Scene classifier for real time road detection

L’objectiu principal del projecte és el de classificar escenes de carretera en funció del contingut de les imatges per així poder fer un desglossament sobre quin tipus de situació tenim en el moment. És important que fixem els paràmetres necessaris en funció de l’escenari en què ens trobem per tal de treure el màxim rendiment possible a cada un dels algoritmes. La seva funcionalitat doncs, ha de ser la d’avís i suport davant els diferents escenaris de conducció. És a dir, el resultat final ha de contenir un algoritme o aplicació capaç de classificar les imatges d’entrada en diferents tipus amb la màxima eficiència espacial i temporal possible. L’algoritme haurà de classificar les imatges en diferents escenaris. Els algoritmes hauran de ser parametritzables i fàcilment manejables per l’usuari. L’eina utilitzada per aconseguir aquests objectius serà el MATLAB amb les toolboxs de visió i xarxes neuronals instal·lades.

IPH response to consultation: Introduction of 20mph speed restrictions on smaller residential streets

Conall McDevitt (SDLP MLA) launched a consultation regarding the introduction of 20mph speed restrictions in residential streets as part of his bid to introduce legislation through a Private Members Bill in the Northern Ireland Assembly.  The purpose of the Bill is to increase road safety, particularly for pedestrians and other road users, with additional health and environmental benefits. IPH submitted a response to the Private Members’ Bill regarding the introduction of 20mph speed restriction on smaller residential roads.  IPH recognises the potential public health benefits of this proposal in terms of reduced injuries and fatalities in built up areas; more opportunities for walking and cycling (helping to tackle obesity and reduce the risk of diabetes, heart disease and stroke); greater social cohesion among communities and improved mental health; and reduced emissions that contribute to climate change, air and noise pollution.

IPH response to Road Safety Authority Ireland Road Safety Strategy 2013-2020

The Road Safety Authority has responsibility for co-ordinating the development of Ireland’s Road Safety Strategy.  The Government’s road safety target of no more than 252 deaths per annum by the end of 2012 was achieved in 2009, when the number of road collision deaths in Ireland fell to 239.  The reduction in the number of fatalities was achieved through robust actions in terms of education and awareness, road engineering, and enforcement, including significant legislative milestones.  The challenge is now to ensure that the impact of these measures on collision levels is sustained and enhanced into the future through continuous education, enforcement and road engineering measures and initiatives. IPH welcomes the opportunity to respond to this consultation given the significant burden of injury, disability and mortality associated with road traffic collisions on the island of Ireland.  IPH supports the development of evidence-based strategies and actions which can maintain a transport system, in which the safety of all road users is paramount. 

IPH response to DOE Consultation 'Preparing a Road Safety Strategy for Northern Ireland 2010-20'

The Department of Environment (NI)  recently held a consultation on preparing a new road safety strategy for Northern Ireland which will cover the years 2010 to 2020.  The consultation ran from 16 March 2010 to 15 June 2010.  The consultation paper outlined key challenges to be addressed over the lifetime of the strategy and proposed a number of action measures which have been agreed by the statutory road safety partners.  Views were invited on preparing a new road safety strategy for Northern Ireland that will shape the way ahead for safety on roads over the next decade.

A Folk Theorem for Games when Frequent Monitoring Decreases Noise

This paper studies frequent monitoring in an infinitely repeated game with imperfect public information and discounting, where players observe the state of a continuous time Brownian process at moments in time of length _. It shows that a limit folk theorem can be achieved with imperfect public monitoring when players monitor each other at the highest frequency, i.e., _. The approach assumes that the expected joint output depends exclusively on the action profile simultaneously and privately decided by the players at the beginning of each period of the game, but not on _. The strong decreasing effect on the expected immediate gains from deviation when the interval between actions shrinks, and the associated increase precision of the public signals, make the result possible in the limit. JEL: C72/73, D82, L20. KEYWORDS: Repeated Games, Frequent Monitoring, Public Monitoring, Brownian Motion.

Effect of a Road Safety Training Program on Drivers' Comparative Optimism

Reducing comparative optimism regarding risk perceptions in traffic accidents has been proven to be particularly difficult (Delhomme, 2000). This is unfortunate because comparative optimism is assumed to impede preventive action. The present study tested whether a road safety training course could reduce drivers' comparative optimism in high control situations. Results show that the training course efficiently reduced comparative optimism in high control, but not in low control situations. Mechanisms underlying this finding and implications for the design of road safety training courses are discussed.

