“…Not all intersections are standard, which can be the results of urban scheming, building near the intersection, imbalance between the number of lanes, road markings, and traffic optimization [4][5][6]. Cross intersections [7] and T-intersections [8] are commonly used shapes, whereas roundabouts [9,10] and unconventional intersections [11] are not rarely seen. All these forms of intersections affect traffic operations to different degrees [12].…”

The impact of work zones on traffic is a common problem encountered in traffic management. The reconstruction of roads is inevitable, and it is necessary and urgent to reduce the impact of the work zone on the operation of traffic. There are many existing research results on the influence of highway work zones, including management strategies, traffic flow control strategies, and various corresponding model theories. There are also many research results on the impacts of urban road and subway construction on traffic operation, including construction efficiency, economic impact, and travel matrix. However, there are few studies concerning the choice of work zone location, and most previous studies have assumed that the work zone choice was scientific and reasonable. Therefore, it is reasonable to choose the location of the work zone and to assess whether there is room for improvement in the road form of the work zone, but this remains a research gap. Therefore, we studied a seven-lane main road T-intersection in Xi’an, China, and investigated a work zone located at this intersection that caused a road offset, leading to the non-aligned flow of main traffic. We designed two road improvement schemes and multiple transition schemes, used VISSIM software to evaluate the traffic operation of the two schemes, and used the entropy method to choose the suitability of the two schemes under different conditions. According to the results, in the best case, the driving time, delay, and number of stops are reduced by 44%, 66%, and 92%.

“…Kerner and Klenov [14] established a two-lane model considering driver characteristics and vehicle parameters. The CA model plays an important role in traffic research, including research on traffic intersections and ramps [15][16][17][18][19][20][21]. Ruskin and Wang [22,23] studied the motion characteristics of vehicles at intersections without signal control, and the concept of the acceptable headway of a vehicle was proposed.…”

“…In the field of trac flow, phase diagrams of trac states induced by various bottlenecks (e.g. o-ramps, on-ramps, roundabouts, and unsignalized and signalized intersections) have also been studied [29][30][31][32][33][34][35][36]. In order to facilitate analytical investigations, researchers usually start from a simple intersection (crossroads) J. Stat.…”

This paper studies the spatiotemporal evolution characteristics of trac dynamics at a crossroads which consists of two perpendicular one-lane roads, employing alternating update rules and periodic boundary conditions. Unlike in previous studies, the deterministic Nagel-Schreckenberg trac flow model is adopted in this work. Based on a close observation of the evolution near the upstream and downstream traffic flow at the crossing point, we have found typical periodically recurring sequences of vehicle motion configurations, and their specific characteristics depend on the value of the maximum velocity of vehicles and the vehicle densities on both roads. We have presented phase diagrams which consist of five basic regions. The flow formulas in these regions have been analyzed or derived. The results of theoretical analysis are in good agreement with the simulation results.
