Pedestrian is one of the important component in the urban transportation system and also vulnerable at unprotected mid-block locations under mixed traffic conditions. Crossing by pedestrians on midblock sections of urban roads is very common in developing countries such as India. The locations where the pedestrians cross the road are invariably undesignated with no pedestrian cross marks. These crossings at undesignated locations have twofold effects. First, pedestrians put themselves at risk, and, second, traffic speed and capacity are adversely affected. At unprotected mid-block locations, some of the vehicles may yield to pedestrians who are already at crosswalk location. However, some of the pedestrians are using forced gaps to cross the road. Hence, while pedestrians use the mid-block crosswalk with forced gaps, which decreases the vehicular flow characteristics. The pedestrian sidewalks do not show a direct effect on the vehicular flow characteristics when the pedestrian has pleasant walking facilities. The present study has analyzed the effect of the pedestrian crossing on the characteristics of vehicular flow at the mid-block location under mixed traffic conditions.

Due to lack of pedestrian walking and crossing facilities pedestrian mostly used regular traffic lane. Continuously increase in motor vehicles increases chances of collision with pedestrians. In such scenario, pedestrian safety is an important issue in most of the developing countries. In developing countries like India. Pedestrian behaviour is prime important in order to provide better safety to the most vulnerable road users and to arrest illegal crossing of pedestrians and reduce crash at such location in urban area. User's perception is very much powerful tool to carry out such behavioural study. The present study has been carried out with the objectives to analysed pedestrian safety at undesignated midblock section using user's perception. Pedestrian's perception information will be collected different high-density urban area with help of Questionnaire form survey. Collected Pedestrian different characteristics data such as Socio-economical characteristics data, Crossing characteristic data, Behaviour characteristic data, Traffic Characteristics data. Also ask to pedestrian regarding safety and risk. To collected pedestrian perception behaviour information through Questionnaire survey. Analysed pedestrian safety at undesignated midblock section at five scale rating. Survey is conducted at Ahmedabad; India and 78 sample of questionnaire survey is collected. Analysis of data was further analysed to assess safety perspective of pedestrian. Based on analysis results people having habits to cross at undesignated midblock section. Education and purpose not affected the safety.

With the help of development of technology, a growing number of traffic flow detection and analyses have been conducted by using video data. Time to collision (TTC) and post-encroachment time (PET) are two major parameters used to indicate the severity and probability of a potential collision and to capture an imminent vehicular accident. However, micro level pedestrian-involved collisions are less studied because they are hard to observe or record. This paper review various techniques which are used for safety assessment of pedestrians and study of interaction between vehicles and pedestrians. Time difference to collision (TDTC) parameter as a variation from TTC and PET is defined to fit the pedestrian-involved potential collisions/conflicts, analyze the interaction behavior between pedestrian and vehicles and assess the safety of pedestrians and vehicles at selected study locations.

Increasing in vehicular demands a large number of flyovers, moreover there is tremendous increase in the number of highways, in hilly areas. Here earth retaining structures are essential. For many years, retaining structures were made of reinforced concrete and were designed as gravity or cantilever walls which are essentially rigid structures and cannot accommodate significant differential settlements unless founded on deep foundations. For solving this problem Mechanically Stabilized Earth Technique is used. It is a construction technique with alternate layers of compacted soil and reinforcing elements to build retaining walls and embankments. The reinforcing elements, which can be either steel or synthetic, interact with the soil by friction and confinement and provide tensile capacity. The combination of soil and reinforcement behaves as a gravity mass that retains lateral earth pressures. The two materials produce a composite structural material that combines their best charact...

The recent development in the use of advanced composites in the improvement of soil is increasing on the basis of specific requirements and national needs. The need of efficient and strengthening techniques of existing soil has resulted in research and development of newer materials for improvement. Particularly for black cotton soil which have high swelling and shrinkage tendencies, demands great deal of attention for stabilization. Various techniques are available for stabilization of black cotton soil. Here as a further steps toward the innovative material to be used for stabilization, this study endeavor to use industrial waste material like Electric Arc Furnace Dust (EAFD) and dolime fine for the soil improvement. Steel industry plays an important role in the industrialization and development of a country, as it has the input within all manufacturing sectors. One of the most important problems encountered in steel foundries throughout the world is the management of the dusts pr...

Intelligent Transportation System includes a wide and growing suite of technologies and applications. Intelligent Transportation Systems deliver superior benefit-cost returns when compared to traditional investments in highway capacity. Intelligent Transportation System maximizes the capacity of infrastructure, reducing the need to build additional highway capacity.

Land cost in urban area is increasing day by day as a result of urbanisation, industrialisation and population explosion in developing countries like India so it became a challenging effort to put out a strong engineering solution for the sustainable structural stability at the costly places in the urban areas of covered land filling. Considering the vision of a sustainable development, the challenge of the geotechnical community is to supply more environmental friendly construction techniques, reduce the use of natural resources and promote the use of less harmful products. Solid waste disposal in landfills is the most economical form of disposal of waste particularly in the developing country as compared to incineration. Landfill Engineering Design Problems involve various aspects like determination of geotechnical properties of waste, land fill settlement, slope stability, field performance of landfill cover and liner systems, seismic behavior of the disposal site during earth qu...
