Current driver assistance systems are not all-weather capable. They offer comfort and safety in sound environmental conditions. However, in adverse weather conditions where the accident risks are highest they malfunction or even fail. Now that we are progressing towards automated cars and work machines, the requirements of fully reliable environment perception are only accentuated. The project is focusing on automated driving and its key enabling technology, environment perception. Consequently, projects main objective is to develop and validate an all-weather sensor suit for traffic services, driver assistance and automated driving. Extended driving environment perception capability with smart, reliable and cost-efficient sensing system is necessary to meet the targets of all future driver assistance system applications. These targets need to be met regardless of location, weather or time of the day. Only by means of reliable and robust sensing system upcoming automated driving will be possible. The new sensor suit is based on a smart integration of three different technologies: (i) Radio radar, 77 GHz-81 GHz, (MIMO Radar); (ii) Gated short wave infrared camera with pulsed laser illumination (SWIR camera)and (iii) Short-wave infrared LIDAR (SWIR Lidar). Such a full fusion approach has never been investigated before, so that the outcome will advance the state-of-the-art significantly and demonstrate the potential of all-weather environment perception. DENSE innovation lies in the provision of a brilliant restored enriched colour image from a degraded infrared image and consequently, this is followed by a variety of application fields for low cost solutions. An important aim is also to close the gap to US developments in the field and avoid their restrictions for selling components overseas for strategic reasons and strengthen the position of European industry in worldwide competition.

Cost effective multi-wavelength light sources are key enablers for wide-scale penetration of gas sensors at Mid-IR wavelength range. Utilizing a novel Mid-IR Si-based photonic integrated circuit filter and wide-band Mid-IR SLEDs, we aim at demonstrating an innovative light source that covers 2.73.5 m wavelength range with a resolution < 1nm. The spectral bands are switchable and tuneable and they can be modulated. The source allows for the fabrication of an affordable multi-band gas sensor with good selectivity and sensitivity. The unit price can be lowered in high-volumes by utilizing tailored molded IR lens technology and automated packaging and assembling technologies. In safety and security applications, the Mid-IR wavelength range covered by the source allows for the detection of several harmful gas components with a single sensor. The project is filling a gap: affordable sources are not available. The market impact is expected to be disruptive, since the devices currently in the market are either complicated, expensive and heavy instruments, or the applied measurement principles are inadequate in terms of stability and selectivity. At the foreseen price level, the proposed approach is extremely competitive against conventional gas sensors. The source will be validated in several key applications including building ventilation, high voltage asset monitoring, emission monitoring, gas leakage monitoring as well as process control and safety. The consortium is composed of one large European company, three SMEs, and three world-class research organisations from three European countries representing the complete value chain from devices and components to gas sensor manufacturers. The position of these organizations in their respective markets guarantees that the project results will be widely exploited providing the companies with a technological advantage over their worldwide competitors thus creating new high-tech jobs and technology leadership in Europe.

Cities face a number of key transport challenges in the 21st Century. Congestion has a set of well-documented negative consequences, including environmental pollution, poor economic competitiveness, low levels of public satisfaction with public transport, negative impacts on personal health and wellbeing, and a broader reputational impact on urban centres that aspire to be retail and tourist destinations. Moreover, the UKs commitment to reduce carbon emissions necessitates a broader long-term shift away from private motor transport towards low carbon and mass transit modes of transport. In this way, tackling the specific issue of urban congestion relates to wider social and economic goals for cities to become better places to live and easier places to navigate. Specifically, Exeter has some of the worst air pollution and congestion statistics for a city of its size. Yet the city is also witnessing unprecedented expansion of outlying suburbs, creating greater pressure on existing arterial and city centre roads. Alongside these background factors, the city aspires to maintain its position as a key retail and tourist centre and there are plans to redevelop several areas of the city centre for retail and leisure facilities in the coming years. One of the ways in which social scientists have attempted to deal with this wicked policy problem is to promote pre-formed behavioural change through the provision of information and exhortations to individual travellers to change their behaviour. However, decades of social research has illustrated that influencing behaviour is highly complex and requires a significant investment in research intelligence about what influences travel behaviours. Although recent years have witnessed a growth in social marketing approaches for influencing change, which adopt the methods of conventional marketing approaches, a set of factors that have been largely omitted from such studies and interventions is the role of what can be termed real time factors in travel decision making, which are not pre-formed, but which influence practices in the moment. Research intelligence from traffic management providers suggests that factors such as weather conditions, immediate levels of traffic congestion and perceptions of the effectiveness of public transport are all important to consider when understanding both decisions to travel and also the resultant behaviour of travellers on their journeys (either as drivers or public transport users). Indeed, crucial to understand are the ways in which these conditions can be communicated to promote different practices, either as decisions to travel using different modes or to drive in a different way, and the potential for harnessing new technologies for managing travel behaviour through both the utilisation of sophisticated traffic management systems. This research therefore aims to understand and promote better real time travel decision making through adopting a personalised and tailored travel behaviour approach. This will be undertaken through a two stage methodology. In stage 1, a large general survey of Exeter residents and those travelling into Exeter on a daily basis will be undertaken to explore key travel behaviours, attitudes, participants characteristics. Using an online survey approach, the questionnaire will enable researchers to both identify key segment groups and their travel behaviours and, on the basis of these analyses, to make high level statistical links between individual behaviours and external factors, including quantitative information from other datasets. In stage 2, a panel of representative participants from the segments identified at stage 1 will be formed to explore the key relationships between behaviours and specific interventions that will be captured through a series of experiments, which will test interventions and their effectiveness.

The present invention concerns a method and system for gas concentration measurement of gas or gas mixtures dissolved in liquids. A gas or gas mixture dissolved in a liquid sample is extracted from the liquid sample using an extraction system and conducted into a measurement chamber. Then a measurement signal is generated by means of a radiant source and the measurement signal is directed to a measurement object in a measurement chamber containing the gas or gas mixture to be measured. The measurement signal is filtered using at least two wavelengths, whereupon the filtering is preferably implemented by means of an electrically tunable, short-resonator Fabry-Perot interferometer. Then the filtered measurement signals are detected my means of a detector.
