Based on investigation and literature collation,the evaluation factors of regional characteristic landscape along the commercial pedestrian street were extracted,and the evaluation system of regional characteristic landscape along the commercial pedestrian street was established by the AHP method.The regional characteristic landscape along the commercial pedestrian street is the first-level index,including four secondary indexes of regional characteristics of road landscape,regional characteristics of plant landscape,regional characteristics of architecture and sketch,and spatial landscape experience,as well as 17 three-level indicators such as road environment landscape coordination,uniqueness of road markers and road landscape recognizability.The reliability of the evaluation system of the regional characteristic landscape along the commercial pedestrian street in Dongpo Bund was proved.The importance sequence of road landscape level,spatial landscape experience,landscape visual effect and plant landscape characteristics in the regional characteristic landscape was obtained,and it is closely related to users’ satisfaction.According to the problems found in the survey,suggestions on the transformation of the regional characteristic landscape along the commercial pedestrian street in Dongpo Bund were put forward to provide reference for the transformation and improvement of regional characteristic landscape along similar urban commercial pedestrian streets.

Spatial Quality Evaluation of Pedestrian Streets

This paper presents an assessment of the spatial quality of a pedestrian street located in downtown Bauru, S^o Paulo State, Brazil, from the application of some urban sustainability indicators. Multi-method was used to evaluate the thermal comfort quality of users, urban accessibility and preservation of architectural heritage. The results show that the sustainability indicators, apart from being effective tools in identifying problems, can assist local managers in decision making, planning and monitoring of pedestrian public space. These indicators contribute to a broad diagnosis of the pedestrian street and also the formulation of programs, projects and municipal policies, aimed at providing a better life quality for pedestrians.

Reviving the Historic Street through Pedestriansation: In the Case of Haileselassie Street, Piazza, Addis Ababa

Pedestrianisation is seen as a necessity in many cities of the world.Streets are main representatives of the city image,which have its reflection of its home country.Haileselassie Street in Piazza is shaped after the short-term confrontations of the Italians that profoundly affected the entire downtown.The prideful victory of Ethiopia is an important landmark of the urban fabric in Piazza,Addis Ababa.The Haileselassie Street lacks its vista and approach it deserves.Therefore,this paper introduces the scheme of pedestrianisation in Haileselassie Street by reclaiming the street for the people in order to remember the history.The pertinent questions this article seeks to address are:the factors that aim to transform the street into a‘pedestrian’street only?Which aspects of the pedestrianisation should be considered to improve the quality of the Haileselassie Street?Moreover,this article recommends the strategic proposal to improve the quality of the pedestrians in urban space.

道路信号交叉口行人过街速度与延误估计仿真

为了探究信号交叉口行人群体过街速度和延误影响因素,采用无人机和地面机位从高空和地面获取交通视频,并利用Tracker物理影像分析软件对视频数据进行分析。从城市信号交叉口的微观角度出发,建立了传统社会力模型和改进社会力模型,通过仿真场景模拟了行人过街情况。利用哈尔滨市两个交叉路口的实际参数对仿真模型进行了标定。实验结果显示,当人行横道宽度从4 m增加至7 m过程中,传统社会力模型下的行人过街平均延误时间分别为4.22 s、3.47 s、2.57 s和2.28 s;改进社会力模型下的行人过街平均延误时间分别为3.56 s、2.91 s、2.78 s和2.26 s。经过对比验证发现,适当提升人行横道宽度使行人实际过街速度更接近期望速度,从而降低行人过街的延误时间。结果表明,通过增加人行横道宽度可以有效改善信号交叉口行人过街的效率。

公路无信号交叉口行人过街主动安全预警技术研究应用

农村公路的本质决定了其接入干线公路存在“点多、面广、分布散”的特征。而现状交叉口普遍存在视认性差、视距不足、缺乏接入管理和交通管制、安全设施不完善、交通参与者安全意识相对薄弱、交通行为的盲目性和随意性大等问题,给道路交通安全埋下了安全隐患,一直是农村公路交通安全管理中的痛点和难点。近年来,针对农村公路交叉口警示的建设越来越多,管理的投入也越来越大,但很多都是常规的静态警示功能。传统静态防范手段无法感知判断道路交通参与者的运行信息,仅通过静态信息放大的方式往往会给驾驶员带来信息疲劳,无法达到及时提醒的目的。文章通过利用智能感知、计算机等技术,研究开发公路无信号交叉口行人过街主动安全预警技术,对交叉口的人、车进行主动探测、提前预警,提高交叉口的交通安全。
