Interactive Highway Safety Design Model (IHSDM) is a suite of software analysis and decision-support tools, widely used to check the design consistency in response to required safety and operational performance level along two-lane rural highways. It can only identify the inconsistent sections along a given highway. Therefore, after every check, the inconsistent sections are redesigned and checked again to ensure consistency. This process is manual and time consuming. The objective of this research is to incorporate the highway alignment design capability to the IHSDM. This will reduce the manual repetitive steps involved in the highway design and checking. In this study we have used highway geometric design properties and integrated it with IHSDM such that the inconsistent sections of the highway are replaced with sections having optimal safety and operational performance level. This method, first identifies the inconsistent sections from the given highway alignment using IHSDM and then replaces them with new, most appropriate sections. This process continues till all inconsistent sections are replaced. A real-world problem is solved in this paper using the proposed method.

“…The objective functions related to the users and operator of the road may usually be expressed in monetary terms, and the objectives related to the environment may be expressed by rather complex constraints in the problem. Hence, this optimization problem may be better approached by heuristic than conventional routines, as is correctly mentioned by Kim et al [1].…”

Road alignment design is an important determinant of the development cost of road networks.On the one side, it affects road construction and maintenance costs, which constitute a significant part of country-wide infrastructure development, management and operation budget each year.On the other side, it affects road user-related costs of travel time and vehicle use, which comprise a significant portion of the total transportation cost. This study adapts the existing Electromagnetism-like meta-heuristic algorithm to solve a three-dimensional highway alignment problem, which explores and finds a good route between two given points on a terrain. It detects the potentials of the given initial routes, which are enhanced and shaped toward better positions by the help of the local and global search. The final good solution is, then, fine-tuned for a better alignment. Several example problems are designed to show the behavior of the algorithm. The results show that the algorithm satisfactorily maneuvers to by-pass obstacles, and build highway structures where necessary. The set of the example problems in this paper may also serve to found a basis for evaluation of the performance of alternative algorithms.
