The model assumes that travellers decide their departure time to minimize the disutility of shortage stay time at the shopping centre, disutility of lateness home arrival time, and disutility of the flexible daily temporal constraint. It is applied to urban shopping travellers on the basis of their home-shopping, centre-home travel pattern. The model is confirmed by a goodness of fit test. It can be applied to develop a model of travel patterns and chosen in further studies.. |

In China, the school roads are typical of roads with mixed pedestrian and automotive traffic. The roads are narrow, and also have a very high traffic during the start and finish of the school period, which creates a high risk for children. The intent of this paper is to investigate ways of securing the road and guaranteeing the safety of children. In this research we use typical pedestrian's avoidance behavior as an indicator of the dangers to the children and discrete choice model methods of predicting the dangers. Through this model, we quantitatively evaluate the dangers existing in school roads, develop an understanding of microscopic mechanisms of road traffic, and conclude by quantifying and evaluating the possible effects of traffic improvement measures.. |

As well as an urban maintenance is increasingly being undertaken road maintenance and improvements by private sector recently. Thus, the private sector plays an important role in urban renewal and maintenance in urban areas. However, with exception of an urban planning district, road maintenance and improvement projects face several challenges; thus, an overall management plan needs to be implemented, as well as the system of compensation for road maintenance undertaken by the private sector. This paper aims to identify these challenges and discuss the role of city administration in road maintenance, as well as to offer suggestions about the part that the private sector can play in the maintenance of public urban facilities. This study consists of data collection through a literature review, interviews with city administration staff, and a case study of Hanrim Tower in Gwangjin-Gu, Seoul. In conclusion, we suggest how urban maintenance can be managed according to proposals from citizens regarding road maintenance and improvements, and recommend that city administration to set up definite criteria to incentivize enterprises that are willing to carry out the work. Amaintenance of public urban facilities by private sector is particularly focused on road maintenance and improvements, which suggests the need for overall improvements to the urban planning system and the system of incentives.. |

Because more and more fuel and air pollution problems arise recently, an intersection signal control optimization method which aims at reducing vehicle delay, improving capacity is required heavily. This paper proposed a signal control multi-object optimization method to reduce vehicle delay and improve intersection capacity simultaneously at an intersection by using the Genetic Algorithm (GA). Data regarding traffic stream parameters, signal timing details and delay to vehicles are collected from an intersection in Shanghai, Hu Cheng Huan road. The result of the case study shows the optimal timing scheme obtained from this method is better than the observed one.. |

Various factors are calculated to describe the total safe distance headway of main vehicle components. These factors include the driver reaction times, reaction distances, vehicle braking times, and vehicle braking distances corresponding to different water film depths. An excellent match is found between the computed braking distance, the braking time calculated using the proposed numerical model, and the results published in other papers. These calculations are performed to estimate the distance headway and quantitatively analyse the relationships between the speed, density, and water film depth. By using three road-specific parameters estimated by our proposed model, namely, the free-flow speed, jam density, and capacity flow, a link transmission model is developed to analyse the dynamic impact of the water film depth.. |

The shape of the personal space of each pedestrian is regarded as an oval shape, which is composed of four arcs, to precisely quantify movements. Specific models that facilitate the simulation of movement include adjustments to individual speeds based on the proximity of other members, conflict avoidance, overtaking, and direction finding. By implementing these parameters in the simulation, basic data concerning these movement behaviours were collected from the experiment, which was carried out at one a Shanghai subway station. Twenty-four young college students participated in this experiment. Numerical simulation results for a stochastic case under those parameters were obtained. The fundamental diagrams and moving behaviours according to different proportions of ascending and descending pedestrians are analysed and discussed. The results indicate that the simulation platform for personal space can serve as a useful tool to evaluate pedestrian movement on stairs.. |

The isolation yields intense depopulation under aging society in Japan. Improvement of its life surroundings is important challenge for these areas. Some of researches indicate the necessity of the connection to other areas, such as nearby bigger islands or main islands. This study focus on shopping of remote islands residents, especially going out to other areas. This study had a survey in Goto, Nagasaki, and confirmed the resident’s activity to other areas for making up their demand for shopping. Then, to examine the transportation policies and the replacement of shopping facilities, this study built the shopping model that can predict the frequency of shopping in other islands in relation to transportation parameters like travel time. The model showed the good fitness for shopping behavior of residents in Goto.. |

