Situation and hotspot analysis on rural transport infrastructure from the perspective of bibliometric analysis

The construction of rural transportation infrastructure is of great significance to promote the organic integration of transportation construction with resource exploitation and industrial development in rural areas,and realize poverty alleviation and poverty reduction driven by convenient transportation.In order to understand the research status of rural transport infrastructure at home and abroad,this paper adopts CiteSpace,VOSviewer,Pajek,SPSS and other software and makes quantitative analysis and knowledge map drawing of the literature on rural transportation infrastructure collected in Web of Science database.The results show that the emphasis of this field is different in different periods,Chinese scholars'attention to this field increased significantly after the rural revitalization strategy was put forward.Based on the classification results of keyword clustering,the following conclusions are drawn:The planning mode of rural transportation infrastructure under rural revitalization is relatively backward and the lack of theoretical analysis of the root causes has achieved the purpose of rational allocation of transportation resources.Moreover,there are few studies on the mechanism and empirical analysis of transport infrastructure's effect on rural poverty reduction.From the analysis of research hotspots,the integration of urban and rural areas and rural road safety will be the main research direction in the future,and rural road accidents and other topics have research potential.

Factors associated with crash severities in built-up areas along rural highways of Nevada:A case study of 11 towns

In 2014, 32,675 deaths were recorded in vehicle crashes within the United States. Out of these, 51% of the fatalities occurred in rural highways compared to 49% in urban highways. No specific crash data are available for the built-up areas along rural highways. Due to high fatalities in rural highways, it is important to identify the factors that cause the vehicle crashes. The main objective of this study is to determine the factors associated with se- verities of crashes that occurred in built-up areas along the rural highways of Nevada. Those factors could aid in making informed decisions while setting up speed zones in these built-up areas. Using descriptive statistics and binary logistic regression model, 337 crashes that occurred in 11 towns along the rural highways from 2002 to 2010 were analyzed. The results showed that more crashes occurred during favorable driving conditions, e.g., 87% crashes on dry roads and 70% crashes in clear weather. The binary logistic regression model showed that crashes occurred from midnight until 4 a.m. were 58.3% likely to be injury crashes rather than property damage only crashes, when other factors were kept at their mean values. Crashes on weekdays were three times more likely to be injury crashes than that occurred on weekends. When other factors were kept at their mean value, crashes involving motorcycles had an 80.2% probability of being injury crashes. Speeding was found to be 17 times more responsible for injury crashes than mechanical defects of the vehicle. As a result of this study, the Nevada Department of Transportation now can take various steps to improve public safety, including steps to reduce speeding and encourage the use of helmets for motorcycle riders.

Rural Transporter in China

Rural transporter is a specialized short-distance vehicle newly developed in our country for rural areas. Put into market at the beginning of 1980, its production of 1984 went to 28000 units. The last decade has witnessed its highspeed increase. In 1994, its production and sales volume got to 1.6 million units (The auto output that year was 1.38 million units), and in 1995 it hiked to over 2.5 million units.
