The standardization of controller hardware under the Advanced Transportation Controller standard provided the flexibility for customized development of controller software. However, a multitude of controller software features on the market presents a challenge for the assessment when purchasing future system. This paper presents a decision-support application based on Analytic Hierarchy Process technique for the assessment of traffic signal controllers. The method to evaluate the controllers is based on the set of criteria derived from market controller features. The application consists of knowledge, model, data, and dialog management components. It was developed in MS Excel, along with supporting MS Access database. The application is highly dependent on the expert knowledge acquisition. It provides weighted Performance Index along with the decision-support visualization aids. The application was developed using previous research originally developed for a signal system under the purview of Virginia Department of Transportation (VDOT). However, the framework and application are transferable among agencies, and can be potentially used for evaluation of other signal infrastructure.
