I believe that transportation engineering provides us with an excellent platform to study how technology, science, humanity and social sciences interact. Mobility is one of the essential requirements for human activity. The present state of our cities and our way of life depend very much on the way that transportation systems were developed over the years. The shape and functions of the city are also changing dynamically with the transportation systems. The study of transportation helps us understand the complex phenomena that underlies between mobility and socio-economic activities of the people.

Because the study of transportation deals with complex phenomena, organizing the cause-effect relationships systematically is essential. My approach to transportation is to develop a sound reasoning base for proposed solutions by learning from the past phenomena combined with the principles of economics, physics, mathematics, social sciences, and the culture of the region. The aspect of dealing with incomplete knowledge and incomplete data when making inferences is my current research interest. In many instances, the answer can lie between yes and no, and the unknown must be recognized. In other words, how to express what we know and what we do not know in an honest and forthright manner and to measure the strength of reasoning is my general theme of research in transportation.

Within this framework, I study the relationship between information and decision when planning urban transportation systems, Intelligent Transportation Systems, logistics, and development of transportation policies. My current research topics include understanding the data needs for planning and operations of public transportation, development of simulation models for traffic flow both for automobiles and human activities, and measuring the quality and value of information. Further, most recently I am interested in the idea of the agent based system, in which individual elements which comprises of a system has desires and “life” of its own. The elements may be different stakeholders and interest groups. Instead of the top-down optimization, using the bottom-up approach in which the individuals play to maximize its own utility, one might be able to see an organized pattern of the behavior of the entire system. The use of this concept has allowed me to formulate the traditional optimization topics of transportation in the multi-objective context by considering the desires of individual system elements, which may yet be not completely certain.

Traditionally in transportation engineering, uncertainty is addressed in the probabilistic framework. In the past two decades, a significant advance has been made to systematize the approaches to uncertainty in Systems Science. Under this larger framework, different theories have emerged to deal with different types of uncertainties. Since transportation deals not only with the statistical information but also with perception, desires, incomplete data, natural language, visual images, etc., and since the nature of propositions is not always well defined, the truth of a proposition needs to be analyzed carefully, consistent with the type of data and the type of proposition. One of the important challenges facing civil engineers today is accountability. I want to advocate proper treatment of uncertainty in a scientifically credible manner in the process of prediction, diagnosis, and control/regulation.
