    Travel time information is a vital component of many intelligent transportation systems (ITS) applications. In recent years, the number of vehicles in India has increased tremendously, leading to severe traffic congestion and pollution in urban areas, particularly during peak periods. A desirable strategy to deal with such issues is to shift more people from personal vehicles to public transport b... View full abstract»

    A novel approach for recognising various traffic sign shapes in outdoor environments is presented. To reduce the influence of digital noise and extract the shape of each individual traffic sign, the external boundaries of traffic signs segmented based on colour information are simplified and decomposed through discrete curve evolution whose stop stage is determined by an arc similarity measure in ...

    The development of electronic vision systems for the automotive market is a strongly growing field, driven in particular by customer demand to increase the safety of vehicles both for drivers and for other road users, including vulnerable road users (VRUs), such as pedestrians. Customer demand is matched by legislative developments in a number of key automotive markets; for example Europe, Japan a... View full abstract»

  • Local traffic condition: improvement of a vehicle-based measurement approach

    Publication Year: 2009, Page(s):32 - 41
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (457 KB)

    Advanced driver assistance systems (ADAS) can be designed to adapt to the driver's current needs, for example, taking the traffic conditions in the immediate vicinity of the ego vehicle into account. This motivates the design of a system intended to measure the local traffic conditions in a way, which corresponds to the driver's perception of traffic conditions. A new method of measurement is intr... View full abstract»

  • Pedestrian detection using a singlemonochrome camera

    Publication Year: 2009, Page(s):42 - 56
    Cited by:  Papers (4)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1096 KB)

    A car-mounted single monochrome camera-based pedestrian detection algorithm is discussed. The detection range is divided into two sub-regions, that is, the near distance range and the far distance range. Two different detection algorithms are applied in the two regions. For the near distance range, where the direction of the motion of the detected obstacle is important, a motion segmentation appro... View full abstract»

    The availability of Global Navigation Satellite Systems (GNSS) enables sophisticated vehicle guidance and advisory systems such as intelligent speed adaptation (ISA) systems. In ISA systems, it is essential to be able to position vehicles within a road network. Because digital road networks as well as GNSS positioning are often inaccurate, a technique known as map matching is needed that aims to u... View full abstract»

  • Self-adapting traffic flow status forecasts using clustering

    Publication Year: 2009, Page(s):67 - 76
    Cited by:  Papers (1)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (655 KB)

    A key problem for the efficient use of stationary traffic prediction models is that for adaptation to new data they require human-made re-calibration with a new database. So far, there has been a lack of knowledge of how to develop a practical prediction model that would learn while working online. Anyone providing real-time traffic information and making forecasts of the traffic situation could b... View full abstract»

  • Estimation of travel time using fuzzy clustering method

    Publication Year: 2009, Page(s):77 - 86
    Cited by:  Papers (1)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (346 KB)

    A methodology to estimate overall travel time from individual travel time measurements within a time window is presented. To better handle data with complex outlier generation mechanisms, fuzzy clustering techniques have been used to represent relationships between individual travel time data collected within a measuring time window. The data set is considered to be a fuzzy set to which each data ... View full abstract»

    Cited by:  Papers (20)  |  Patents (1)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (422 KB)

    Field measurements from the GSM and UMTS networks are analysed in a road traffic information context. The measurements indicate a potentially large improvement using UMTS signalling data compared with GSM regarding handover location accuracy. These improvements can be used to generate real-time traffic information with higher quality and extend the geographic usage area for cellular-based travel t... View full abstract»

    Research undertaken by the Transportation Research Group at the University of Southampton is discussed, which studies the views, needs and requirements of local authorities as users of sensor grids for environmental monitoring. The study was undertaken through a combination of literature review and workshop activity. Representatives from local authorities were invited to participate in a workshop ... View full abstract»
