In this study, a car-following model is put forth to explain the behavior of HDVs (human-driven vehicles), AVs (autonomous vehicles) and CAVs (connected automated in mixed traffic. Based on IDM (intelligent-driver model) molecular dynamic theory, includes velocity surrounding vehicles along with difference headway between each pair vehicles. The drivers’ sensitivity deceleration nearest front v...

Here we present performance evaluation of different routing protocols such as SIFT, GPSR and GOSR using different mobility models like Fluid Traffic Model (FTM), Intelligent Driver Model and Random Waypoint Model (RWM) with Intersection Management (IDM-IM). We present simulation results that demonstrate the importance of choosing a mobility model in the simulation of a Vehicular Network Protoco...

Adaptive Cruise Control Systems (ACC) are becoming essential in developing advanced vehicular applications/services which help to reduce the risk of accidents and offer better conditions for comfort in the driving experience, Hartenstein and Leberteaux (2008). The IDM (Intelligent Driver Model) is a realistic car-following model whose main feature is the use of physical-oriented parameters to e...

Due to mobility constraints and high dynamics, routing is a more challenging task in VANETs. In this work, we evaluate the performance of the routing protocols in vehicular network environment. The objective of this work is to assess the applicability of these protocols in different vehicular traffic scenarios. Both the position-based and topology-based routing protocols have been considered fo...

With an increasing number of vehicles equipped with adaptive cruise control (ACC), the impact of such vehicles on the collective dynamics of traffic flow becomes relevant. By means of simulation, we investigate the influence of variable percentages of ACC vehicles on traffic flow characteristics. For simulating the ACC vehicles, we propose a new car-following model that also serves as the basis...

This paper presents a magnetostrictive in-pipe impact drive mechanism (IDM). To estimate the output performances of the IDM, a dynamics model was developed based on the magnetostrictive material constitutive model and mechanical model of the IDM. Therefore, an experimental system has been built to test the motion performance of IDM. Simulation and experimental results illustrate that the propos...

The impact of driving automation and adaptive cruise control (ACC) on traffic performance has been increasingly studied in recent years. This paper focuses two widely used ACC car following models investigates the time headway parameter operation one busiest freeway corridors Ontario, Canada. Using Aimsun microsimulation, we compare commonly models; intelligent driver model (IDM) Shladover’s wh...

This paper investigates the accuracy and robustness of car-following (CF) adaptive cruise control (ACC) models in reproducing measured trajectories commercial ACCs. To this aim, a general modelling framework is proposed, which ACC CF have been incrementally augmented with physics-based extensions: namely, perception delay, linear or nonlinear vehicle dynamics, acceleration constraints. has appl...
