Like the previous editions of The Travel and Tropical Medicine Manual, the 4th edition continues to successfully teach the fundamentals of travel and tropical medicine and serve as a useful reference. The manual is wellorganized and literally (measuring 12 × 20 cm) and fi guratively handy. It has many appealing tables and fi gures, a colorful cover, and a reasonable price. It remains appropriat...

We develop a day-to-day route choice control method that is based on model predictive control (MPC). For the route choice we assume that drivers base their decision on the experienced travel times. These travel times can be influenced via existing control measures, e.g. outflow limits or variable speed limits. This allows us to indirectly influence the route choice of the drivers. In previous w...

The flexibility of bus rapid transit (BRT) in scheduling is one of the greatest differences with traditional buses. In order to improve BRT operation quality, the paper studied the headway optimization and scheduling combination of BRT vehicles. A model has been established to minimize passengers’ travel costs and vehicles’ operation cost, and constraints included passenger volume, time, and fr...

The class of k Nearest Neighbor (kNN) queries in spatial networks is extensively studied in the context of numerous applications. In this paper, for the first time we study a generalized form of this problem, called the Time-Dependent k Nearest Neighbor problem (TD-kNN) with which edge-weights are time variable. All existing approaches for kNN search assume that the weight (e.g., travel-time) o...

this study explores identity elements of tehran province in travel writings with concentration on symbols in urban planning and architecture. on one hand, symbolic representation of a city plays a crucial role in identity making and on the other hand special provinces and cities like tehran are important in echoing contemporary iranian national identity and are highly closed to today’s iran. in...

Electric vehicles introduce new problems in vehicle route planning. Due to limited battery capacity the fastest route from origin to destination is not always feasible. Existing techniques compute the energy optimal route, however this route is often too conservative in terms of travel time. Optimizing both energy consumption and travel time may allow us to identify routes which are both fast a...

Introduction: The number of foreign travelers arriving in India has shown an exponential increase from 1.2 million in 1981 to 8.03 million in the year 2015, with an annual growth rate of 4.5%. With the influx of internationally mobile students to developing countries such as India comes the responsibility of having to cater to the health needs of these visitors. The current stu...
