A large number of road accidents and major road fatalities occur in Singapore each year. To lessen the same scenerio the factors must be clearly identified. Proper relationship must need to derive to know the magnitude of each factor in occurring road accidents. Both qualitative and quantitative factors have influence in occurring road accidents and road fatalities. The qualitative factors include the lack of traffic education and enforcement, drink-driving, speeding, red-running, hand phone driving, lack of training for motorcyclists, lack of campaign and so on. Though a big portion of road accidents are being occurred by the qualitative factors, it is very difficult to quantify them all with some numeric value. But there are still big portions of road accidents are being occurred each year by some quantitative factors. So, the existing study is designed only to distinguish the influential behavior of some quantitative parameters. It is assumed that the quantitative factors may have some influence on road accidents and road fatalities. So, some selected quantitative parameters will be examined by all possible regressions approach to investigate for linear relationships among them.

Bangladesh is a developing country with a per capita GDP of approximately US$500 per annum. The country¿s economy is mainly based on agriculture. However, this scenario has gradually been changing since 1990. A construction boom started in the country after 1990 owing to the necessity for industrial buildings, corporate offices, housing units, roads and other types of infrastructure. Bangladesh has made major progress in recent years, with sustained macroeconomic stability. The Government of Bangladesh has been pursuing a policy of promoting a competitive market-based economy through financial and industrial policy reforms, as well as trade liberalization.Major challenges faced by the Bangladesh construction sector in this context relate to how to improve the local technological capacity through technology transfer, enhance competition in the domestic market and improve the competitiveness of domestic enterprises through efficiency gains. In this book the key strengths, weaknesses, opportunities and threats for Bangladesh construction industry are identified. The business process for local and foreign firms are included with an emphasis on methods of tendering and taxation process.

Presently, Infrastructure management becomes the top priority of each government body to provide the best quality life to its citizens. However, due to lack of resources and rapid population growth, a big share of its citizens are deprived from their basic services. The most common services that are expected to provide from the government bodies includes education, utilities, recreational facilities, community services etc. Due to unplanned distribution of its resources, some regions are overly served whereas other regions have no accessibility to those services. Hence, it is utmost importance to formulate the policy to have equivalent access to each facility or service in terms of travel time or distance, travel cost, comfort etc. As a case study, Rajshahi City Corporation Area has been considered to analyze the performance of its public services using geospatial data and the policy and recommendations have been drawn.

A collocation meshless method is developed for the numerical solution of Partial Differential Equations (PDEs) on the scattered point distribution. The meshless shape functions are constructed on a group of selected nodes (stencil) arbitrarily distributed in a local support domain by means of a polynomial interpolation. This shape function formulation possesses the Kronecker delta function property, and hence many numerical treatments are as simple as those of the Finite Element Method (FEM). Nearest neighbor algorithm is used for the support domain nodes collection and a search algorithm based on the Gauss-Jordan pivot method is applied to select a suitable stencil for the construction of the shape functions and their derivatives. This search technique is subject to a monitoring procedure which selects appropriate stencil in order to keep the condition number of the resulting linear systems small. Various meshless collocation schemes for the solution of elliptic, parabolic and hyperbolic PDEs are investigated for the proposed method. Different types of PDEs are studied as test cases and all of the computational results are examined.
