China is currently in a rapid urbanization phase, and road traffic accidents occur frequently, with vulnerable users often being easily injured. Traditional safety research focuses on environmental structural issues or considers human factors as the cause of accidents. This study organized 30 to travel quadrangular area Wudaokou Beijing, collected language data from subjects for analysis, attem...

This article proposes an energy management system (EMS) for shared electric bicycles. The objective is to guarantee assistance the cyclist while avoiding discharging battery. basic working principle exploits cycling efficiency gaps. proposed multilayered EMS specifically tailored a free-floating bike-sharing setting. innermost layer manages and harvesting with of yielding intuitive human–machin...

With the development of sharing economy and advocacy green travel, shared bicycles came into being are rapidly popularized in major cities. Due to large number mountains Chongqing, popularity bike is not very high. However, as a frontier municipality with numerous colleges universities, its future market considerable. will also bring many problems, especially vehicle management. If handled prop...

This paper presents systematic analysis and design of power split-hybrid configurations using a single planetary gearset and two electric machines for human-powered vehicles. All the 12 possible power split hybrid configurations are investigated, and their performances are compared to a normal (no power assist) bicycle, and two electric bicycles. Several performance indices, including the cycli...

Shared e-scooter programs often generate complaints about improper parking because it create unappealing clutter and can make difficult for pedestrians to use the sidewalk. We examine how cities address noncompliant scooter explore public perceptions of this problem with two related studies. First, we conducted field experiments in Washington, DC (hereafter "DC"), Auckland, New Zealand...

The pedaling a conventional bicycle nowadays turns crank to rotate the front gear, which transmitted rear gear by chain, axle wheel. Since require human power pedal, structur...

The 'greening' of transport is an ongoing concern in today's cities, with many struggling to reach carbon emission targets. One relevant area for effecting change is encouragement and facilitation of alternative, non-motorised transport modes, such as cycling and walking. Understanding the dynamics of non-motorised flows and their interaction with motorised traffic in an urban context is fundam...
