Numerical exploration of freeway tunnel effects with a two-lane traffic model

SIMULATION (2022)

Zhengming Li M.N. Smirnova Yongliang Zhang Н.Н. Смирнов Zuojin Zhu

To explore freeway tunnel effects on ring road traffic flow, a two-lane traffic model is put forward. The model adopts lane-changing time to describe the net lane-changing rate, assuming that the time is approximately equal to the relaxation time of traffic flow, but infinite when the absolute value of difference of traffic density between the two lanes is lower than 1 veh/km, as it is hard for car drivers to perceive such a small difference. Based on the two-lane traffic model, a simulation platform is built to predict traffic flow on a two-lane freeway ring with a tunnel of 0.3 km length having a speed limit of 80 km/h, and free flow speeds on lane I and II equal to 120 and 100 km/h, respectively. The platform uses a third-order Runge–Kutta scheme to handle the time derivative term, and a fifth-order weighted essentially non-oscillatory scheme to calculate numerical flux. Simulation results show that the freeway tunnel can trigger traffic shock originating at the entrance when the coming flow density is beyond a traffic density threshold that is dependent on the off-ramp flow just upstream the tunnel. The occurrence of traffic shock leads to the mean travel time through the tunnel is almost a constant when the initial density normalized by jam density is less than 0.5. When initial density is above the density threshold, generally vehicles need more fuel consumption to run through the ring road in comparison with the case without tunnel. But the situation is just the opposite for larger normalized initial density such as 0.5.

Unsteady-state Traffic Flow Models for Urban Regulation Strategy Planning

M.N. Smirnova A. I. Bogdanova Nickolay Smirnov А.Б. Киселев В. Ф. Никитин

The present research aims mathematical modeling of essentially unsteady-state traffic flows on multilane roads, wherein massive changing of lanes produces an effect on handling capacity of the road segment. The model uses continua approach. However, it has no analogue with the classical hydrodynamics, because momentum equations in the direction of a flow and in orthogonal directions of lanehanging are different. Thus, velocity of small disturbances propagation in the traffic flow is different depending on direction: counter flow, co-flow, orthogonal to the flow. Numerical simulations of traffic flows in multilane roads were performed and their results are presented. Massive changing of lanes produces an effect on handling capacity of the road segment. Mathematical models allow describing the conditions for maximal road handling capacity, the origination and propagation of traffic humps and jams, the influence of various traffic control devices, and transverse evolution of traffic flows on multi-lane roads.
