This article presents a generalized diversion control model for freeway incident management that is capable of concurrently optimizing the detour rates and arterial signal timings over multiple roadway corridor segments between the freeway and its neighboring arte-rial. To capture various operational complexities due to the interactions between mul...

The main motivation of this paper is to analyze the influences of speed guidance strategies on the driving behaviors under four different traffic signalized conditions and to investigate an extended car-following model to explore how the speed guidance affects two different vehicle types that are intelligent vehicles and traditional vehicles during...

Lane reorganization strategies such as lane reversal, one-way street, turning restriction, and cross elimination have demonstrated their effectiveness in enhancing transportation network capacity. However, how to select the most appropriate combination of those strategies in a network remains challenging to transportation professionals considering...

In this paper, we propose a car-following model to explore the influences of V2V communication on the driving behavior at un-signalized intersections with two crossing streams and to explore how the speed guidance strategy affects the operation efficiency. The numerical results illustrate that the benefits of the guidance strategy could be enhanced...

As the world is getting wealthier than ever, how come we also witness more shortages? How should a socially growth-minded government go about with its surplus redistributive strategies? Should the good-old resource conservation laws be simply abolished? We built an analytical model to inform and expand these political dialogues. Find out what we ha...

The unbalanced nature of passenger demand and the uncertainty of delay at intersections are considered critical factors in the efficiency of public transportation operations. Considering the controllable characteristics of the bus rapid transit system (BRT), an integrated optimization model that includes multi-mode transit scheduling and signal tim...

In the era of a growing population, systemic changes to the world, and the rising risk of crises, humanity has been facing an unprecedented challenge of resource scarcity. Confronting and addressing the issues concerning the scarce resource's conservation, competition, and stimulation by grappling its characteristics and adopting viable policy inst...

Many companies nowadays offer compensation to online reviews (called compensated reviews), expecting to increase the volume of their non-compensated reviews and overall rating. Does this strategy work? On what subjects or topics does this strategy work the best? These questions have still not been answered in the literature but draw substantial int...

In urban expressways, when an on-ramp and off-ramp pair are closely spaced, the operational condition of the downstream diverge area influences that of the adjacent upstream merge area because of the weaving movement and queuing. Although lane-changing management schemes have often been used in practice, the quantification effect of specific manage...

The vehicle-pedestrian encounter at midblock crosswalks in urban centers is inevitable but the challenge to urban transportation planners is in achieving a balance between traffic flow efficiency and pedestrian safety. Vehicles are expected to yield to pedestrians who have a right of way at the midblock unsignalized crosswalks but, failure to yield...

The traffic weaving area is one of the key bottlenecks affecting the operation efficiency of an urban expressway system. The main motivation of this study is to explore the effects of lane allocation on the operational efficiency at weaving areas. A cellular automaton model was established, in which three different lane-changing rules were consider...

Pedestrian illegal crossings at midblock are very unpredictable and pose a potential tragic conflict with vehicles besides generally disrupting the normal flow of traffic. The drivers need to not only anticipate but also respond to their actions accordingly to avoid potential conflicts. The objective of this paper was to describe the behavior of th...

An extended car-following model is proposed in this paper to analyze the impacts of V2V (vehicle to vehicle) communication on the micro driving behavior at the un-signalized intersection. A four-leg un-signalized intersection with twelve streams (left-turn, through movement, and right turn from each leg) is used. The effect of the guidance strategy...

A tandem intersection is an unconventional intersection design that possesses the important property of increasing the traffic capacity using pre-signals and sorting areas. However, the operational efficiency of the lanes in the sorting areas may be affected by driver unfamiliarity and confusion. This study evaluates the effect of the tandem contro...

Highway Capacity Manual 2010 provides various factors to adjust the base saturation flow rate for the capacity analysis of signalized intersections. No factors, however, is considered for the potential change of signalized intersections capacity caused by the access point closeing to the signalized intersection. This paper presented a theoretical m...

Lane group capacity under the impact of access traffic flows. (DOCX)

Midblock crosswalks are installed mainly at locations with heavy pedestrian traffic to increase the accessibility of points along the streets to pedestrians. However, midblock crosswalks may cause additional delays for vehicles. This paper presents an integrated design method for midblock crosswalks that balances the trade-off between the efficienc...

An ecodriving speed control algorithm is proposed for a platoon of vehicles at a signalized intersection. Both the running status of the target platoon and the impact of the downstream platoon are considered and analyzed. The acceleration-deceleration profile, instead of speed trajectories, is used in this research as the optimization objective to...

Considered the conflicts of pedestrian, non-motor vehicle and right turning vehicle in the crossing as factors of design, the types and quantities of crossing was summarized and the defects was explained. Taken the minimization of conflicts as the design goal, based on the method of conventional four-phase signal control , a new signal control meth...

In this paper, we develop a macro model for traffic flow with consideration of static bottleneck to explore the impacts of static bottleneck on traffic flow. The analytical and numerical results show that the proposed model can qualitatively describe the equilibrium flux, uniform flow and small perturbation under the action of a static bottleneck.
