Based on conflicting-point method, the internal mechanism of left-turn flow after stopping line was analyzed through taking postposition left-turn lane waiting-zone intersection for instance. The relationship between the first left-turn vehicle and the last vehicle of previous phase passing the conflicting point was expounded. According to the time of successive arriving of two vehicle flows at conflicting-point, the reasonable layout for waiting area of left-turn vehicles was researched when the clearance index was less than O. The results suggest that the appropriate layout for waiting area of left-turning vehicles can improve the operation efficiency of intersections.展开更多

This route conversion will not only have an impact on the maritime business activity in the Suez Canal, but also the Egyptian economy in several aspects when the number of vessels passing through the Suez Canal and the Indian Ocean decreases. The aim of this study is to analyze the impact of the opening of the Northern Sea route on maritime sector of the Egyptian economy. The scope of this study is concentrating on the Suez Canal shipping activity by using the statistics that have been received from Suez Canal Authority through a set of direct and indirect interview sessions with authority＇s experts.展开更多
