Imagine in the future that autonomous vehicles coordinated and guided by signal-free intersections are able to pass through immediately after conflicting direction leave. Meanwhile, with coordination of intersections, on any approaching lane turn onto downstream lane, expecting driving such a road system, can reach their destinations without on-road changes, high traffic efficiency will be achieved as well great safety. To draw picture detail, this paper designs intersection all-direction...

In the upcoming decades, connected vehicles will join regular on road, and characteristics of traffic flows change accordingly. To better understand mixed flow (regular vehicles) characteristics, a generic car-following modeling framework for this new an urban road under vehicle environment is proposed in paper. Considering vehicle's speed, which affected by speed preceding vehicle, improved intelligent driver model (IDM) used as vehicles. An extended cooperative adaptive cruise control...

A spatiotemporal speed contour (SSC, or time-space traffic) diagram that exhibits traffic dynamics in time and space is of importance transportation research applications. This paper empirically investigates the feasibility using non-rectangular parallelogram (nRP) cells to construct SSC diagram, given complete trajectory probe vehicle data. Compared with traditional way rectangular (RP) cells, nRP further considers direction backward-moving wave. The dataset provided by Next Generation...

Walking in groups is very common a realistic walking environment. An extended floor field cellular automaton (CA) model therefore proposed to describe the behavior of pedestrian groups. This represents motion way. The simulation results reveal that has an important but negative influence on flow dynamics, especially when density at high level. presence retards emergence lane formation and increases instability operation flow. Moreover, average velocity volume are significantly reduced due...

Loop detectors distributed on freeways are very vulnerable and could be damaged or malfunctioned due to improper sealing, pavement deterioration. This may lead poor travel time estimation as most of existing methodologies require detailed data collected from numerous along a specified freeway route. To address this problem, study proposes an effective reliable methodology for real‐time with sparse detectors. In contrast the methods, proposed requires significantly less number but maintains...

Once unplanned urban rail disruptions occur, it is essential to evaluate the impacts on public transport passengers since impact estimation results enable transit agencies verify whether alternative services have adequate capacity evacuate affected and adopt effective emergency measures in response disruptions. This paper focuses estimating of line segment as well original bus passengers, latter are overlooked existing studies. A method identifying based passenger tap-in time proposed, which...

Shared parking is not commonly applied in residential areas. The reason that suppliers and managers believe there are many uncertainties conflicts obtaining sharing benefits taking risks. To increase their acceptance of shared areas, risk benefit factors were identified by an influential analysis a questionnaire survey. A research framework based on the structural equation model was developed to analyze relationship between shared-parking risks, benefits, management pressure, intentions...

With the concept of sharing economic entering into our lives, many parking Apps are designed for connecting drivers and vacated spaces. However, there not who use mobile to reserve find available spaces, which is largely due insufficient information provided by App. In order better explain, predict, improve drivers’ acceptance App, conceptual framework based on technology model was developed establish relationships between intention accept trust in perceived usefulness ease its use. Then...

This paper proposes a novel model to optimize the first train timetables for urban rail transit networks, with goal of maximizing passengers’ transfer waiting time satisfaction. To build up relationship and passenger satisfaction, reference-based piecewise function is formulated consideration expectations, tolerances dissatisfaction on “just miss”. In order determine parameters zero satisfaction rating, most comfortable time, maximum tolerable in function, stated preference survey conducted...

This paper focuses on the bus bridging service design in response to an unplanned metro line segment disruption. An integrated optimization model is constructed address both route layouts and resource allocation. Diversified routes, e.g., stop-by-stop route, express skip-stop parallel disrupted are applied optimized scheme best respond passenger demands. event-driven simulation-based genetic algorithm designed solve model. The simulation method introduced handle uncertainty of waiting time...

In this paper the experiment to study features of pedestrians' walking preference is designed. Then cellular automata model which considering built, in forward-parameter, right-parameter, surpass-parameter and correction-parameters are included mend probability pedestrian getting each neighboring cell. Based on k-nearest-neighbor interaction pattern, complex network pedestrians modeled. The simulation results obtained from well illustrate density-speed curve density-volume curve. Meanwhile...

Travel time distribution estimation is fundamentally important for the evaluation of travel variability and reliability. For urban roads, signal delays are key components time. They stochastic differ vehicular movements due to different timings through, left-turning, right-turning vehicles. To better assist travelers in making trip decisions under connected environments, this study seeks investigate lane-level distributions signalized arterial roads by specifically considering impacts both...

Three types of different walking behaviors (right preference, conformity, and space priority) are taken into account to model bi-directional pedestrian flow in the channel with cellular-automata formulation.

Non-coordinated first-train timetables can result in unfavorable train connections among different subway lines at transfer stations and generate rather long waiting time for passengers. This paper aims optimizing the first originating times of transit network scale. The cost function is formulated to evaluate perceived quality with consideration passengers' psychological feelings. timetable coordination model then developed by minimizing total passengers transferring between two trains...
