This paper proposed a new method to describe, compare, and classify the traffic congestion points in Beijing, China, by using online map data further revealed relationship between land use. The of point interest (POI) real-time was extracted from an electronic area fourth ring road Beijing. POIs were quantified based on architectural use; identified traffic. Then, cluster analysis attributes time conducted identify main areas. result linear regression use showed that influence high...

This paper focuses on land use as the primary variable for transit ridership estimation, with 100 000 points of interest (POIs) in Beijing being extracted from a digital map and classified into five categories according to main trip purposes. To better quantify characteristics surrounding station further assist sustainable zoning, multi-level catchment area delineation method that includes pedestrian, traffic, potential areas is applied. The built different POIs within various are used...

Human-driven vehicles (HDVs) will share the road with connected autonomous (CAVs) in near future. Accordingly, investigation of interactive behavior HDV drivers toward CAVs is becoming critical. In this study, a questionnaire survey was first conducted. The heterogenous clusters were revealed through latent profile analysis based on collected dataset, focus their trust and familiarity CAVs, attitudes towards sharing risk perception perceived control when they faced CAVs. Subsequently,...

The importance of a transportation terminal's transfer efficiency to passengers is well known. However, it still problem how combine the various indicators into single indicator that can be used quickly compare terminals' and identify those terminals in need intervention. This paper presents study reflective such an effort. Using data obtained from 10 Beijing, individual performance measures were combined comprehensive measure through envelopment analysis (DEA). Efficiency allowed measured...

Weaving area may be the critical risk place in subway transfer station. When improving service level of weaving area, characteristic pedestrian behavior should systemically discussed. This paper described mechanism on high density which was analyzed by collection data controlled experiment. Different behaviors were contrasted due to different volumes bidirectional passageway. Video analysis conducted extract moving and calibrate movement with SIMI Motion. Influence studied based statistical...

Summary Sustainable land use planning and advanced public transport system are believed to be effective solutions traffic congestion. To this end, it is important reveal the relationship between transit ridership use. However, current Direct Ridership Models only focus on single station's boarding volume corresponding catchment area This paper analyzed distribution stations by considering difference areas. Land was calculated from point of interest (POI) data extracted an electronic map...

The traffic signs transfer trip information to drivers through vectors like words, graphs and numbers. Traffic sign with excessive often makes the have no time read understand, leading risky driving. It is still a problem of how clarify relationship between recognition driving behavior. This paper presents study that reflective such an effort. Twenty volunteers participated in dynamic visual experiment simulator, data several key indicators are obtained, including cognition time, vehicle...

Since the quantitative methodology analysis of high-density pedestrian shockwaves at a bottleneck is limited, this paper proposes dynamic time warping (DTW) algorithm for identifying, analyzing, and verifying shockwaves. A set real-world trajectory data used to illustrate proposed algorithm. Results show that DTW capable depicting elaborately accurately. also shockwave velocity unsteady, as throughout gathering wave evanescent are decreasing increasing, respectively. The mutual influence...

Service capability and matching degree of transfer facilities are directly related to the operational efficiency safety a subway station. Owing differences in planning construction, stations developing countries have some defects facility size serviceability, which cause decline service performance, operation efficiency, security level. In order solve problems, traffic investigations were conducted on form, size, status several typical facilities. The classified within station this research...

Due to the poor transfer organization in urban public transport terminal, pedestrian crowd are often forced weaving their flow lines. Frequent behaviors not only decrease passengers’ comfort, but may also trigger serious disaster such as trampling. In order get accurate understanding of features and analyze relevant evolution law, researches have been conducted on basis field investigation. First, typical phenomenon were defined classified, a microscopic parameters system was constructed....

The mixed traffic of conventional vehicles (CVs) and connected autonomous (CAVs) will dominate a long period in the popularization CAVs its dynamics are still not clear, especially some complicated scenarios. In this paper, an improved cellular automaton model was applied to investigate CVs–CAVs around freeway merging area. lane-changing rules were consider difference between CVs also variation drivers’ aggressive driving during process. simulation has been conducted with different demands...

In subway stations, bottlenecks are the narrowed areas that reduce pedestrian flows in channels. Because pedestrians at forced to dense together, decrease flow efficiency and pedestrians’ transfer comfort may trigger serious crowd disasters such as trampling. This study used experiments investigate methods of optimizing traffic stations. Three optimization measures were proposed evaluated by analyzing characteristics flows, including efficiency, smoothness, security. this paper, setting rear...

Transportation terminal is the key node in transport systems. Efficient terminals can improve operation of passenger transportation networks, adjust layout public provide a guidance system, and regulate development commercial forms, as well optimize assembly distribution modern logistic modes, among others. This study aims to clarify relationship between function structure establish design. The mapping mechanism demand, function, was analyzed, quantitative obtained from design perspective....

Intersecting streams of pedestrians are frequently seen in subway stations. When two or more such encounter each other the normal way, there is interference progress and a reduction speed. This research explores impact roundabout design on intersecting pedestrian by conducting series experiments field. First, size different volumes traffic examined; second, effect adding guiding signs investigated; third, case where greater number intersect studied. Results indicate that, although placing at...
