Demographic Background

A lot of crashes involving heavy vehicles have been reported over the years in Kerala. Faulty driving behavior is widely regarded as the major cause of such crashes. This study considers the drivers’ perceptions and their socio-demographic background to understand the behavioral variations. The study is done based on a questionnaire survey on public transport operators from which their behavioral characteristics are noted. The study area is divided into three parts namely, North, Central and South Kerala with a fixed sample at each of these regions. The sample size is fixed based on Bill Godden’s method for infinite population. Accordingly, a sample of 384 vehicles was surveyed from each region. Thus, data for a total of 1,152 public transport vehicles were taken from all three regions namely North, South, and Central Kerala. From this sample, the variations in violations, errors and lapses among drivers are noted based on various causative factors. Analyses of these behavioral factors are done to study the influence on aberrant behavior and accident occurrence in public transport vehicle plying in Kerala. A linear regression model is developed to state the importance of causative factors in the occurrence of crashes.

The potential effects of implementing longer and heavier vehicles (LHVs) in road freight transport have been studied in various countries, nationally and internationally, in Europe. These studies have focused on the implementation of LHVs on certain types of commodities and the experience from countries like Finland and Sweden, which have a long tradition of using LHVs, and in which LHVs used for all types of commodities have not been widely utilised. This study aimed to assess the impacts of long and heavy vehicles on various commodities in the United Kingdom based on the Finnish experiences in order to estimate the possible savings in road freight transport vehicle kilometres, costs, and CO2 emissions in the United Kingdom if LHVs would be introduced and used similarly to in Finland in the transport of various commodities. The study shows that the savings of introducing longer and heavier vehicles in the United Kingdom would be 1.5–2.6 billion vehicle kms, £0.7–1.5 billion in transport costs, and 0.35–0.72 Mt in CO2 emissions. These findings are well in line with previous findings in other countries. The results confirm that considerable savings in traffic volume and emissions can be achieved and the savings are very likely to outweigh possible effects of modal shift from rail to road.

Modern Era

Today’s modern era life style is famous for its unhealthy lifestyle, improper sleep pattern, stressful life and so on, the reasons are uncountable so as the diseases, creating a high profile lifestyle with significant nega-tive shift in health status which creates even more serious reasons to combat the pathology behind. Ayurve-da is an age old time-tested system of traditional medicine that comes with even more deep rooted three fold fundamental approach Nidan Parivarjana (avoidance of causative factors), Shodhan (biocleansing treatment modality) and Shaman (palliative treatment). Shodhan mainly comes under the broader terminol-ogy Panchakarma, may seem quite simple in its application yet creates effects that are powerful and long-lasting, very famous for its approach for various ailments, especially chronic disorders. As the name sug-gests Panchakarma comprises five therapeutic procedures namely Vamana, Virechana, Nasya, Basti and Raktamokshana. It acts as a bio servicing mechanism for the human body just like the regular servicing of the transport vehicle. In the present piece of work, Vaman Karma has been described w.s.r. to its im-portance as a therapeutic regime to eliminate toxins, acting as a biopurificatory technique to maintain and obtain health; and to remove ailments, a concept of prevention over intervention. Some concepts like mode of action, importance of Shodhanarth Sneh, etc; has also been discussed deeply to understand the working action behind them.

Time Required

The review of the literature devoted to the research of public transport vehicle (PTV) dwell time required for passenger boarding-deboarding at a stop confirms the importance of taking this time into account when modelling passenger transportation. The data about the dwell time were collected in different time periods for different PTVs in various cities and countries. Thus, there is no general model allowing to define the distribution parameters of dwell time variable and answer the question on the regularities in time values. So, the research of the PTV dwell time at the public transport stops in Kharkiv remains actual. Goal. The search of the regularities in transport system performance indicators including PTV dwell time at a stop will allow to apply relevant mathematical methods for the development of the forecast models which are valuable in the field of organization of passenger transportation and servicing. Methodology. The developed methodology to collect data about PTV dwell time at the stops will allow receiving high-quality survey data. The designed survey sheets enable a surveyor to record all needed information and prepare it for processing. The collected data will allow to define the distribution of the PTV dwell time at a stop. Results. The conducted PTV dwell time survey allowed to collect the sufficient amount of data to estimate the distribution of this variable. During the research, it was determined that the empirical dwell time distribution can be well described with the theoretical gamma distribution. The latter distribution appeared to be applicable for all surveyed PTVs. Originality. The defined distribution of the PTV dwell time at a stop for passenger boarding-deboarding allows receiving the results of passenger flows modelling which are more precise compared to the modelling with no dwell time consideration. The use of the dwell time regularities in the procedure of passenger flows assignment results in the increased precision of flow volumes estimation by up to 14.9 % – from 2.28 % to 1.94 %. Practical value. The received results support the fact that the research of PTV dwell time at a stop is actual, and the solution of the task of dwell time distribution estimation will make it possible to improve passenger flows modelling in public transport route systems.
