Managing the increasing traffic is a big problem all over the world. Intelligent Transportation System (ITS) provides solution to these problems with the help of new technologies. ITS is an integrated system that implements a broad range of communication, control, vehicle sensing and electronics technologies to solve and manage the traffic problems. ITS is being used in the developed countries since past two decades, but it is still a new concept when developing countries like India, Brazil, China, South Africa etc. are concerned. In the present study we have studied four major parts of the ITS i.e., Advanced Traveler Information System (ATIS), Advanced Traffic Management System (ATMS), Advanced Public Transportation System (APTS), and Emergency Management System (EMS). Objective of the paper is to study various ITS architecture and model and review such models to get in-depth of their architecture. Hence architecture and developed models over the years of four major branches of ITS have been reviewed here to make a comparison analysis of different models that have been developed by the researchers in their studies. It will lead to the gaps in the knowledge which can be further studied. The paper highlights the conclusions extracted from the studies of different systems and also gives the future scope in the field of ITS to make it more user friendly and accessible.

The present study aims at studying ageing characteristics of conventional bitumen, polymer modified bitumen (PMB) and warm mix asphalt (WMA) by using FTIR. Results of obtained FTIR spectrum were quantified by calculating different indices and finally based on these indices ageing index of the binders for short- and long-term ageing were calculated. Results showed ageing increased amount of complex and high molecular weight components of the binders. PMB was found to have greater ageing resistance than conventional asphalt binders. In case of WMA, results found to be inconclusive, requiring further investigation.

Cold mix asphalt (CMA) has many economic and environmental benefits but its higher moisture susceptibility reduce its use to minor construction and repairing work. To increase the field implementation of CMA, it is very necessary to reduce its moisture susceptibility. So present study examines the effect of lime and cement filler on the moisture susceptibility of CMA. In the study, lime and cement fillers were used in varying proportions i.e. 1% to 5%. Based on volumetric properties and minimum emulsion content criteria, 2% was found to be optimum content for both lime and cement fillers. From Marshall stability, retained Marshall stability, Indirect tensile strength, and Tensile strength ratio values it was found that both fillers considerably improve moisture susceptibility of cold mixes. Energy consumption and cost comparison further concluded that as compared to HMA, incorporation of cement and lime fillers in cold mixes results in economic and environment-friendly mixes.

This study evaluates the creep and recovery response of different asphalt binders in unaged and short-term aged conditions. The multiple stress creep and recovery (MSCR) test has been carried out from 40 to 70°C at five different stress levels. Two conventional, two polymer-modified, and two warm mix asphalt binders were used. Polymer modification led to improvement in permanent deformation characteristics of the asphalt binders. The use of zycotherm as a warm mix additive did not have any positive effect on the creep and recovery response. The temperature susceptibility of the asphalt binders increased with ageing and stress levels. The variation of $J_{nr}$ with temperature and stress levels was quantified using a simple equation, whose parameters have been discussed in this paper. A simple correlation between aged and unaged values of $J_{nr}$ and $E_r$ is also established. Results from Fourier transform infrared spectroscopy (FTIR) and analysis of MSCR data indicated polymer degradation at higher temperatures because of short-term ageing, which affected the rutting characteristics of the polymer-modified binders.
