Purpose The trajectory of a vehicle is comprehensively affected by the interactions between the vehicle, the driving behavior, and the road environment. High-risk driving behaviors and accident-prone road sections can be identified based on the relationship between the trajectory and road geometry. Previous related studies mostly focused on the trajectory deviation at a few points on the road, ...

To make driving assistance system more humanized, this study focused on the prediction and assistance of drivers' perception-response time on mountain highway curves. Field tests were conducted to collect real-time driving data and driver vision information. A driver-vision lane model quantified curve elements in drivers' vision. A multinomial log-linear model was established to predict percept...

answered calls while driving a simulator. Calls were answered using a center-console-mounted phone or one of several phone designs which utilized a HUD to display the caller ID and steering-wheel-mounted buttons to activate the phone. Driving workload was manipulated by varying the curve radius and by varying the timing of the call, either 1 second before or 5 seconds after the start of a curve...

In this paper, we proposed a road extraction algorithm that utilises voxel-based skewness and kurtosis balancing in order to update existing road networks accurately and reliably from airborne lidar data. The proposed algorithm consists of initial road extraction followed by a series of refinements including width constraints, spatial interpolations and curve fitting which are successfully impl...

present study is an extension of earlier work carried out on two-lane two way roads in the two provinces of pakistan i.e. n-25, n-55 and n-5 regarding the measure of operating speed and development of operating speed prediction models. curved sections of two-lane rural highways are the main location of run-off road accidents. in addition to that the road alignment having combination of geometri...

monitoring of road traffic noise is becoming an important issue in modern cities due to the spreading of noise pollution and the extension of monitored areas. thus, the stratified spatial sampling is frequently applied to reduce the costs and provide adequate accuracy in order to obtain reliable noise maps. the definition of the strata in the sampling may refer to the legislative classification...

The recent advances in computer visualization methods have made it possible to exploit the possibility of applying scientific visualization methods in critical research areas in the field of transportation engineering. In this paper we develop new visualization methods for road design and safety. Typically, roads are designed by combining horizontal and vertical roadway alignments, to allow for...

So far path coverage problem has been studied widely to characterize the properties of the coverage of a path or a track in an area induced by a sensor network, in which the path or track is usually treated as a curve and the width of it can be ignored. However, sensor networks often are employed to carry out road surveillance or target tracking, in which the interesting area is only the surfac...

We introduce a new scheme for safety message authentication in VANETs. For a practical implementation of VANET, we anticipate that road side units (RSUs) are not physically protected and are prone to several different attacks including node compromise attacks. Thus, an RSU should not be automatically trusted by on road vehicles. In our proposed scheme, a road side controller (RSC) is responsibl...

The project MARVin is about assessing the relation between road infrastructure and road accidents. A large amount of data about the Austrian roads was gathered with the RoadSTAR (Road Surface Tester of arsenal research). This data was put into a database associated with accident data. The result was a database of about 12.500 km of road where all the road parameters (skid resistance, cross fall...