Habitants are usually under poor transportation condition. One of the way to solve this problem is to improve the transportation service. Under this poor situation, it often seems that habitants combine two or three activities in a day. The purpose of this study is to know how people choose their activities, depending on given transportation service. This study pick up two activities of regular medical treatment and shopping that are main purpose of daily trip for elderly person in these place, and made a model for people's behavior when choosing their activity time and activity pattern. Then, we calibrated this model to observed depopulated place, and got a good fitness.. |

In further, the paper take into account the constraint to develop a choice model of leave time from shopping place. The model is derived from minimization of three types of disutility that available during a traveler stays at shopping place and arrives at a destination place, i.e., disutility of shortage stay time at the place, disutility of lateness leave time from shopping place, and disutility of the time constraint as consequence of availability of the temporal constraint during period time of a set origin-destination trip. In order to estimate parameters values of the model, a trial and error process method based on simulation approach was applied. The model was applied to the two categories of shopping centre visitors i.e., car user and motorcycle user categories respectively. By using a goodness of fit test, the proposed model was acceptable. The parameters values show that response of the car users to start the praying activity is later than the motorcycle users. In contrary, durations of the motorcycle users to conduct the constraint activity are later or longer than the car user category. The flexible temporal constraint also can be applied to develop a departure time, trip pattern and mode choice model in further studies.. |

The choice model assumes that traveler’s decision to the both travel problem is determined at the same time and due to minimize the total disutility of three kinds of disutility. The three include disutility of shortage stay time at shopping place, disutility of lateness home arrival time, and disutility that consider the praying time constraint. The model was applied to the individuals who are living in a residential area and have been conducting shopping centre travel. Mostly they have to choose their departure time and trip pattern for the travel at the same time in a certain time frame, where they should conduct a praying time-activity as Islamic society. By taking a goodness of fit test, the proposed model was acceptable. The model can be applied to develop a model of travel mode choice in further studies.. |

The estimation is based on the relationships "between the life-saving rate and the EMS (Emergency Medical Service) transportation time" and "between the over-65 ratio and the number of critical care patients per 10,000," derived from the statistics of emergency medical care records and emergency transportation records. The research could open the door to solve the struggle that some significant determinants of the road evaluation are deliberately ignored.. |

However, it is often the case that no drastic review has been made about station squares. What is required from station squares in the future to improve the convenience of railway services and at the same time solve problems in fulfilling their functions as a transportation node? In this paper, methods of station square development are discussed from a practical and broad perspective, as well as in connection with the advanced development of station areas and the development of their surrounding districts. In the process, we refer to a development approach that incorporates an urban square function into the station square and also take the development of Hakata Station as an example.. |

A couple of them are big ones such as Haneda (Tokyo), Itami and Kansai (Osaka) that are located in or around big cities. Other airports, many of them that are local airports are in middle or small scale cities. In case of connecting to the airport in big city, they are able to have large demand of trip. But in case of connecting to one in small cities, they probably are not expected to have large demand. In addition, the presence of high speed rail accelerates the reduction of demand for flight. In this paper, some policies for the promotion of using local airport are examined, especially trip from local airport to another local one. We already had proposed the long trip model for business travelers in which people decides their depart time and mode. We used it to examine the policies and situations such as frequency, fare, access time to the airport.. |

Based on a method in which individual difference is expressed as probability distribution and a limitation of human faculty to discriminate something is reflected by a threshold value, pedestrian-traffic assignment model different from existing models is proposed. According to the results of some hypothetic simulations, it is found that the improvement of pedestrian environments helps induce pedestrians to choose the area where a planner intends them to flow.. |

Based on commuters' responses to the explicit temporal constraints, a decision model of work arrival time and departure is proposed and calibrated. Then the proposed model in temporal domain was extended to model the choice behavior of P&R mode and private car with consideration of riding time, parking cost and transfer resistance. Furthermore, the modal choice model was applied to predict the effects of parking cost in promoting P&R measure.. |
