Stochastic Approximation Simulation for Highway Vertical Curves Elements

摘要

The goal of this study is to examine a stochastic approximation technique for simulation of highway vertical curve elements by using Microsoft Excel 2010 program. The program is general purpose application software and in graphical user interface. Stochastic approximation simulation method established here is approached thus for reducing modeling-development time and towards getting inexpensive design methodology. The vertical curve elements of highway for investigation in this study are parabolic curves. The basic concept presented here is how to move progressively toward realisation of the best-value stochastic approximation algorithm for the development of vertical curves while providing adequate sight distance leading to the ability to see ahead on highway for safe, comfort and efficiency operation of a vehicle. Stochastic approximation simulation work is described in this study as a result of greater emphasis on automation modeling via Information Communication Technology (ICT) to improve productivity and quality of analysis and design of complex system such as highway. It is pertinent to note that alternative proposed vertical curves during design stage can be compared through stochastic approximation simulation modeling analysis methodology based upon an authentic policy for geometric design of highways and streets. Hence, a successful optimal system to meet specified requirements conforming to able policy on geometric design of highways and street has been established in this study via Microsoft Excel 2010 similarly like conventional hand method.
