The rapid growth of private car ownership and utilization has resulted in significant parking-related congestion problems at large-scale international airports. Parking facilities located in the peripheral areas of airports could be more efficiently used to mitigate congestion and reduce delays due to dramatically increasing traffic demands and inferiorly designed parking lot configurations. In order to analyze the travelers' parking choice preferences for the off-site airport parking activities, a stated preference survey study was conducted around Terminal 3 at Beijing Capital International Airport. Two nested logit models were formulated to analyze the correlation between travelers' parking behavior and their travel characteristics. The research results indicate that travelers prefer to choose off-site parking facilities for long-term parking. A free and fast operation of connections should be provided in consideration of the long-distance layouts of parking facilities. A classification analysis of travelers with different preferences was conducted and the potential changes in travelers' parking choices to off-site parking lots were quantified. The research findings are helpful for traffic management agencies to develop practical guidelines for the establishment of new parking facilities with multiple access points at airports.

Abstract: Measurements of cross sections of the 95Mo(n, α)92Zr reaction at E n=4.0, 5.0 and 6.0MeV were carried out at the 4.5MV Van de Graaff of Peking University, China. A twin gridded ionization chamber and two large-area 95Mo samples were adopted. Fast neutrons were produced through the D(d, n)3He reaction by using a deuterium gas target. A small 238U fission chamber was employed for absolute neutron flux determination. Present data are compared with existing evaluations and measurement. [Copyright &y& Elsevier]

Abstract: Cross sections of the 147Sm(n, α)144Nd reaction were measured at En=5.0 and 6.0MeV. A twin gridded ionization chamber was used as a charged particle detector and two large area 147Sm2O3 samples placed back to back were employed. Experiments were performed at the 4.5MV Van de Graaff accelerator of Peking University. Neutrons were produced through the D(d, n)3He reaction with a deuterium gas target. Absolute neutron flux was determined by a small 238U fission chamber. Present cross-section data are compared with existing results of evaluations and measurements. [Copyright &y& Elsevier]
