Book Description
Improvements to highway safety have become a high priority for highway authorities due to increasing public awareness and concern of the high social and economic costs of accidents. However, satisfying this priority in an environment of limited budgets is difficult. It is therefore important to ensure that the funding available for highway safety improvements is efficiently utilized. In attempt to maximize the overall highway safety benefits, highway professionals usually invoke an optimization process. The objective of this thesis study is to develop a model for the selection of appropriate improvements on a set of black spots which will provide the maximum reduction in the expected number of accidents (total return), subject to the constraint that the amount of money needed for the implementation of these improvements does not exceed the available budget. For this purpose, a computer program, BSAP (Black Spot Analysis Program) is developed. BSAP is comprised of two separate, but integrated programs: the User Interface Program (UIP) and the Main Analysis Program (MAP). The MAP is coded in MATLAB and contains the optimization procedure itself and performs all the necessary calculations by using a Binary Integer Optimization model. The UIP, coded in VISUAL BASIC, was used for monitoring the menu for efficient data preparation and providing a user-friendly environment.

Book Description
"The Highway Safety Manual (HSM) is a resource that provides safety knowledge and tools in a useful form to facilitate improved decision making based on safety performance. The focus of the HSM is to provide quantitative information for decision making. The HSM assembles currently available information and methodologies on measuring, estimating and evaluating roadways in terms of crash frequency (number of crashes per year) and crash severity (level of injuries due to crashes). The HSM presents tools and methodologies for consideration of 'safety' across the range of highway activities: planning, programming, project development, construction, operations, and maintenance. The purpose of this is to convey present knowledge regarding highway safety information for use by a broad array of transportation professionals"--p. xxiii, vol. 1.

Book Description
TRB's National Cooperative Highway Research Program (NCHRP) Synthesis 335: Pavement Management Applications Using Geographic Information Systems examines the state of the practice and knowledge of pavement management systems (PMS) using geographic information systems (GIS) and other spatial technologies, and discusses how the technologies have been combined to enhance the highway management process. The synthesis reviews the principal issues related to PMS data collection, integration, management, and dissemination; applications of spatial technologies for map generation and PMS spatial analysis; and implementation-related issues, including approaches used for integrating PMS and GIS and the different tools used to support pavement management decisions.
