We propose to research the problem of detecting and preventing imminent collisions between buses and pedestrians. GPS and inertial sensor measurements will be fused to analyze bus motion, and other sensors, such as laser scanners, will detect pedestrians in danger. Appropriate algorithms will be developed to anticipate collisions, and warn the driver and pedestrians through various channels. On...

This article discusses a pedestrian detector for an experimental vehicle, based on visual information from a single far infrared camera. The system considers three consecutive processes for each image. Once the candidates’ heads have been extracted, regions of interest are resized based on the distance to the camera and then filtered by its vertical edges symmetry. Once the bounding boxes of po...

We apply the genetic algorithm technology in the traffic control system and pedestrian crossing to provide intelligent green interval responses based on dynamic traffic load inputs, thereby overcoming the inefficiencies of the conventional traffic controllers. We apply such technology to a four-way, two-lane junction based on two sets of parameters: vehicles and pedestrians queues behind a red ...

For the simulation of pedestrians a method is introduced to find routing alternatives from any origin position to a given destination area in a given geometry composed of walking areas and obstacles. The method includes a parameter which sets a threshold for the approximate minimum size of obstacles to generate routing alternatives. The resulting data structure for navigation is constructed suc...

The aim of this short note is mainly pedagogical. It summarizes some knowledge about Boolean satisfiability (SAT) and the P=NP? problem in an elementary mathematical language. A convenient scheme to visualize and manipulate CNF formulae is introduced. Also some results like the formulae for the number of unsatisfied clauses and the number of solutions might be unknown. Introduction. Specificall...

We review the results of the Standard Model Higgs boson search at LEP. An emphasis is put on revealing the details behind the statistical procedure developed by the LEP Higgs working group. The procedure is explained using a toy model which allows the reader to estimate the significance of the experimental observation which led at the time to a scientific debate on whether LEP has observed a 11...

This paper analyzes pedestrians’ behavioral patterns in the pedestrianized shopping environment in the historical center of Barcelona, Spain. We employ a Bluetooth detection technique to capture a large-scale dataset of pedestrians’ behavior over a one-month period, including during a key sales period. We focused on comparing particular behaviors before, during, and after the discount sales by ...

Pedestrian detection and tracking remains a popular issue in computer vision, spawning many applications in robotics, surveillance and security, biometrics and humancomputer interaction. In this paper we present a biological framework for detecting and tracking pedestrians by using a monocular moving camera. This framework is based on visual cortex cells, namely complex and end-stopped cells, t...
