By coming of Kollam bypass. This place is one of the most accident using Echotechnic road system, we aimed at a more prone areas in the city. To reduce the traffic congestion at the environment friendly, safer pavement promoting safe passage region, a flyover connecting the bypass in the Mevaram- for vehicles. Echotechnic road system mainly includes changes Kavanad side of Kollam city is proposed. The flyover at the done in the pavements which can control air pollution, water region is introduced using echo-technic road system. Echo- logging on road surface and can increase the durability of the technic road system is mainly focused on move towards a green road as well as reduce fatal accidents on roads. For the control infrastructure. It is a concept of an integrated infrastructure of air pollution, we use TiO2 in the pavement which absorbs air based on the most innovative technologies adopted inorder to dust and lets the atmosphere clean. By the use of permeable control global air pollution due to traffic as well as water pavements, the water logging on road surface can be reduced logging on road surfaces. These technologies can hence promote thus prevent skidding of vehicles thereby reducing accidents. smooth transportation at the junction with reduced accident Due to the use of porous asphalt in the road section, water will rates. As for air quality treatment, the main solution is the not sustain in the surface of roads and thus durability of road treatment of pollutants as close to the sources as possible. surface can be assured. Therefore photo catalytic materials can be added to the surface of pavement and building material. The pollutants are 1.1 OBJECTIVES OF THE PROJECT neutralized by the action of light and then gets washed away by ➢ The overall objective of the flyover is to provide an rain.

For the successful completion of the project, we ➢ The public felt inconvenience to cross Kallumthazham have mainly conducted the site survey and feasibility study of junction.

For water controlling measurements, ➢ To minimise the global air pollution and disturbances pavements with filtering type nature is to be provided.

A Flyover is a bridge constructed along an intersecting highway ➢ Moreover time can be very much saved due to the over an at-grade intersection. Flyover is one of the methods for absence of traffic signal at the region. solving traffic problems at-grade junctions on a highway including capacity, congestion, long delay and queue length. The area of the proposed flyover is at Kallumthazham, which is 1.2 SCOPE OF THE PROJECT the intersecting point of two national highways NH66 bypass, Kollam and NH744 passing through the Kollam city, Kerala. The traffic volume of the region can be largely Many educational institutions, hospitals and other important controlled since there is no signal system in the region. institutions of the city are located near to this region, As a result, Delay at Kallumthazham intersection can be reduced high traffic density is likely to be occurred here especially due to the absence of signal system. intersection, time during the morning and evening peak hours. From the traffic management can be done very efficiently and there study conducted on the region, it was seen that the present will not be wastage of travel time. system to be installed by the bypass authority, i.e. the traffic Due to the presence of certain materials in the signaling will not work satisfactorily there. By the completion of pavement, air pollution can be controlled to a great Kollam bypass road, the situation is likely to get worse. extend JETIR1806181 Journal of Emerging Technologies and Innovative Research (JETIR) www.jetir.org 411 © 2018 JETIR June 2018, Volume 5, Issue 6 www.jetir.org (ISSN-2349-5162) Replacing the normal pavement with permeable or PASSENGERCARS, 378 1 378 538 1 538 porous concrete can absorb water from the road surface AUTORICKSHAW, and can let the top surface of the road clean and dry quickly.
