Abstract: The increment in the traffic flow demand has forced transport planners to increase the number of lanes of highways in order to provide better functional and operational facilities to the users. Measures of effectiveness (MOE) of a road system is one of the critical issues faced in highway planning and management. Level of service (LOS) is a qualitative measures describing the operational condition of a transportation facility. The LOS concept devised by US-HCM is unfit for direct implementation in Indian heterogeneous mixed traffic condition. This is mainly due to the heterogeneous traffic conditions and vastly unique driver behavior found on Indian highways. Thus a well-defined LOS criterion for heterogeneous traffic condition is utmost necessary. The vehicles prevailing under heterogeneous traffic vary widely in static and dynamic nature. An attempt has been made in this study to define the LOS criteria per lane basis on multilane highways in terms of traffic density, considering the

Abstract: The deformation due to creep has an important effect on the behavior of concrete structures especially for their long term integrity. Undesirable consequences may appear in the structures due to incorrect or inaccurate prediction of creep deformation. A large database coming from international laboratories and research centers is used in order to compare the experimental results with the Eurocode 2 creep prediction. This study shows that the Eurocode 2 underestimates the important creep compliance and overestimates the small creep compliance. In order to overcome this inaccuracy, new correction coefficients are introduced to the formulas of the Eurocode 2 using an Approximate Bayesian Computation method based on the rejection algorithm.
