The perception of Bus Rapid Transit: a passenger survey from Beijing Southern Axis BRT Line 1

Bus Rapid Transit (BRT) has emerged as a cost-effective transport system for urban mobility. As a relatively new form of Mass Transit, its ability to provide a high-quality transport service and potential to stimulate land development remain largely unexplored. This study intends to investigate the public attitude towards BRT services, as well as respondents’ perception of living near BRT stations, using the Beijing Southern Axis BRT system as a case study. A data-set of responses to 525 questionnaires were assembled and analysed using a combination of statistical techniques. The results show that BRT has gained great popularity among passengers, and brought about a positive impact on the attractiveness of residential property. The data identify that the majority of passengers are work-related commuters and use BRT more than once a day. The captive users have a higher satisfaction than choice users with respect to reliability, comfort & cleanliness and overall satisfaction with the BRT service. It is argued that the BRT has significantly improved the attractiveness of residential property along the BRT corridor.     

Experimental research on the mechanical properties of gypsum breccia with different water content

This paper deals with the influence of water content on the mechanical properties of gypsum breccia with different initial water contents. The experimental research was taken on the GDS (geotechnical digital systems) tri-axial experiment system by strain rate control. The mechanical properties,including stress-strain curves,peak deviator stress,relative residual strength,elastic modulus,Poisson's ratio,angle of internal friction and cohesion of gypsum breccia,were studied by experiment. The results showed t...
