Data mining technology is used to analyze the association between driver's macroscopic characteristics and accident types of drivers of urban traffic accidents. Based on the correlation between microscopic characteristics (such as physiology and psychology of the driver and macro characteristics (such as sex, age and driving age), the statistic values of driver sex, age and driving characteristics...
Enabling high-throughput and cost-effective vehicular communications is important for many emerging vehicular applications, such as safety applications, traffic management, and mobile Internet access. However, dedicated short-range communications (DSRC), as the sole solution so far, would meet significant challenges in the foreseeable future for supporting diverse vehicular applications simply due...
Based on NS model, a mixed traffic flow on single lane is simulated in the paper, which includes two-classification vehicles owing the different max-velocity. Take the one move 5 grids for one time as quick-vehicle, which is the results of aggressive behavior, such as overtaking and closely following behavior. And take the one which moves 3 grids for one time as slow-vehicle, which is on behalf of...
The purpose of analysis of conflicts within the urban intersection is to determine the degree of different types of conflicts within the intersection. Currently, the analysis of conflicts within urban intersections considers in general simply the conflicts between motorized vehicles and the influence of non-motorized vehicles and pedestrians is usually ignored. This paper summarizes the research findings...
An experiment was conducted in a fixed-base driving simulator to observe young drivers' their physiology changes under high mental workload, while responding to two sets of mental tasks: n-back and sound counting. 20 drivers (9 of them younger than 25 (range 21–24) and 11 older than 25 (range 29–33) were instructed to drive along two sections on a highway at a constant speed. NASA-TLX scores for workload...
In this paper, we present Vehicle Station Gateway (VSG) and Unified Gateway Protocol (UGP) for accessing vehicle bus data from smart car applications. They have been proposed and discussed as part of the ISO Standard Projects in ISO TC204 & TC22. We evaluate the feasibility of these approaches with a prototype implementation of vehicle trouble diagnosis and vehicle body network control applications...
The improved P-2D HMM is introduced to the driving intentions identification, and the driving intentions identification model based on continuous P-2D HMM was estabLished to identify the driving intention. The vehicle space, speed and lateral acceleration were as inputs, the driving intentions as output. Predict the driving behavior at next period to further enhance active safety. This paper choice...
The influence factors of freeway are analyzed in the paper according to the followings: drivers, vehicles, freeway and environments. And ICFCM algorithm is advanced to cluster the influence factors of freeway and get the influence level. In which, there are two improved way in ICFCM algorithm in initialize central and clustering effect. The results show that the iterations of ICFCM algorithm is reduced...
The relationship between the velocity discreteness ?? and the venture degree of vehicle rear-end accidents on freeway and urban road is researched by NS model. We could get the following as the results of simulation: Firstly, the value of global standard deviation of velocity on freeway is bigger than the one on urban road. Secondly, the value of venture degree of rear-end accidents is added as the...
Set a reasonable value of max-limited speed is an important part of traffic control. On the basis of systematically analyzing the information processing mode of driver and considered the performance differences of different vehicles, each kind of traffic information in work zone is classified and quantified and a calculation method of different vehiclespsila max-limited speed for work zone of highway...
The driver controlling model of car-following based on preview follower theory is advanced by analyzing the relation of direction controlling and velocity controlling on the following car and regarding the whole car-following course as preview-follow to the velocity of the leading car for n times. The model could describe the car-following behaviors more truly due to the safety decision index is the...
