Involvement in road traffic crashes as vehicle occupants is a leading cause of death and serious injury among children. The objective of this study was to investigate crash severity factors and child safety restraint use characteristics in order to identify effective countermeasures to increase children＇s highway safety. Characteristics and percentages of restraint use among child passengers aged 4-13 years were examined using highway crash data from Kansas. The association between restraint use, injury severity and characteristics of children involved in crashes were investigated using OR （odds ratios） and a logistic regression model, which was used to identify risk factors. Results showed that children, who were unrestrained, were seated in the front seat, traveling with drunk drivers and on rural roads, and traveling during nighttime was more vulnerable to severe injury in the case of motor vehicle crashes. The most frequent contributing causes related to crashes involving children included driver＇s inattention while driving, failure to yield right-of-way, driving too fast, wet roads and animals in the road. Based on identified critical factors, general countermeasure ideas to improve children＇s traffic safety were suggested, including age-appropriate and size-appropriate seat belt restraints and having children seated in the rear seat. Parents and children must gain better education regarding these safety measures in order to increase child safety on the road.

An Alternative Regression-Based Approach to Estimate the Crash Modification Factors of Multiple Treatments Using Before-and-After Data

引用

Journal of Transportation Technologies 2018年第4期8卷 273-290页

作者： Uditha Galgamuwa sunanda Dissanayake Department of Civil Engineering Kansas State University Manhattan KS USA

Before-and-after methods have been effectively used in the road safety studies to estimate Crash Modification Factors (CMFs) of individual treatments as well as the multiple treatments on roadways. Since the common practice is to apply multiple treatments on road segments, it is important to have a method to estimate CMFs of individual treatment so that the effect of each treatment towards improving the road safety can be identified. Even though there are methods introduced by researchers to combine multiple CMFs or to isolate the safety effectiveness of individual treatment from CMFs developed for multiple treatments, those methods have to be tested before using them. This study considered two multiple treatments namely 1) Safety edge with lane widening 2) Adding 2 ft paved shoulders with shoulder rumble strips and/or asphalt resurfacing. The objectives of this research are to propose a regression-based method to estimate individual CMFs estimate CMFs using before-and-after Empirical Bayes method and compare the results. The results showed that having large sample size gives accurate predictions with smaller standard error and p-values of the considered treatments. Also, results obtained from regression method are similar to the EB method even though the values are not exactly the same. Finally, it was seen that the safety edge treatment reduces crashes by 15% - 25% and adding 2 ft shoulders with rumble strips reduces crashes by 25% - 49%.

Spatial Transformations and Urban Conservation of Religious-Historic Towns: A Case of Vrindavan, India

引用

Journal of Geoscience and Environment Protection 2022年第8期10卷 289-308页

作者： sunanda Kapoor Vandana Sehgal Mayank Mathur School of Architecture & Design Manipal University Jaipur Jaipur India Faculty of Architecture and Planning AKTU Lucknow India School of Planning and Architecture New Delhi India

The spatial transformations can be observed at different religious-historic towns of India due to urbanization. Research is based upon fact that there is substantial change in the built environment because of spatial transformations at the religious-historic towns. The process of modernization in the functions and spatial layout is unavoidable at any historic town. The study attempts to focus on various urban historic conservation components, including the look of historic buildings, their earlier uses, and its immediate surroundings to improve the built environment of historic towns. A theoretical framework for the urban conservation of ancient towns is the main objective of study. How to modernize the historic conservation function while preserving the space’s texture and integrity. The research started with the investigation of the morphological growth of Mathura district, India through satellite images and in-depth study of the evolution process of street network in Vrindavan town, which is one of the main temple towns of Mathura district. There is a significant difference in the layout & architectural character of old part and the newly developed Vrindavan. Due to increased accessibility and movement, the spatial structure of traditional religious precincts, which were once local integration centres, has significantly changed. Increasing & changing mode of transportation and further increase in the religious tourism might be the cause or a big reason for the spatial transformations and correspondingly there is a challenge to conserve & preserve the religious precincts of historic towns. The study tries to analyze spatial transformations with the help of Historical GIS at different scales of urban form. Suggestive measures to conserve the environmental ambience of religious-historic towns are the outcome of the research.

根据Bandura的社会认知论,消费者、新技术和采用三者之间是一个辩证的三方互惠决定体系。通过对几种基本的用户接受度模型(TAM、TPB、VAM)进行综述和分析,本文采用三方互惠决定论的理论框架,结合价值理论和自我效能感的概念提出一个新的用户接受度模型——基于自我效能感的价值接受度模型(SVAM)。针对新兴的移动互联网业务,本文采用结构方程模型(SEM)对移动拍卖的用户接受进行了实证研究。结果表明,基于自我效能感的价值接受度模型SVAM可以更好地解释用户的采用意图。在自愿购买的消费市场中,用户的自我效能感影响了用户对产品或服务的感知价值,并直接影响消费者的态度和采用意图。尤其当消费者缺乏基本的使用经验时,自我效能感将具有更显著的影响作用。

对目前网络拍卖进行研究发现,在线多属性采购拍卖的实施水平仍处在基础的信息发布阶段。基于委托代理模型的参与约束和激励相容约束,通过改进多属性决策的一般方法,提出一种以释放权重信息为核心的在线多属性采购拍卖设计机制。拍卖设计的第一阶段融入谈判机制以协商拍卖的属性规则,确定多维拍卖的属性选择;第二阶段通过投标人提供的属性赋值和权重设置确定赢者的胜出。为开发实际的在线网络采购或供应链管理平台,进一步提出基于多Agent系统的多属性采购拍卖的技术实现框架。通过一个简单的二维属性拍卖的例证分析,说明该机制可以增进拍卖双方信息的正向交互,实现拍卖机制的最优,并可以通过多Agent系统提高在线拍卖的效率。

Journal of Transportation Technologies 2019年第1期9卷 56-77页

Suitable speed limit is important for providing safety for road users. Lower-than-required posted speed limits could cause the majority of drivers non-compliant and higher-than-required posted speed limits may also increase the number of crashes with related severities. The speed limit raised in Kansas from 70 mph to 75 mph on a number of freeway segments in 2011. The goal of this study is to assess the safety impacts of the freeway sections influenced by speed limit increase. Three years before and three years after speed limit increase was considered and three methods were used: 1-Empirical Bayes (EB), 2-before-and-after with comparison group, and 3-cross-sectional study. The Crash Modification Factors (CMFs) were estimated and showed 16 percent increase for total crashes according to EB method. Further, the before-and-after with comparison group method showed 27 percent increase in total crashes and 35 percent increase on fatal and injury crashes. The cross- sectional method also presented 25 percent increase on total crashes and 62 percent increase on fatal and injury crashes. It was seen that these increases were statistically significant.
