While initially conceived as a simple instrument for enhancing instructional experience, computers are now have been used in all facets of student life.
Keywords - ADT estimation, regression analysis, neural networks, origin-destination data, generalized cost functionĬomputers have become a vital and irreplaceable part of college or university students lives. The paper presents a comparison of the pros and cons of each ADT estimation model and recommends the most appropriate model for different conditions. A generalized cost function, representing the travel time, distance, and toll cost, is used instead of travel distance which has resulted in an improved Network Connectivity Factor through the revised link node system. Therefore, the model is further developed, incorporating important class-B road links, AB road links, and expressways to the link node system. It was identified that at some locations the estimated ADT is distorted because of the presence of expressways and important class-B links which facilitate inter-district traffic. The second model considered is based on the travel time, and calibrated using the regression analysis method. The model parameters have calibrated through regression analysis. The first model considered has been developed based on the travel distance and incorporated six input variables. These models assume that the ADT at a specific location is contributed by local traffic, regional traffic, and inter-district traffic across the measurement location. This paper aims to make a comparison between three recently developed models to estimate the ADT at any location of the class-A road network in Sri Lanka. ADT estimation models have been developed using different methods such as regression analysis, and neural networks. In conceptual planning stage, it is sufficient to use estimated ADTs obtained from a model, which saves time and cost. Eventually, the most common techniques for predicting telecommunication churning such as classification, regression analysis, and clustering are included, thus presenting a roadmap for new researchers to build new churn management models.Īverage Daily Traffic (ADT) data are mostly used in transportation engineering for the purpose of planning and designing roads, pavement capacity designing, prioritizing road maintenance investments, accident studies, etc.
It epitomizes the present literature in the field of communications by highlighting the impact of service quality on customer satisfaction, detecting churners in the telecoms industry, in addition to the sample size used, the churn variables used and the results of various DM technologies. This paper supplies a review of nearly 73 recent journalistic articles starting in 2003 to introduce the different DM techniques used in many customerbased churning models. Researchers around the world have conducted important research to understand the uses of Data mining (DM) that can be used to predict customers' churn. These data can be helpfully extracted for analysis and used for predicting churners.

This satisfaction raises rivalry between firms to maintain the quality of their services and upgrade them. As well as better awareness of customer requirements and excellent quality that meets their satisfaction. The telecommunication sector has been developed rapidly and with large amounts of data obtained as a result of increasing in the number of subscribers, modern techniques, data-based applications, and services.
