The Influence of Trucks on Traffic Flow — An Investigation on the Nagel–schreckenberg-Model

Abstract: A few years ago Nagel and Schreckenberg introduced a model for traffic flow, 1 which, though quite simple, is able to reproduce the basic properties of traffic. Meanwhile many variations of the model have been developed, part of them concentrate on introducing an inhomogenous fleet of cars with different maximum velocities.Here we also want to study the effect of introducing a certain fraction of vehicles with a lower maximum velocity ("trucks") to the Nagel-Schreckenberg-model. We give a detailed description … Show more

“…d. Agent-based simulations exhibit fluctuations; this can be of advantage if one wants to include fluctuations into the simulation. However, there are a number of challenges: a. Agent-based simulations scale quadratically (or with some other exponent larger than 1) with the number of individuals involved, e.g., if each individual gets the chance to interact with any other individual [7][8][9]. b. Agent-based simulations exhibit fluctuations; this can be a disadvantage if one is interested in average values.…”

“…Many specialized studies have investigated the road running characteristics attributable to large vehicles. Related research mainly analyzed the bottleneck effect of large vehicles from the microscopic theory and obtained some generally accepted conclusions [4][5][6][7][8][9][10][11]. In 1992, Gazis and Herman [4] proposed a mobile bottleneck concept for vehicle queuing caused by slow vehicles on low-speed roads and proposed a mobile bottleneck model for symmetric lane changing in two-lane highways.…”

“…In the simulation of nonuniform traffic flow with mixed fast and slow cars, the existence of a slow train was found to have a significant influence on the traffic flow. Ebersbach et al [6] used the NS model to add trucks into passenger car flow. Trucks were found to have a significant impact on singlelane traffic characteristics, but this effect was negligible for high-density vehicles, and the impact of trucks could be completely ignored for low-density traffic flow or low truck ratios.…”

“…Jia et al, Ebersbach et al, and Xiao et al used the heterogeneous CA model to study the impact of trucks on traffic flow. They studied the influence of vehicle length, truck percentage, and maximum speed on the system performance [20][21][22]. For the existing CA models, when modelling heterogeneous traffic flow, they only give different characteristic parameters (e.g., vehicle length, acceleration, and maximum speed) for different vehicle types, but the update rules are still the same.…”
