Opis:
In this study an attempt is made to investigate the characteristics of road traffic accidents on the Rajshahi-Sirajganj Highway in Bangladesh. For detail investigation, the highway was divided into three major sections as Section-I: Bonpara intersection to Parkol, Section-II: Parkol to Nayabazar and Section-III: Nayabazar to Toll Plaza. Road accident related data on selected highway for different years were collected from Bonpara Highway police station, Jholmoliya Highway Police Station and Fire Service and Civil Defense Station at Natore from year 2008 to 2015. From the investigation, it is found that the total numbers of accidents in Rajshahi - Sirajganj highway (Bonpara intersection to Atrai toll plaza) were 210 within year 2008 to year 2015; the number of fatalities, grievous injury and minor injury were 246, 231 & 265 respectively. It is also found that the maximum numbers of accidents (22%) occurred within 12 AM to 15 PM. Truck was the most involved vehicle in the road accident which is 39% of the total number of vehicles whereas, bus involved is 21% road accidents. From the year 2014 to 2015 there were 30% head on collisions, 34% rear end collisions, 29% hit pedestrians and 7% overturning occurred. A 3D model of Bonpara-Hatikumrul highway is proposed in this study, where the selected highway is developed into four lanes and the movements of fast moving vehicles are kept uninterrupted by providing a grade separated intersection.

Opis:
For centuries, it is known that people always prefer to accommodate in the region where there is good transportation network. Proper organization of transportation is one of the key elements which influence the dynamics of the World economics system development. Thanks to infrastructure modernization which allows to transfer the goods between engaged parties, it is possible to increase production and commonly to intense exploitation of areas located near this infrastructure among others in industry purposes. With regard to increasing demand for effective and efficient transportation system, there is a real need to improve communication and transportation infrastructure. A chance for this target shall be modern high technologies, which allows running with very high speed and thus also to reduce journey time. For this purpose there were established and is still developing relatively new product – high speed rail which is supposed to revolutionize modern transportation system functioning in the World. The article calls attention on a chance for improving competitiveness of rail freight transportation in Poland thanks to developing high speed rail network. There is underlined also rationality of modernization of the rail line which connect the biggest cities in South part of Poland. The descriptive part of the article refers to the high speed rail system and its development conditions. The research part is a technical feasibility study about section Cracow – Katowice – Wroclaw and possibilities for adopting it to achieve high speed rail line parameters.
