  • analyses of pedestrian behavior on mid block unsignalized crosswalk comparing chinese and german cases
    Advances in Mechanical Engineering, 2015
    Co-Authors: Xiaobei Jiang, Wuhong Wang, Klaus Bengler, Weiwei Guo
    Abstract:

    A large number of pedestrian fatalities are caused by the vehicle-pedestrian accidents. The application of new theory and technological approaches may hold great potential to reduce the accident frequency and severity for pedestrians. Considered the different driving cultures between China and Germany, the adaptation of such application in new market triggers an “Intercultural Comparison” related to the road user behavior and traffic safety. Field traffic data have been collected by video recording and image processing at unsignalized mid-block crosswalks both in Beijing, China and Munich, Germany. Centered Vehicle-Pedestrian conflict situation, pedestrian speed performance in different pedestrian categories and walking phases, pedestrian waiting behavior related to waiting decision choice and waiting time, pedestrian gap acceptance were statistically analyzed for understanding the pedestrian behavior in the conflict process. Intercultural Comparisons were made between China and Germany. The research results addressed how the conflict participants (pedestrians only) behave differently and would hopefully be the impetus for further Intercultural analyses from urban traffic side.

  • Intercultural analyses of time to collision in vehicle pedestrian conflict on an urban midblock crosswalk
    IEEE Transactions on Intelligent Transportation Systems, 2015
    Co-Authors: Xiaobei Jiang, Wuhong Wang, Klaus Bengler
    Abstract:

    In traffic conflict techniques, time-to-collision (TTC) is suggested to be a surrogate measure of conflict severity. In order to address the differences in conflict situation between driving cultures, field traffic data have been collected by video recording and image processing at urban midblock crosswalks both in Beijing, China, and Munich, Germany. Focusing on the vehicle–pedestrian (VEH-PED) conflict, by identification of field observation, conflict situation, and TTC calculation, a trajectory-based data matrix is created for understanding the entire conflict process. TTC distribution and relationships between TTC and PED/VEH-based parameters are investigated with Intercultural Comparison. Special cases in China, where traffic noncompliance is common, are also studied as a complement to normal VEH-PED conflicts. The research will hopefully lay the groundwork in the target of providing advanced driver assistance system adaptation databases in the future.

  • Intercultural Comparison of road user behavior centered vehicle pedestrian conflict in urban traffic
    2012
    Co-Authors: Xiaobei Jiang
    Abstract:

    As vulnerable road users, pedestrians are easily involved in traffic accidents on urban crosswalk where the motor vehicle-pedestrian conflicts typically occur. Nowadays, the Advanced Driver Assistance Systems (ADAS) may hold great potential to reduce the accident frequency and severity by providing guidance or appropriate actions to the drivers. Considered the different driving cultures between China and Germany, design of ADAS for new and growing market in China triggers an “Intercultural Comparison” related to the road user behavior and traffic safety. This study aims to the fundamental theories of road user behavior in motor vehicle-pedestrian (VEH-PED) conflict and analyze the main road user behavioral characteristics based on the real traffic data, which can be applied to conflict behavior modeling and traffic safety evaluation. Video observation and image processing are employed at seven field study sites in Beijing, China, and Munich, Germany, the data series of road user trajectories in conflict situation are studied to form the standard data matrix. The microscopic data including pedestrian behavioral parameters, driver behavioral parameters and situational factors are investigated. The study tries to address how the conflict participants behave differently between China and Germany, and gives a view of Intercultural Comparison on conflict behavior. The Intercultural analyses are carried out mainly in the following aspects: From the macroscopic level Urban traffic situation Comparison Pedestrian safety situation Comparison Driving culture Comparison From the behavioral level Differences in pedestrian conflict behavior Speed performance Waiting performance Gap acceptance Time-related measures and their relationships Differences in driver conflict behavior Driver yielding behavior Driver deceleration rate and its relationships with other parameters TTC-related relationships Special case analysis Non-compliance conflict situations in China According to the observation data, model predicting the driver yielding behavior on basis of binary logit model and model calibrates the pedestrian waiting behavior on basis on Weibull distribution are proposed and verified to be effective. Two conflict indicators, the minimum VEH-PED distance and critical conflict radius are mathematically introduced for conflict discrimination. The measures to improve traffic safety on unsignalized crosswalk in China are discussed through traffic control and design, traffic facility, traffic education and law enforcement. The research would lay the groundwork in the target of creating ADAS adaptation data base and it will hopefully be the impetus for further Intercultural analyses from urban traffic side. The objective of this research is to address the differences of the road user behavior between China and Germany, and to create the situation-countermeasure relationships for analyzing the road users’ reaction in traffic conflicts. Video observations and image processing are employed during field data collection in Beijing and Munich. On basis of the trajectory analyses, the data matrix including pedestrian behavioral parameters, driver behavioral parameters and situational factors are investigated. Hopefully the work will give impulses for Intercultural adaptation of Advanced Driver Assistance Systems. © Copyright 2012 Xiaobei JIANG

  • The Behaviour of Managers in Austria and the Czech Republic: An Intercultural Comparison Based on the Vroom/Yetton Model of Leadership and Decision Making*
    Journal for East European Management Studies, 2004
    Co-Authors: Gerhard Reber, Werner Auer-rizzi, Milan Maly
    Abstract:

    In this paper we compare the leadership behaviour of managers in Austria and the Czech Republic, employing the Vroom/Yetton situational leadership model. The model applies a methodology that is close-to-action in contrast to the collection of empirical data based on questionnaires, which target the revelation of basic values as determinants of Intercultural differences (farfrom-action), such as the studies of Hofstede and the GLOBE-Project. The results show that leadership behaviour in the Czech Republic remains autocratic despite dramatic changes in the societal and political environment of the two countries. In diesem Aufsatz vergleichen wir das Fuhrungsverhalten von Managern in Osterreich und der Tschechischen Republik anhand des Vroom/Yetton situationsbezogenen Fuhrungsmodells. Das Modell nutzt eine Methodik, die praktisch ist im Vergleich zur Sammlung von empirischen Daten, die auf Fragebogen basieren und welche die Enthullung von Grundwerten als Determinanten von interkulturellen Unterschieden (theoretisch) wie die Studien von Hofstede und das GLOBE-Projekt zum Ziel hat. Die Ergebnisse zeigen, dass dass Fuhrungsverhalten in der Tschechischen Republik immer noch autokratisch ist, trotz dramatischer Veranderungen sowohl im sozialen als auch im politschen Umfeld in beiden Landern.

  • The Leadership Behaviour of Managers in Austria, the Czech Republic and Poland: An Intercultural Comparison Based on the Vroom-Yetton Model of Leadership and Decision Making
    Change Management in Transition Economies, 2003
    Co-Authors: Gerhard Reber, Werner Auer-rizzi
    Abstract:

    This chapter uses the Vroom-Yetton situational leadership model to compare the leadership behaviour of managers in Austria, the Czech Republic and Poland. The model applies a methodology that is ‘close to action’, in contrast to the collection of empirical data based on questionnaires that use basic values as determinants of Intercultural differences (‘far from action’). The results show that leadership behaviour in the Czech Republic and Poland remains autocratic despite dramatic changes in the societal and political environments of the two countries.
