Model and Simulation of the Heterogeneous Traffic Flow of the Urban Signalized Intersection With an Island Work Zone

Modeling the Traffic Flow of the Urban Signalized Intersection with a Straddling Work Zone

“…However, their model was a statistical model, and the mechanism of how work zones impact the intersection traffic flow was still unknown. Recently, Yang et al [7] focused on a specific type of work zone which is located within the area of the intersection, namely, the island work zone, and proposed a novel model for the traffic flow of the island work zone based on the social force theory. ey evaluated the proposed model by field work zone data, while the results indicated that the model obtained high performance.…”

“…Work zones exist widely on both freeways and city arterials in many countries and have a significant negative impact on the road traffic. According to the existing studies, work zones will cause heavy traffic congestion and more traffic accidents [1][2][3][4][5][6][7]. It is necessary to look for the ways of reducing the influence of work zones on traffic.…”

“…e straddling work zone refers to the work zone that straddles both an intersection and a road segment (see Figure 1(b)). Yang et al [7] had proposed a traffic flow model for the island work zone and analyzed the traffic flow characteristics. However, the traffic flow model for the straddling work zone has not been proposed yet.…”

“…Meanwhile, in the straddling work zone, the traffic flow has strong interaction with the oncoming traffic flow. us, the proposed traffic flow model for the island work zone by the authors in [7] cannot be applied to the traffic flow of the straddling work zone, and the new model is necessary. In our research, the social force theory is applied to model the traffic flow of the straddling work zone, and we construct a non-lane-based model to overcome the shortcomings of the conventional microscopic traffic flow models, which describes the traffic flow of the straddling work zone.…”

“…The transport performance of road freight transport is significantly growing [15][16][17], while the importance of transport modes suitable for the transport of large volumes of goods without excessive burden on infrastructure and the environment declines, or it is completely negligible in the total transport volume [18,19]. Many studies [20][21][22][23][24] have focused on traffic modeling using simulation, which is a cost-effective solution. Simulation is used for answering the question "what if?"…”
