“…The proposed analysis complements and must be taken into considerations for all the studies on traffic flow behaviors. In particular, many studies (also based on bifurcation theory, see, e.g., [31][32][33]) consider how the traffic flow is affected depending on different driver's characteristics, without checking the lateral stability of each driven vehicle.…”

In this paper, we show that even an extremely simple nonlinear vehicle and driver model can show complex behaviors, like multi-stability and sensible dependence on the initial condition. The mechanical model of the car has two degrees of freedom, and the related equations of motion contain the nonlinear characteristics of the tires. The driver model is described by a single (nonlinear) equation, characterized by three parameters that describe how the driver steers the vehicle. Namely such parameters are the gain (steering angle per lateral deviation from desired path), the preview distance, and the reaction time delay. Bifurcation analysis is adopted to characterize straight ahead motion at different speeds, considering separately the two cases of understeering or oversteering cars. In the first case, we show that at suitable speeds the model can have three different attracting oscillating trajectories on which the system can work and that are reached due to different disturbances. In the second case, we confirm that instability arises if the forward speed is too high. The final results of the paper, bifurcation diagrams, can be used for many considerations critical both from the theoretical and from the practical viewpoints

“…Hence, drivers have to stop approaching the crossing points, which may trigger a traffic wave and last until pedestrians cross. As a result, drivers may slow down proactively on approaching a crossing point in anticipation of a pedestrian crossing maneuvers, particularly if there is a pedestrian platoon waiting by the roadside [46,111]. Moreover, it is observed that the waiting time of pedestrians at zebra crossings reduces by increasing the number of pedestrians at crosswalks [94].…”

“…It also affects drivers' behaviors on approaching a road segment with no pedestrian facilities. For example, drivers who are familiar with a road segment are likely to drive cautiously in anticipation of pedestrians' unexpected crossing attempt [111], whilst the pedestrian behavior may be surprising for those who are not familiar and can lead to conflict [46].…”

Negotiation and Decision-Making for a Pedestrian Roadway Crossing: A Literature Review

The interaction among pedestrians and human drivers is a complicated process, in which road users have to communicate their intentions, as well as understand and anticipate the actions of users in their vicinity. However, road users still ought to have a proper interpretation of each others’ behaviors, when approaching and crossing the road. Pedestrians, as one of the interactive agents, demonstrate different behaviors at road crossings, which do not follow a consistent pattern and may vary from one situation to another. The presented inconsistency and unpredictability of pedestrian road crossing behaviors may thus become a challenge for the design of emerging technologies in the near future, such as automated driving system (ADS). As a result, the current paper aims at understanding the effectual communication techniques, as well as the factors influencing pedestrian negotiation and decision-making process. After reviewing the state-of-the-art and identifying research gaps with regards to vehicle–pedestrian crossing encounters, a holistic approach for road crossing interaction modeling is presented and discussed. It is envisioned that the presented holistic approach will result in enhanced safety, sustainability, and effectiveness of pedestrian road crossings.

“…Furthermore, Deng et al [28] defined a new approach of anticipation based on the leader-follower form and modelling the anticipation effect by introducing an anticipation coefficient measuring the level of anticipation under actual driving conditions. Moreover, a new model of traffic flow is proposed by Yi-Rong et al [29]. They considered the effect of anticipation parameters corresponding to the individual differences in the traffic flow stability.…”
