Abstract: Over the past few years there has been increased installation of non-traversable un-signalized median openings in most of the urban regions in India. The motive behind this installation is to eliminate problems associated with illegal U-turns at intersections and other traffic facilities close to the median openings on multi-lane urban roads. Data collected for this study is in the form of video-images of six U-turn median openings on 4-lane and 6-lane roads situated in the cities of Bhubaneshwar, Rourkela and Ranchi located in the eastern part of India. This paper introduces a new concept on merging behavior of U-turn vehicles for evaluation of gaps accepted by drivers at median openings based on the “INAFOGA” method; which is further compared with the critical gap values obtained by and Macroscopic Probability Equilibrium concept for heterogeneous traffic flow in the urban region of the Indian states. IBM-SPSS 22.0 has been used to perform a paired-sample Hypothesis (t-test) between

Abstract: In this work, Duplex Coating (Plasma Nitriding + PVD Arc TiN coating) as well as non duplex (PVD TiN) coating has been carried out on substrate i.e. Mild Steel (MS). The substrate material was chosen because Mild steel has wide applications especially in Marine Engineering, Oil & Gas Production & Transmission industry as well it is a cost effective material. Surface Characteristics/Properties were investigated on PVD Titanium Nitride (TiN) Coated and Duplex Coated (Plasma Nitrided + PVD TiN) by Scanning Electron Microscopy (SEM), Energy Dispersive Spectroscopy (EDS), Micro Hardness Test and Rockwell Adhesion Test. Duplex coated samples (Plasma Nitrided + PVD TiN coated) showed better Mechanical Properties like Higher Hardness and higher Adhesion strength compared to their non-duplex (PVD TiN coated) counterparts, hence more suitable to be used in Mechanical applications.
