“…In addition to smart vehicles, intelligent traffic management (ITM) is also of great importance to smart mobility. In cities, especially megacities, roads play a leading role in transportation [27]. Therefore, researchers and city officials have been very interested in studying road maintenance as a significant aspect of urban infrastructure.…”

In recent years, customized buses (CBs), a new form of public travel mode between bus and car, has sprung up in China. Its characteristics include flexible routes, each person having a seat and point-to-point travel have attracted travelers who seek high-quality travel, especially car travelers, alleviating traffic congestion at peak periods and leading to a change in urban travel modes. In addition to providing new travel modes, an exclusive bus lane (EBL) is also an effective means to alleviate traffic congestion. Therefore, this paper establishes link impedance functions under mixed travel modes considering the EBL, including customized buses on different kinds of links, and then presents a day-to-day dynamic traffic flow assignment model based on stochastic user equilibrium (SUE). Some conclusions were summarized by numerical case studies. First, the parameter of travelers’ sensitivity to route travel time affects the speed of traffic flow evolution. When it increases to positive infinity, the final state of the traffic network moves from SUE to deterministic user equilibrium (DUE). Second, the parameter on the degree of dependence of travelers on previous experience can not only influence the value size of actual travel time, but also influence the direction of actual travel time evolution. Third, conventional buses and customized buses have higher transportation efficiency than cars, but if the proportion of conventional bus travelers is too large, the total travel time of all travelers in the traffic network may increase. Fourth, when travel demands increase, the proportion of travelers who choose public transit is required to increase to achieve minimum total travel time. Lastly, from the perspective of the whole traffic network in any case, the EBL is not always beneficial. It is recommended to set EBLs when conventional buses and customized bus flows are heavy, which can be judged based on the model established in this paper.

Rigid pavements are often used on clay soils with long-term settlement history and are subject to damage from traffic loads. It must be analyzed for deflections in rigid pavements built on clay to prevent damage and extend pavement life. If deflection exceeds the permit, the pavement will experience damage. One way to minimize these problems is by installing vertical drains to improve the soil. Installing a vertical drain on the soil can increase the modulus of the subgrade reaction represented as soil- bearing capacity and minimize the potential for pavement deformation. This research aims to analyze the deflection of rigid pavement on clay soil with vertical drains. The finite element method is utilized to analyze the deflection. The pavement is modeled as a 10 m long and 7 m wide slab with thickness variations ranging from 150 mm to 350 mm. Static loads are used to model vehicle loads with load positions at the pavement’s center, ends, and edges. For all slab thicknesses subjected to varying center, end, and edge loads, the maximum deflection of rigid pavement over vertical drain soils is lower than that of soils without vertical drains. It can be concluded that rigid pavement deflection can be reduced using vertical drains for soil improvement.

The article defines the importance of organizing road traffic in urban transportation systems. The research targets are defined and all its key elements and characteristics are identified. The research target is a segment of the North-Western Chord of Moscow corresponding to Bolshaya Akademicheskay Street in the Koptevo District and limited by Mikhalkovskaya Street and 3rd Nizhnelikhoborskiy Proyezd. The research resulted in a model of a transport system graph for the area under study delineating traffic and pedestrian flows. The model takes into account the points of conflicts in crossing and merging of flows. The research findings became the basis for a mathematical model of traffic in problematic spots of the area under study. Conclusions are made as to the suitability of the findings and their use in the smart city system.
