Wissam Qassim Al-Salih, D. Esztergár-Kiss
Dealing with the present congestion and creating sustainable transport systems has been the greatest challenge of urban transport planning. As transportation activities affect environmental quality, knowledge, why travellers prefer specific modes can help a region do judicious transportation planning. The travellers' daily trip and mode choice process have mainly involved three types of choice: mode choice, time choice, and route choice. In this paper, we focus on studying the impact of the activity characteristics that include activity purpose and the characteristics of the individuals, such as gender, age and income, and average distance of the trip, on the transport mode choice for completing activities of travellers. The aim is to use statistical analysis to investigate the impact of these variables on transport mode choice applying the decision tree model, which provides a set of easy-to-interpret decision rules necessary to make appropriate decisions. The data processing in this study is based on actual observations of travel behaviour in Budapest. Our analysis's findings indicate that income, distance, and activity purpose are the most significant factors in the decisions related to mode choice. Also, this study provides promising insights for developing activity chain modelling.
解决当前的交通拥堵问题,建立可持续的交通系统,一直是城市交通规划面临的最大挑战。由于交通活动影响环境质量,了解旅行者为什么喜欢特定的交通方式可以帮助一个地区做出明智的交通规划。旅行者的日常出行和方式选择过程主要涉及三种类型的选择:方式选择、时间选择和路线选择。本文重点研究了包括活动目的在内的活动特征和个体的性别、年龄、收入、平均出行距离等特征对出行者完成活动的交通方式选择的影响。目的是使用统计分析来研究这些变量对运输方式选择的影响,并应用决策树模型,该模型提供了一组易于解释的决策规则,以做出适当的决策。本研究中的数据处理是基于对布达佩斯旅行行为的实际观察。我们的分析结果表明,收入、距离和活动目的是与模式选择相关的决策中最重要的因素。此外,本研究为开发活动链模型提供了有希望的见解。

Maria Rona Perez, Danna May Manssul, Rossana Adao, Eymard Pempina, A. Lagman, Melba Besa
Crafting a good digital experience for children can be difficult; game designers have to consider children's cognitive and motor skill limitations, understand their target audience, create something entertaining and educational at the same time. This should also comply with national and international jurisdiction, and time appeal to parents as well. In this paper the researchers used of an educational game called Tahderiyyah Literacy App (TLA) with standard general framework which designers and developers created for children ages four to six years old. This platform has been the testing ground for the edutainment game in the field of user experience. The purpose of the paper is to observe the interactions, experience and adaptation of kindergarten pupil (learners) on a particular on the TLA based on game's user experience. TLA was design using their mother tongue which can be played on mobile devices. Focusing only to learners from Muslim Community. While the term User Experience encompasses both physical and digital experiences, the main focus for the framework is purely for digital services wherein only touch based devices are evaluated in greater detail. On the assessment process, students were observed and interviewed about the game and what they learned about numbers and letters from game they played. This process was done to help the kindergarten answers their questionnaires. Every learner that act as respondents were guided to answer the answer the questionnaires given to them. Results of using TLA to analyze an HCI factors in learning environment are described in the later part of this paper. Implications for using TLA as a design for pedagogical tool are also discussed.
为孩子们打造良好的数字体验可能很困难;游戏设计师必须考虑儿童的认知和运动技能限制,了解他们的目标用户,同时创造一些娱乐性和教育性的内容。这也应该符合国家和国际的管辖权,同时也要吸引父母。在本文中,研究人员使用了一款名为Tahderiyyah Literacy App (TLA)的教育游戏,该游戏具有标准的通用框架,是设计师和开发者为4至6岁的儿童创建的。这个平台一直是寓教于乐游戏在用户体验领域的试验场。本研究的目的是观察幼儿园小学生(学习者)在一个特定的基于游戏用户体验的TLA上的互动、体验和适应。TLA是用他们的母语设计的,可以在移动设备上播放。只关注来自穆斯林社区的学习者。虽然“用户体验”一词既包括物理体验,也包括数字体验,但该框架的主要关注点纯粹是数字服务,其中只对基于触摸的设备进行更详细的评估。在评估过程中,学生们被观察和采访关于游戏以及他们从游戏中学到的数字和字母。这个过程是为了帮助幼儿园回答他们的问卷。每一个作为应答者的学习者都被引导去回答给他们的问卷的答案。本文的后半部分描述了使用TLA分析学习环境中HCI因素的结果。本文还讨论了使用TLA作为教学工具设计的意义。

Autonomous Vehicles Preference Study with the consideration of Motorcyclists in Taiwan 台湾地区摩托车使用者对自动驾驶汽车偏好之研究
Li-Wen Chen, Chuan Chuang
Utilizing information and communication technologies (ICT) for the smart city is considered as a management strategy for growing population and rapid urbanization situation. Autonomous vehicles (AVs) will play a role to improve road safety, relieve congestion, save energy, and reduce air pollution. Moreover, it would be also a solution to solve the first mile and last-mile problem in transportation. Shared autonomous vehicle (SAV) is a service for public transportation, or paratransit system. Once SAV service is applied in an urban city, the new mode will have new interactions with existing modes. Besides, an emerging technology breakthrough is accompanied by user adoption and reliability. This paper proposes a demand-supply conceptual framework for studying the possible operations of SAVs. The demand side is modeled through multinomial logit models (MNL) based on a survey. The MNL is used to analyze travelers' preferences for SAVs and Biogeme software to estimate parameters. The results show that SAV is more likely to be used by people who use public transit frequently, have a ride-sharing experience, and are female.
利用信息通信技术(ICT)建设智慧城市被认为是应对人口增长和快速城市化形势的一种管理策略。自动驾驶汽车(AVs)将在改善道路安全、缓解拥堵、节约能源和减少空气污染方面发挥作用。此外,这也将是解决交通中的第一英里和最后一英里问题的一个解决方案。共享自动驾驶汽车(SAV)是一种公共交通服务,或称辅助交通系统。一旦SAV服务在城市中应用,新模式将与现有模式产生新的交互。此外,新兴的技术突破伴随着用户的采用和可靠性。本文提出了一个研究sav可能运作的需求-供给概念框架。在调研的基础上,通过多项logit模型(MNL)对需求侧进行建模。MNL用于分析旅行者对sav的偏好,并使用Biogeme软件来估计参数。结果表明,SAV更有可能被经常使用公共交通、有拼车经历的人使用,而且是女性。