The Road to Recovery: A New Approach to Tackling Scotland's Drug Problem

The Scottish National Drugs Strategy requires the 22 regional Drug Action Teams to prepare and submit to the Scottish Executive annual action plans for tackling drug misuse in their areas. These plans should address national and local priorities, including their contribution to the achievement of national targets. These comprise three parts: Part A provides an overview of the DAT structures and working; Part B provides detailed information on current local services and Part C reports plans for 2003/04.This resource was contributed by The National Documentation Centre on Drug Use.

Quality assurance in road traffic analyses in Switzerland.

Swiss laboratories performing toxicological road traffic analyses have been authorized for many years by the Swiss Federal Roads Office (FEDRO). In 2003 FEDRO signed a contract with the Swiss Society of Legal Medicine (SSLM) to organize the complete quality management concerning road traffic analyses. For this purpose a multidisciplinary working group was established under the name of "road traffic commission (RTC)". RTC has to organize external quality control, to interpret the results of these controls, to perform audits in the laboratories and to report all results to FEDRO. Furthermore the working group can be mandated for special tasks by FEDRO. As an independent organization the Swiss Center for Quality Control (CSCQ) in Geneva manages the external quality controls in the laboratory over the past years. All tested drugs and psychoactive substances are listed in a federal instruction. The so-called 'zero tolerance substances' (THC, morphine, cocaine, amphetamine, methamphetamine, MDMA and MDEA) and their metabolites have to be tested once a year, all other substances (benzodiazepines, zolpidem, phenobarbital, etc.) periodically. Results over the last years show that all laboratories are generally within the confidence interval of +/-30% of the mean value. In cases of non-conformities measures have to be taken immediately and reported to the working group. External audits are performed triennially but accredited laboratories can combine this audit with the approval of the Swiss Accreditation Service (SAS). During the audits a special checklist filled in by the laboratory director is assessed. Non-conformities have to be corrected. During the process of establishing a new legislation, RTC had an opportunity of advising FEDRO. In collaboration with FEDRO, RTC and hence SSLM can work actively on improving of quality assurance in road traffic toxicological analyses, and has an opportunity to bring its professional requests to the federal authorities.

The high road and the low road: trafficking choices in plants.

Polar transport of the signaling molecule auxin is critical for plant development and depends on both the polar distribution of auxin efflux carriers, which pump auxin out of the cell and the alignment of these polarized cells. Two papers in this issue of Cell (Michniewicz et al., 2007; Jaillais et al., 2007) address how polar transport of these carriers occurs and describe the endosomal pathways involved.

Be fit or be sick: peroxisome proliferator-activated receptors are down the road.

Investigating metabolism by unveiling the functions of the nuclear receptors peroxisome proliferator-activated receptors (PPARs) in the numerous intricate pathways ensuring energy homeostasis and fitness has been extremely rewarding. Major lines of research were initially determined by the first-characterized crucial roles of PPARalpha in fatty oxidation and of PPARgamma in adipocyte differentiation and lipid storage. Today, the molecular bases of the functional links between glucose, lipid, and protein metabolism, under the important but nonexclusive control of PPARalpha and PPARgamma, are starting to be uncovered. In addition, in the last couple of years evidence has been provided for an important role of PPARbeta (delta) in lipid metabolism. Inevitably, such actors of metabolic homeostasis are implicated in the physiopathology of complex metabolic disorders, such as those constituting the metabolic syndrome, resulting in atherosclerosis and cardiovascular diseases. This review presents a summary of the recent findings on their dual involvement in health and disease.

Practical signal-to-noise ratio quantification for sensitivity encoding: Application to coronary MR angiography.

Purpose: To develop and evaluate a practical method for the quantification of signal-to-noise ratio (SNR) on coronary MR angiograms (MRA) acquired with parallel imaging.Materials and Methods: To quantify the spatially varying noise due to parallel imaging reconstruction, a new method has been implemented incorporating image data acquisition followed by a fast noise scan during which radio-frequency pulses, cardiac triggering and navigator gating are disabled. The performance of this method was evaluated in a phantom study where SNR measurements were compared with those of a reference standard (multiple repetitions). Subsequently, SNR of myocardium and posterior skeletal muscle was determined on in vivo human coronary MRA.Results: In a phantom, the SNR measured using the proposed method deviated less than 10.1% from the reference method for small geometry factors (<= 2). In vivo, the noise scan for a 10 min coronary MRA acquisition was acquired in 30 s. Higher signal and lower SNR, due to spatially varying noise, were found in myocardium compared with posterior skeletal muscle.Conclusion: SNR quantification based on a fast noise scan is a validated and easy-to-use method when applied to three-dimensional coronary MRA obtained with parallel imaging as long as the geometry factor remains low.
