From the literature it was studied that the multiple linear regression models established by many researchers to determine PLoS evolved with addition or removal of one or more physical parameters or with respect to the perception of users from different locations. At an intersection, there is little or no established methodology developed so far to determine a quantitative approach for PLoS similar to Vehicular Level of Service (VLoS). It was also pointed out that under heterogeneous traffic conditions, pedestrians are most vulnerable at intersections and they share the same space with motorized vehicles for crossing movements. Methodology: Thus, this study was built on the hypothesis that pedestrian delay of a signalized intersection is quantitatively dependent on pedestrian volume, vehicular volume and cycle time. Two signalized intersections operating as fully actuated a...

It is supported with Adaptive Cruise Control, Automatic Emergency Brake, blind spot monitoring, lane change assistance, and forward collision warnings etc. It is an important platform to integrate these multiple applications by using data from multifunction sensors, cameras, radars, lidars etc. and send command to plural actuators, engine, brake, steering etc. ADAS technology can detect some objects, do basic classification, alert the driver of hazardous road conditions, and in some cases, slow or stop the vehicle. The architecture of the electronic control units (ECUs) is responsible for executing advanced driver assistance systems (ADAS) in vehicle which is changing as per its response during the process of driving. Automotive system architecture integrates multiple applications into ADAS ECUs that serve multiple sensors for their functions. Hardware architecture of ADAS and autonomo...

This would form a basis of appreciating the travel pattern with respect to mode of transport used, purpose, cost, frequency and length of travel according the different categories of socioeconomic groups. In this paper, the existing travel pattern by the various socio-economiccategories of people were appreciated clearly in quantitative terms with the examination of the various transport related policy and strategy options to ascertain the degree of public transport to be developed for creating a conducive environment of better public transport travel condition by developing Modal Split model using Fuzzy Logic. The primary aim of the study was to explore ways and means with the help of transport policy options to quantify and reduce the green house gas emitted from the transport sector with the change modal split in favor of public transport. In order to demonstrate how to estimate the above gas from the travel pattern of Newcastle city, a small sample data of 248 commuters were collected in the year 2005 mostly traveling by car and public transport using bus and metro. Further an attempt has been made to study the travel characteristics for two types road users traveling by car and public transport. The approach demonstrated here would provide a basis for estimation of green house from the data collected from the transportation study conducted in 2005, 2011 and 2021. I. Background Climate change resulting from the growing carbon foot print in the world is one of the burning issues threatening the survival of mankind. Transport sector is also responsible for generation of significant amount of green house gas of the order of 22 percent per annum (1) as compared to the other man made activities in the world. Apart from the emission of green house gas, there are a number of other air pollutants emitted from transport sector, also causing a great deal of problems to human health. The SECURE (Self Energy Conserving Urban Environment) project through the approach of 4 M dealing with " Measurement, Modelling, Mapping and Management of air pollution data with a primary focus on estimation of carbon footprint, undertaken by the UK partners comprising of five academic universities has initiated to examine various issues of the emission of green house gas caused due to the large scale generation of human made activities in UK. The SECURE (2) project addresses the grand challenge of integrating greater conservation and more efficient resource utilisation across scales to meet future urban demands It is increasingly felt that personalized mode of motorized vehicles is the cause of major pollutant, responsible to account for significant amount of not only in terms of the emission of green house gas but also responsible for generating other air pollutants, a serious concern for human health. It has led us to believe that the greater use of public transport can help bring down the green house gas. Therefore it is extremely important to assess the role of transport sector in relation to the generation of green house gas. In this context, an attempt has been made to study the existing travel pattern of Newcastle City with a small of data set, UK. Further analysis with a large set of data of 60,000 records of household would attempt to ascertain the characteristics of various parameters of travel of various socioeconomic categories of people. This would form a basis of appreciating the travel pattern with respect to mode of transport used, purpose, cost, frequency and length of travel according the different categories of socioeconomic groups. Once the existing travel pattern by the various socioeconomic categories of people are understood clearly in quantitative terms, then one can examine the various transport related policy and strategy options to ascertain the degree of public transport to be developed for creating a conducive environment of better public transport travel condition. Therefore a study of mode choice modeling would be an appropriate option in context of SECURE project. Finally one can quantify the magnitude of carbon emission with the detailed understanding of mode choice behavior of different categories of socioeconomic groups of people not only for the present situation of travel characteristics but also help understand the quantum of generation of green house gas to be generated under different policy and strategy options in future.
