An Analysis of road safety effects of land use
(2014-08-06) Ravindralingam, K; Emmanuel, R
Road safety is a major part of the highway sector. Accident problems are very complex in nature as so many factors are involved in its occurrence. The purpose of this study is to find out the interrelationship between land uses and road accidents in the different kind of road sections and make awareness of knowledge to improve road safety activities. The study area of road sections were considered as highly developed (urban), moderately developed (suburban) and less developed (rural area) for this dissertation. Data about accident, traffic and field inspection data such as dimension of road section and building area for Floor Area Ratio were collected to study the road safety analysis in different types of land use of road sections. It was found that a significant amount of accidents occurred due to land use related accidents. The highest number of accidents occurred in urban road section due to access road influence. At the same time, accidents caused by on street parking and pedestrians are also considerably influenced in urban road section. However, the cause of land use related accidents is lower in rural road section than suburban road section. This clearly shows that road accidents depend on land use effects of road sections. Land use activities influence accidents. Accidents were prevalent where there were more activities in road sections. In this study analysis, most accidents occurred in urban road section where commercial activities were high. This study also reveals that more accidents occur where there are more road user activities which are influenced by the Floor Area Ratio of the road section. Therefore, Floor Area Ratio influences the road usage activities and the number of accidents.

Environmental aspects of drainage systems in road projects
Ravindralingam, K; Ratnayake, N
Drainage systems in Road projects should be given due consideration because it influences the environment. The purpose of this research project is to study road drainage systems, as to how these affect the environment and how environmental factors affect the road, and what type of recommendation could be considered for effective, efficient and best use of the system to use in the anticipated road projects. This study is mainly concerned with the surface drainage system of the road sector. The areas selected for this study are Hakmana Town Intersection in Matara district, 1.3 km Road section from Imbulgoda on Colombo -Kandy road and Kiribathgoda Town intersection on Colombo Kandy road. The data such as Flooding, health problems, Accidents, Condition & maintenance of road drainage systems were collected through questionnaires, levels of the road profile were taken through surveying and the maximum intensities of the rainfall were collected from the department of Meteorology. Design and statistical analyses were carried out using the data. According to analyses, it was found that maintenance work influenced the flood, health problems in these sites were caused only by mosquitoes breeding and mosquitoes breeding were occurred not only by the flooding but also by the disposal of solid waste. According to this research study, it was found that the flood was the main environmental issue of drainage systems in the road projects. This problem could be controlled by proper drainage design and construction and efficient maintenance activities of drainage systems.
