Abstract: One of the major problems related to road injuries and deaths are the presence of Black Spots. This problem has received a growing amount of attention from road managers thorough last decades, taking into account its importance for the safety of road users. In fact, knowledge about these strategic areas among drivers seems to be quite important, since this conceptualization may affect their behavior and assumed risks on the road. The main objective of this research was to assess the knowledge that drivers have on the concept of black spot and other closely related terms: “grey spot” and “high accident concentration sections”. For this study, it was used a random sample of 200 drivers from the province of Valencia (Spain), between 18 and 64 years of age. Through data analysis it was found that, while most of drivers does know the concept of black spot properly (87.5% of them), this trend is not stable when knowledge of related concepts is assessed. In regard to the further technical terms addressed by this study (grey spot and high accident concentration sections), there is an elevated relative percentage of drivers who have very biased misconceptions about these concepts. With respect to the "grey spots", in which knowledge barely reached 13% of the driving population, unfamiliarity rate increased significantly. As conclusion, in regard to the concept of “high accident concentration sections”, it was found that it is a really misunderstood, relativized and biased concept among population of drivers and, furthermore, in general, unknown to most of road users. Finally, it has been suggested that the public administrations should work to increase this knowledge, as it would allow drivers to adopt more cautious behavior when confronted with this potentially dangerous sections throughout their routes.

Abstract: Traffic surveys are means of obtaining information about the traffic characteristics of an area. The data collected is used for traffic assessment of the area for various Engineering purposes. This study was an attempt to conduct a traffic assessment for the purpose of pavement design. Three design methods: Road Note 29 (RN 29), Laboratory Report 1132 (LR 1132), and Design manual for Highways and Bridges (DMHB; HD 26/01), were adopted. Three locations along the Onitsha-Enugu expressway, a Nigerian interstate highway, were surveyed. The highest volume of commercial vehicles was observed at the Nkpor location with corresponding design traffics of 108msa, 304msa, and 92.92msa using RN 29, LR 1132, and HD 26/01 respectively. Computed design traffics for Nkpor, Awkuzu, and Kwata locations using LR 1132 were 304msa, 175msa, and 167msa respectively. These were found to be significantly higher than those computed using RN 29 and HD 26/01 due to the fact that a uniform damaging factor was computed for the entire traffic count without any form of categorization or weight impact discrimination. It was concluded that the traffic assessment method to be adopted for any pavement design purpose should be consistent with the design method to be used for the selection of pavement thicknesses.

Abstract: The urban train system is known as an energy-efficient and environmentally-efficient public transportation system. In this study, we suggest the method of constructing spatially the most realistic CO2 emission inventory by using a bottom-up approach with actual traffic amounts of urban train. We also developed the energy efficiency and the environmental efficiency of urban trains and we compared them with the other transport system in Seoul. As a result, the urban train system was shown as highly energy-efficient and environmentally-efficient public transportation system. The energy efficiency of the urban trains of Seoul were calculated as 58 ~ 111 kcal/p∙km, which was about one-tenth of the level of sedans and one-fourth the level of busses. The environmental efficiency was calculated 12 ~ 22 gCO2/p∙km, which was about one-eighteenth the level of sedans and one-fifth the level of busses.

Abstract: Issues and problems of organization and management of urban passenger transport systems have always been the main research subject for many scientists. Managing the transportation of passengers is particularly connected with the issues of tariff setting for urban passenger transport routes, improving distribution circuits of transport and related financial flows, determining fare exposure patterns on the performance measure of urban passenger transport systems. Raised and resolved tasks in the scientific work are essential for resolution to the issues related to the organization and management of urban passenger transport systems. The approaches are of particular interest in practical and theoretical parts in the organization and management of urban passenger management systems through fares mechanisms and distribution of transport work.
