This paper proposes a map generation algorithm for a precise roadway map designed for
autonomous cars. The roadway map generation algorithm is composed of three steps …

Urban areas are currently facing new and enormous challenges: urbanization, connected
and automated land and air transport with new demand for transport and logistic services …

Periodic recreation of existing railway horizontal alignment geometry is needed for
smoothing the deviations arising from train operations. It is important for calibrating track and …

Currently, pedestrian networks are not as widely available as road networks are for many
areas; this is partly due to the high demand for applications such as car navigation …

Aggressive driving, amongst all driving behaviors, is largely responsible for leading to traffic
accidents. With the objective to improve road safety, this paper develops an on-line …

Analyzing the distance visible to a driver on the highway is important for traffic safety,
especially in maneuvers such as emergency stops, when passing another vehicle or when …

This article proposes a new method for fitting the horizontal alignment of a road to a set of (x,
y) points. Those points can be obtained from digital imagery or GPS‐data collection. Unlike …

A major problem of vertical alignment recreation is to automatically attribute the measured
points to geometric elements (ie, grades and vertical curves) and to efficiently recreate the …

The primary objective of this research effort was to compare roadside data collected by
typical manual methods–on foot and often requiring traffic control–to data collected by …

ABSTRACT Global Positioning System (GPS) devices afford the opportunity to collect
accurate data on unit movements from temporal and spatial perspectives. With a special …
