Bài viết Nghiên cứu quy luật thời gian xe đến thực tế với dòng giao thông hỗn hợp trên một số tuyến đường đô thị ở Hà Nội trình bày nghiên cứu về quy luật xe đến, cụ thể là thời gian xe đến thực tế trên một số tuyến đường đô thị ở Hà Nội. Nghiên cứu đã đề xuất một phương pháp xác định thời gian xe đến thực tế cho dòng xe hỗn hợp chạy không theo làn với dòng giao thông ở Việt Nam. | Transport and Communications Science Journal Vol 72 Issue 5 06 2021 580-590 Transport and Communications Science Journal A STUDY ON ACTUAL ARRIVAL PATTERN OF VEHICLES ON URBAN STREETS IN HA NOI WITH MIXED TRAFFIC FLOW Dang Minh Tan Tran Danh Hoi University of Transport and Communications No 3 Cau Giay Street Hanoi Vietnam ARTICLE INFO TYPE Research Article Received 31 12 2020 Revised 19 05 2021 Accepted 25 05 2021 Published online 15 06 2021 https Corresponding author Email tandang@ Tel 0983996556 Abstract. Since the arrival pattern is an important parameter to describe traffic flow. It directly affects the quality of the traffic flow such as delay length of queue on the road traffic network. The rules of traffic arrival pattern can be used to solve the problem of traffic operation and safety for road facilities such as intersections tolls or merging diverging segments in expressways. The paper presents a study on the actual arrival pattern particularly the study on actual time headway of vehicles on several urban streets in Ha Noi Viet Nam. The study proposed a method for determining the actual time headway with non-lane based concept in mixed traffic conditions in Vietnam. On that basis a field survey was conducted to collect data including geometrical factors and traffic data such as volume vehicle composition actual time headway on three road segments in several urban streets in Hanoi. Initially the study focused on analyzing the traffic flow at off-peak hours. Each road segment 1-hour period was chosen for analysis. The analysis results of headway based on the proposed arrival pattern determination method shows that the arrival headway of the mixed vehicle follows the three-parameter Log-normal distribution and depends on the traffic volume. Keywords actual arrival pattern actual time headway traffic congestion driver behavior mixed traffic. 2021 University of Transport and Communications 580 Tạp chí Khoa học Giao thông