Shuqin Zhang, Wei Jiang, N. Yang, Bing Long, Jianan Zhu, Yi Zhou
Based on time elasticity definitions for passengers, ground staff and crew, we propose one evaluation method, which screens out airport ground service process with the maximum time elasticity for transit flight, to reduce arrival time of passengers at airports, increase the flexibility of ground services and improve the connectivity between arrivals and departures for crew. Firstly, timed delay Petri net is used to elicit all feasible service processes of one transit flight, and then the optimal service process is obtained by Analytic Hierarchy Process and fuzzy comprehensive evaluation method. Finally, one concrete example results show that the method can obtain time elasticity ranking of all feasible service processes which demonstrates its effectiveness.

Research on Layered Planning of Tourism Bus Network Based on TOD Concepte: A Case of the Tourism Bus of Guilin City 基于TOD概念的旅游巴士网络分层规划研究——以桂林市旅游巴士为例
Z. Song, Dehui Gao, P. Chen, Yuehan Cao
At present, tourist buses are mostly a single mode connecting scenic spots. How to build a multi-level tourist bus system that serves world-class tourist cities is worthy of attention. Based on the concept of TOD, this paper innovatively proposes methods to evaluate the TOD index of tourism and to plan the tourism bus network hierarchically. First of all, this paper constructs a tourism TOD index from three perspectives: the service level around the tourist intention point, the development potential around the tourist intention point, and the traffic convenience near the tourist intention point. In the context of traffic big data, a web spider which is written in Python crawls POI data to realize the quantification of tourism TOD indicators. Then, ArcGIS is used to statistically analyze the tourism TOD index to determine the graded travel demand points of passengers. According to the demand of passenger flow, the multi-level tourist bus network is planned reasonably. Finally, the research results are applied to the tourist bus in Guilin City, which proves that the method has good applicability.

Research on the impact of large vehicles on the safety of short-distance Ro-Ro passenger ships 大型车辆对短途滚装客船安全的影响研究
Wanyu Hu, Zhongzhou Fan, Zhipeng Zhang, Pengfei Jiang
In the short-distance transportation of Ro-Ro passenger ships, the crew takes a short time to secure the vehicle before sailing, and sometimes the vehicle is not effectively secured. In windy weather, the vehicle is prone to slip and capsize, causing the ship to tip over. This article analyzes the five aspects of "ships, crews, large vehicles, natural environment, and navigable environment", and establishes an index system for the safety of short-distance Ro-Ro passenger ships carrying large vehicles; the C-OWA operator weighting method is used to calculate each evaluation index For weight, the asymmetric close degree function is introduced to replace the maximum membership function in the traditional extension theory to solve the problem of the failure of the maximum membership degree, so as to establish an improved matter-element extension model. Taking the Qiongzhou Strait Ro-Ro passenger ship as an example to verify, the navigation safety risk level of the Ro-Ro passenger ship is obtained for the situation that large vehicles are not secured. The research results are basically consistent with the actual situation, verifying the effectiveness and practicability of the improved matter-element extension model for the research on the impact of this type of navigation safety.
在滚装客船的短途运输中,船员在航行前需要很短的时间来固定车辆,有时车辆没有得到有效的固定。在有风的天气,车辆很容易滑倒和倾覆,导致船只倾覆。本文从“船舶、船员、大型车辆、自然环境、通航环境”五个方面进行分析,建立了载运大型车辆的短途滚装客船安全指标体系;采用C-OWA算子加权法计算各评价指标的权重,引入不对称紧密度函数代替传统可拓理论中的最大隶属度函数,解决最大隶属度失效问题,从而建立改进的物元可拓模型。以琼州海峡滚装客船为例进行验证,得到了大型车辆不安全情况下滚装客船的航行安全风险等级。研究结果与实际情况基本一致,验证了改进的物元可拓模型对该类航行安全影响研究的有效性和实用性。

Multi-label Learning By exploiting Correlations of Label Subsets 利用标签子集的相关性进行多标签学习
Liwen Peng, Xiaolin Zhu, Zhang Yun
Multi-label learning studies exist in a wide range of diverse scenes such as text processing, image mining, emotion analysis, etc. Feature selection technologies are proposed to be a vital factor in the scene of multi-label learning, which can relieve the influence of curse of dimensionality, enhance the classification accuracy, and reduce the time of consumption of learning process. At present, a great number of multi-label feature selection algorithms are proposed by the researchers who are focused on the machine learning or other research fields. It is demonstrated that considering the label correlation when the method choices the importance feature subset will improve the multi-label learning methods performance. On this account, a method that based on correlations of label is proposed in this work.
