Abstract

We have developed a tool to design car body shapes. It enables any user even with no experience and skill to design car body shapes interactively and easily. We report how we synthesize car body shapes by following process. Firstly, we create a database of existing cars and analyze all shapes in the database using Principal Component Analysis (PCA). Secondly we extract attributes that indicate the geometrical features of those car body shapes. The attributes are then mapped onto the Eigen space obtained as a result of analysis. We construct a GUI in which the distribution of the attributes on the Eigen space is visualized. By manipulating the weight of each attribute on our GUI, we can synthesize car body shapes which nobody has ever seen.

A smart car control model for brake comfort based on car following

This paper demonstrates a novel car-following model focused on passenger comfort, for example, a rapid deceleration will make passengers uncomfortable. The brake comfort model of car following was set up according to the relationship between vehicle ...
Do drivers change their manual car-following behaviour after automated car-following?
Abstract
There is evidence that drivers’ behaviour adapts after using different advanced driving assistance systems. For instance, drivers’ headway during car-following reduces after using adaptive cruise control. However, little is known about whether, ...
Introduction of car sharing into existing car fleets in microscopic travel demand modelling

Microscopic travel demand models take the characteristics of every individual person of the modelled population into account for computing the travel demand for the modelled region. Car sharing is an old concept, but the combination of a car sharing ...
