A personalized driver assisting system that makes use of the driver's behavior model is developed. As a model of driving behavior, the Probability-weighted ARX (PrARX) model, a type of hybrid dynamical system models, is introduced. A PrARX model that describes the driver's vehicle-following skill on expressways is identified using a simple gradient descent algorithm from actual driving data collected...
Based on the analysis of the car-following time, a car-following time model was founded. After the analysis of speed variation, the model of speed random variable was founded, after that an improved highway capacity model was set up, and a calibrating method of the model was given, then, to simulate the model based on the actual data, and to analyze the influence of the free speed and the maximum...
The street network of a city is a dynamic entity in continuous change. Sometimes change can be seen as 'per-manent', sometimes as 'temporary.' New streets or changes to existing streets can be seen as permanent. Signal malfunctions, potholes, accidents change the capacity of the network can be seen as a temporary change. The dynamic nature of the network requires a tool to model and analyse it; while...
In this paper we will build a computer traffic model simulating movement of each individual vehicle through the traffic network and the interactions of that vehicle with other vehicles and semaphores (an agent-based model). It will model a simple traffic network (a two-way coordinated semaphore system a.k.a. "green wave") to test certain hypotheses on different kinds of semaphore systems...
Rapid prototyping allows for evaluation of design product in a short period of time. Designers or CEOs may perceive the size and appearance of the product by touching the automatically constructed physical objects produced through rapid prototyping. However, it is usually impossible to change its color, texture, and user interface. In this paper, we introduce 'Augmented Reality based Re-formable Mock-up',...
