This paper focuses on the design of adaptive cruise control (ACC) which was implemented on a passenger car based on sliding mode control (SMC) of throttle valve combining with fuzzy logic control of brake pedal. An important feature of the new adaptive cruise control system is the ability to maintain a proper inter-vehicle gap based on the speed of host vehicle and headway way. There are three ...

1 VISSIM roundabout models have been widely applied in practice to facilitate analyzing the 2 operational performance of roundabouts. To prepare a VISSIM roundabout model for analysis, 3 an essential prerequisite is to calibrate the model by adjusting parameters until real-world 4 roundabout operations are reproduced in the simulation model. Previous calibration research has 5 used qualitative ...

We evaluated the effects of prompting, goal setting, and feedback on following headway of young drivers in a simulated driving environment and assessed whether changes produced in following headway were associated with reductions in hard braking when drivers were and were not using cell phones. Participants were 4 university students. During baseline, drivers spent half of the time talking on c...

We consider a one-dimensional vehicular network where the time headway (time difference between successive vehicles as they pass a point on the roadway) follows the shifted-exponential distribution. We show that neglecting the impact of shift in the deployment model, which degenerates the distribution of vehicles to a Poisson Point Process, overestimates the temporal correlation of interference...

A safe headway to the lead vehicle is important reduce conflicts with merging vehicles from highway on-ramps. Previous research has outlined advantage of gap metering strategies yield sufficient space and improve capacity during peak hours. However, prevailing systems fail indicate minimum required leave it drivers’ judgment adjust their headway. This paper proposes a new Active Gap Metering (A...

To retain and attract new riders, transit agencies are frequently in search for ways to improve system reliability. Transit agencies typically operate several routes that partially or fully overlay (or overlap) one another in order to offer a better service coverage to reach various destinations. While previous research has focused on understanding the general factors that impact headway adhere...

This paper addresses the study of some appropriate control strategies in order to guarantee the exponential stability of a class of deterministic microscopic car-following models including human drivers' memory effects and automated headway controllers. More precisely, the delayed action/decision of human drivers is represented using distributed delays with a gap and the considered automated co...

We present two collections of lexical items with idiosyncratic distribution. The collections document the behavior of German and English bound words (BW, such as English headway), i.e. words which can only occur in one expression (make headway). BWs are a problem for both general and idiomatic dictionaries since it is unclear whether they have an independent lexical status and to what extent th...

A microscopic traffic model is presented which employs differences in velocity to characterize driver behavior. The Intelligent Driver (ID) based on an acceleration constant cannot capture different conditions. Further, it not physics and so can produce inaccurate results. proposed improved ID both are evaluated a 2000 m circular road. results obtained show that the appropriately flow density. ...
