’s longline fishery was analyzed by applying a utility theoretic mixed model (a combination of the conditional and multinomial logit (unordered) models) which accounts for both choiceand individual-specific attributes. The results indicate that fishers demonstrated utility maximizing and risk-averse behavior. They exhibited ‘inertia’ in switching to altern...
the conventional intervening opportunity model which is potentially a powerful analytical and probabilistic model, has been used in transportation planning to model trip distribution pattern. this model is basically suffering from two main limitations. these limitations are the assumptions that trip makers are fully aware of all available opportunities in the area and their trip lengths to all ...
Trip distribution is the second important stage in the 4-step travel demand forecasting. The purpose of the trip distribution forecasting is to estimates the trip linkages or interactions between traffic zones for trip makers. The problem of trip distribution is of non-linear nature and Neural Networks (NN) are well suited for addressing the non-linear problems. This fact supports the use of ar...
extractthe fetal as a passenger that her/his trip takes nine months. accidents and incidents may cause this trip will remain incomplete or to create different effects. islamic authors believe these accidents and incidents not only affected fetal but also affected on all of mental and physical aspects of fetal ' s mather, because fetal is such a part of her body. as good nutrition in mother...
This paper discusses the development of an afternoon peak period trip generation model for both work and non-work trips. Three data sources are used in model development, a Household Travel Survey, a Census-Update Survey, and a Trip Generation Study. Seven one-direction trip purposes are defined, specifically accounting for stops made on the return trip from work to home. Trips are classified b...
Convenience markets with gasoline pumps have flourished throughout the United States in the past 10 years. The growing demand for self-service gasoline and convenience grocery goods, readily accessible with fast service, have fueled a boom in the convenience market business. As transportation engineers and planners, we are asked to determine the impacts of developments on the transportation sys...
A trip-let is an object as shown on the cover of Hofstadter’s book Gödel, Escher, Bach: a solid, threedimensional object that, when viewed from three orthogonal directions, shows three different letters. In this paper we consider two problems related to the construction of such objects for a given set of three letters. First, we want to know whether the silhouettes of the object correspond to t...
As more and more travelers wish to create their personalised trip itineraries, the provision of geographical information and services on travel websites is an unavoidable necessity. The evolution of geoportals, geocollaborative portals and web 2.0 present numerous opportunities and services for making the trip planning process less complex and time consuming, more efficient and more social and ...
