Driving fatigue is one of the main reasons of resulting in heavy traffic accident and is an important part of accident risk. Road scene is one of the main exogenous factors contributing to fatigue. Design rationality of road scene plays an important role in reducing the influence of driving fatigue. We use video image processing technique and video image compressing technique to research the relation...
In this paper we present an approach for a central ego motion estimation with standard and near-series sensors for advanced driver assist systems. The two main contributions of this article are the provision of all variables relative to the road surface and the fusion of several sensors and perception modules providing information of ego localization. Thus we employ a discrete Kalman filter to consider...
One opportunity to manage the increase of freight transportation and to optimize utilization of motorway capacities is the concept of truck platoons. With the aid of Advanced Driver Assistance Systems, trucks are electronically coupled keeping very short gaps (approx. 10 meters) to form truck platoons on motorways. This contributes to optimization of traffic flow and reduction of fuel consumption...
Utilizing advanced technologies to guarantee safety protection for pedestrians at intersections has become an important issue because intersections are the places where pedestrians easily conflict with vehicles. The purpose of this study is to propose a conceptual design of an intersection bus-pedestrian collision warning system with appropriate detection and warning parameters for bus drivers approaching...
This paper describes the development of a mid-line detection system on curve road as guidance for drivers to stay center in road-lane they are currently on using simulation model. The system will identify the curve road and detecting the tangent for each segmented curve. The purpose of detecting the tangent is to find a point that is normal to tangent of the curve. Then, using pixel distance calculation,...
The driver assistance system is more and more widely used with the development of automobile industry. The driver assistance system based on pervasive computing integrates the function of computing, communicating and sensing, which can assure the driving safety and prejudging the traffic emergency by sharing the information among vehicles of the same district. The structure and working principle of...
The environment perception and driver assistance (.enpeda..) project searches for solutions for vision-based driver assistance systems (DAS) which are currently starting to be active safety components of cars (e.g., lane departure warning, blind spot supervision). We review current projects in .enpeda.. in the international context of developments in this field.
Driver inattention is the leading factor in most crashes and near-crashes. If the driver distraction could be measured as soon as possible, crashes should be decreased. Driver distraction research has assessed the effects of various different devices and activities on numerous driving performance measures. Some typical methods that have been used to measure driver distraction have been discussed in...
During the last few years many Advanced Driver Assistant Systems have been developed and a larger number of new car models every year is going to be equipped with these systems. However the product/function scenario lacks of common evaluation methodologies and tools for testing and improving performances of these systems. In this paper a validation methodology and a tool for Traffic Sign Recognition...
We introduce a real-time weather notification system in which drivers are notified with any bad weather conditions on the road including icy conditions or foggy conditions. Different type of bad weather requires different type of detection. We combine all cases by placing sensors uniformly to the road with an intelligent vehicles that communicate with the surrounding vehicles and the road itself....
In this paper, a brief introduction of automated truck platoons on motorways is given. It includes a description, of the scenario ??platoons organized by the driver??, the system architecture of the platoon system and a description of the software architecture for a driver information system. The results of the accomplished system and acceptance tests of the platoon system in the truck driving simulator...
Taxi service has undergone radical revamp in recent years. In particular, significant investments in communication system and GPS devices have improved quality of taxi services through better dispatches. In this paper, we propose to leverage on such infrastructure and build a service choice model that helps individual drivers in deciding whether to serve a specific taxi stand or not. We demonstrate...
This study presents a new method of analyzing whether a vehicle is in a dangerous driving condition while travelling along a highway. We use data from various sensors installed on the vehicle, which represent the driving attributes associated with a particular driving scenario, as inputs to our system. However, as some of these sensors may be dependent on each other, using redundant attributes to...
The motivation of this paper is to propose a simple and reliable method to identify on-road vehicle events, particularly in the driving situations. A content rhythm is extracted by applying a virtual line lies on the same position of each frame. Thereupon a simplified representation of a continuous video is to record the temporal information of vehicle status. Thus, vehicle situations such as lane...
New driver assistance systems can have consequential effects on traffic flow. Investigative simulations are necessary for the design, optimization and evaluation of these assistance systems. Previous calibration and validation methods utilized either microscopic or macroscopic measurement data.This paper's purpose is to argue that the formerly held calibration and validation perspectives with regard...
Advance Traveller Information Systems (ATIS) are considered a promising tool to alleviate traffic congestion and improve road network performance. They provide real time traffic information and route recommendation to road users, in order to increase their ability to choose the best alternative path. Though such systems have reached a high technical standard, their actual impact in traffic pattern...
This paper investigates the fusion of digital maps and dynamical models to accurately predict the future path of a vehicle. This path prediction is generated by a vehicle for sharing with other vehicles through wireless communication channels. This sharing is an enabler of Vehicle-to-Vehicle (V2V) cooperative systems. In particular, this work looks at cooperative safety and comfort systems, which...
This paper presents a real-time implementation on lane detection and tracking system in order to localize lane boundaries and estimate a linear-parabolic lane model. It is realized using TMS320DM642 DSP board. Video frame is first captured with CCD camera and stored in video port buffer. Next, input image is split into sky and road region with horizon localization. Lane analysis is applied on the...
Car navigation systems are now widely used as a component for intelligent transportation systems. Route planning is the most important task of car navigation systems. Though modern car navigation systems incorporate various road information, even dynamic information, to generate optimal route, but they are yet to present routes according to driver's requirements or preferences. Most of the car navigation...
To prevent crashes of automobiles, many driver assistance systems have been proposed. Several warning systems have been proposed to reduce driver cognitive and judgment load. Such warning systems should have ability to evaluate collision risk and to start warning appropriate timing. Inversely, the system's efficacy can be decreased if the driver feels annoyance and/or mistrust with inappropriate warning...
