Abstract: In recent time, traffic congestion problem has become one of the most costly, both monetary and environmentally, problems in many cities all over the world. It also causes valuable time loss of citizens. Many experts suggested that the foremost step to mitigate the congestion problem is to identify traffic congestion characteristics. This study has been conducted to measure the intensity of traffic congestion of Pabna town. Traffic volume survey and spot speed study were the main methodological approaches to conduct the study. The data collected has been analyzed through the use of different statistical computer packages. Different traffic flow theories and models have also been used to calculate traffic flow parameters that expose traffic characteristics. The study has explored that auto-rickshaw, cycle rickshaw, bicycle, and motorcycle are the popular traffic mode and traffic flow becomes so intensive during the morning, noon and evening hours. It has also revealed that Ataikula road is the most congestion-prone route than A.H road and the level of services of all intersections is F except traffic morr which provided a comparatively better level of services to the travelers of the town. The study has also identified the major problems associated with different road sections having poor level of services.

Abstract: Wireless sensor network refers to a group of spatially dispersed and dedicated sensors for monitoring and recording the physical conditions of the environment and organizing the collected data at a central location. The current abnormal wireless sensor network vehicle load data recognition method is more complex, which leads to low recognition rate, false alarm rate and slow recognition speed. Based on the genetic algorithm, the accurate method for abnormal wireless sensor network vehicle load data recognition is proposed. The effective feature set of abnormal vehicle load data in the wireless sensor network is constructed, to remove irrelevant features and redundant features from existing abnormal wireless sensor network vehicle load data. The abnormal wireless sensor network vehicle load data in the effective feature set are coded, to reduce the recognition time of abnormal wireless sensor network vehicle load data. The adaptive fitness function, crossover operator and mutation operator are applied to genetic algorithm, which can improve the recognition rate, reduce the false alarm rate, and realize the recognition of abnormal vehicle load data wireless sensor network. The experimental results show that the recognition rate of this method is high, the false alarm rate is low, and the time of recognition is less.

Abstract: Substantial parts of land mass of Bangladesh is built up gradually over ages by the process of deposition of silts carried by waters of three mighty river systems flowing to the sea. The process itself, i.e. deposition of silt, is likely to fill out the formed canals and rivers one day in the long future if it is not intervened. Ecology, however, livelihood including that of human, and environment have developed depending on waters and the river systems which existed so far. There has not been any human intervention, such as, by dredging but in recent decades Farakka has been erected. In up country, India, waters are being drawn out of flowing feeding rivers resulting in nearly no flow of water in the dry season. Thus Bangladesh may have only dried out rivers. The ecology and environment are thus threatened. Both the government and the people are concerned of the crisis and keen to find a solution for their existence. The present Prime Minister utters a slogan “save the rivers, save the country”. The envisaged solution is dredging and excavating rivers to increase their water holding and water flowing capacity. Two organizations which are entrusted by the government with responsibilities of water management have been given required budget and these organizations have been reasonably discharging their responsibilities. The paper outlines the concept of formation of land mass of Bangladesh, the gradually growing threat and cites undertaken steps and actions in reality towards achieving the solution. Restoration of river systems will improve, among others, environment, ecology, help recharging ground water, agriculture, fisheries, navigation and outflow of up country waters during heavy monsoon and floods. The paper may encourage others for development of waters and environment and attract international community to the efforts being made by Bangladesh.
