Air Pollution Monitoring System based on Wireless Networks - Simulation

Air pollution is one of environmental issues that cannot be ignored. Industrial growth and urbanization results in the air pollutants concentrations in many areas. These pollutants can cause damages in human health and other living organisms. The available pollutant emission monitoring systems, such as Opsis, Codel, Urac and TAS-Air metrics are typically expensive. In addition, these systems have limitations to be installed on chimney due to their principle of operation. This causes other areas surrounding the factories being unmonitored and hence cause healthy issues. This paper proposes an industrial air pollution monitoring system based on the technology of wireless sensor networks (WSNs). This system is integrated with the global system for mobile communications (GSM) and its communication protocol used is zigbee. The system consists of sensor nodes, a control center and data base through which sensing data can be stored for history and future plans. The proposed system can be deployed to the industries for monitoring carbon monoxide (CO), sulfur dioxide (SO2) and dust concentration caused by industrial emissions due to process.   Keywords: Zigbee, wireless sensor network, air pollution, GSM, network topology

Implementation and Impact of ICT Technology on Vehicle Over-speed and Drinking Driving Monitoring in Tanzania: A Survey

Today’s transportation status has rapidly grown due to the daily increase of population and use of road as main, easy and economical way of travelling as well as transportation of goods, Thus now a days due to the high quantity of vehicles several problems has arisen in road sector such as road damage, road accidents, congestion as road accidents has been a major problem in Tanzania which in many cases results from the Breach of Traffic rules. Many innocents Tanzanians are continuously losing their lives and some get permanent body disabilities and property destruction due to road accidents. From 2009 to 2010 there was an increment of 2,907 accidents which is equivalent to 13.2% and most of the causes were due to human factors which include over-speed, drinking and driving, reckless driving, overtaking and overloading. Some of the measures have been taken but still there are many challenges. Traffic Police have been using devices (speed radar and breathlayzer) but have shown some weakness on solving problems. Information and Communication Technology (ICT) Also contributed a lot to control the problem as introduced many ways of automatic control. Thus this paper will review the system used for prevention/avoidance of drinking & driving and over-speeding in Tanzania. It will also propose a system that will monitor and provide real time information of drivers drinking & driving status and over-speeding in different zones of different speed limits.

Design of an Integrated Android Mobile Application and Web-Based System (IAMAWBS) as a Solution to Concerns of Passengers Using Bus Rapid Transit System for Public Transportation in Dar Es Salaam

This research article published by Modern Education and Computer Science Press, 2019The rapid population growth in Dar Es Salaam has prompted the demand of effective transport system in the city. This tremendous rise of population led to serious road traffic congestions, which brings a number of challenges into the city and other growing urban areas. City authorities attempted various solutions to control the traffic congestions such as construction of new roads, expansion of existing roads, installation of traffic lights and other transportation infrastructures such as reestablishment of commuter train to operate within the city but they couldn’t effectively relieve the problem. Eventually, the Government of Tanzania (GoT) supported the city’s effort by establishing the organ called Dar Es Salaam Rapid Transit (DART) to supervise the implementation and operation of Bus Rapid Transit (BRT) system. The BRT system provided direct benefits to passengers such as minimal travel time, improved reliability as compared to other public transport commonly known as daladala, and reduced accident as BRT buses travel in their dedicated lanes. Despite these benefits there still persist transportation challenges with the BRT, where passengers still suffer from waiting on very long queue during ticket booking, shortage of smart cards, they are unable to check balance direct from their mobile phones, as well as they fail to top-up onto their card’s balance using their smart phones. This paper presents a software technology approach that would help passengers to check balance, send request specifying station to board a bus and check the bus arrival time at any station
