Social navigation provides drivers with an advice that aims to shift traffic flows in a network from a user equilibrium to a system optimum. The advice is based on minimizing a combination of the individual travel time and the marginal total travel time in the network. The level of altruism defines the extent to which a driver is willing to sacrifice his own travel time in favor of other drivers....
Traffic congestion is a world-wide problem with far-reaching consequences. Due to road topology as well as driver behavior, extreme degrees of congestion can occur. Just as in biological swarms, stochastic properties of individual agents contribute to the emergence of macroscopic network properties. In this paper we apply approaches for swarm behavior to road traffic, expanding them to include road...
This brief deals with the improvement of a vehicle's pass-through of predictively known urban driving situations concerning its fuel consumption. Today's technology enables the prediction of information about traffic events. This information can be used to identify efficient driving strategies. The main aim is to reduce the dynamics in the velocity profiles of driving situations and with it the corresponding...
Eco-routing is the identification of the most energy-efficient route for a vehicle to travel between two points and is offered as a way in which drivers can reduce fuel consumption and consequently reduce the carbon footprint of their journeys. This paper covers the first step in the process of investigating the impacts of digital map attributes on the calculation of an eco-route. A research tool...
Speed and homogeneity of speed are important factors for safe and sustainable traffic. Lower speeds and more homogeneous speeds are safer and cause less pollution. Speed behavior is influenced by environmental factors as well as by personal factors. Understanding the relation between speed behaviour and the influencing factors offers clues for appropriate countermeasures against inappropriate and...
Road transportation is an essential component of the European economy. However, this sector is responsible for the increase of emissions and fuel consumption from year to year. Traffic incidents are one of the main causes of congestion. This paper has the main objective to calculate the consequences in traffic performance, fuel consumption and emissions that result from the occurrence of road incidents,...
Nowadays, more and more foreigners participate in vehicle driving test in order to get the driver's licenses in China. Because they are not familiar with China's road traffic safety laws or road conditions, part of them are often involved in traffic accidents. This paper is to discuss the important and difficult points of theory teaching in motor vehicle driving training for foreigners, as well as...
Rural highway traffic accident data collected by survey of 9 counties in 3 different provinces in China are studied. The studies show there are six special characters of rural highway traffic accidents. In rural highway the vehicle type is more complex and the large proportion of vehicle is unlicensed. Most accidents happened in 2 and 3 class road in rural area. The highway is in poor condition. The...
Service area is one of fundamental parts in freeway, an important mark to show freeway's perfection. Its disposition plays very important role in reducing the traffic accidents, optimizing the driving environment, raising the operational and social efficiency. The issue, which should be seriously considered during freeway plan and construction, is how to make facility disposition at service area suitable,...
This paper suggests a decision support system for vehicle drivers, accessible via mobile phone. Concept behind the system is to help drivers to schedule their activities, best utilizing their time along the way, minimizing the impacts of traffic. This is in contrast to existing approaches focused on controlling traffic in highways. Vehicle is continuously tracked along the journey and information...
Driver fatigue and sleep deprivation have been widely recognized as critical safety issues that cut across all modes in the transportation industry. FMCSA, the trucking industry, highway safety advocates, and transportation researchers have all identified driver fatigue as a high-priority commercial vehicle safety issue. There has been much research work done in driver fatigue detection. This paper...
In the lane change process, the different types of drivers have different behavior characteristics, the same driver in different road environments has not the same behavior, in order to design lane change model based on driver characteristics, it is necessary to study drivers' lane change characteristics. With real vehicle data, analyzed the lane change characteristics of the same driver on Beijing...
Traditional time-of-arrival estimation techniques are often used in advanced transportation systems such as in-car navigation systems and fleet management systems. These techniques tend to neglect certain categories of context when estimating a vehicle's time-of-arrival at a given destination. Particularly important categories of such neglected context include driver behavior patterns and traffic...
Small rural communities are often located along major state or county highways and as a result much of the traffic along their main thoroughfare is pass-through rather than local. Unfortunately, drivers passing through those communities often enter at high speeds and then maintain those speeds throughout creating a safety problem for the community. High speeds also discourage pedestrian activities,...
We propose a driver risk evaluation method based on the analysis of driving data captured with drive recorders. To evaluate the acceleration behavior of each driver we plot the maximum acceleration per minute to velocity on a two-dimensional plane and approximate the distribution by linear regression. We assume that the higher the y-intercept of the line, the quicker the driver accelerates from a...
Unexpected shift often occurs in the working of an automatic transmission. This paper analyzes the causes of this phenomenon and its influences on the heavy-duty vehicles' AT. The method of setting a reasonable shift delay interval and realtime detection on torque converter speed ration is proposed to solve this problem. The shift control strategy to eliminate unexpected shifts is designed and validated...
Based on a large number of experimental data, a simple construction method of driving cycle named fixed step intercept is used to construct the driving cycle of Hefei. In data processing, three definitions of running statuses are defined. The results and errors of different definitions of running statuses are analyzed through 11 characteristic parameters which reflect the road traffic characteristics...
This article systematically studies drivers' behavior pattern before accidents according to human's activities. In this study, a fuzzy logic control model is built which based on multiple regression theory, multi-objective decision theory and fuzzy logic control method, and practically proved. Results of model prediction preferably coincide with the practical analysis results from the scene. It proves...
Longitudinal slope section of the road is high frequency location of traffic accidents. In order to improve the road safety, the paper was based on the traffic engineering, applying psychology and other theories, and used the advanced GPS, MC5600 and other testing equipments to detect and investigate the road alignment, speed, driver's heart and physiological responses and traffic characteristics...
Vision-based driver assistance is an active safety measure currently under development in various car companies and research institutes worldwide. The paper informs about related activities at The University of Auckland, focussing on stereo vision, performance evaluation, provided test data, and currently developed components.
