...[pic] As far as memory goes, traffic congestion and pollution have become the major challenges to be overcome by local governments. Whilst some people think that these problems may be only solved through a fuel cost increase, the counterpart believes that more effective strategies should be taken instead. In this essay, it will be argued why the fuel cost increasing proposal is unfeasible as well as showing some more adequate solutions. To begin with, a possible approach by reducing the aforementioned issues would be by hitting fuel prices. However analyzing deeper, in the long run this fact might cause a large-scale public transport usage, so bus stations would be bound to suffer overcrowding. That is why transport systems should be improved across the implementation of new infrastructures such as underground trains, sky trains and so forth. As regards the contamination issue, this may be only tackled by way of the alternative fuel usage, which will help us struggle for the environment protection that has been coming under threat during the last years. Thereby, governments should foster people to purchase cleaner alternative fuel working vehicles such as ethanol, natural gas and biodiesel. Having looked at both sides of this argument, it is undeniable that the combustible price modification would not have any influence in the aim to achieve. Supporting this belief, the most densely-populated cities have adopted the previously mentioned measures showing successful...

...International Journal of Computer Applications (0975 – 8887) Volume 83 – No 9, December 2013 Real Time Traffic Density Count using Image Processing Naeem Abbas Muhammad Tayyab M.Tahir Qadri Sir Syed University of Engg & Technology University Road Karachi-75300, Pakistan Sir Syed University of Engg & Technology University Road Karachi-75300, Pakistan Sir Syed University of Engg & Technology University Road Karachi-75300, Pakistan ABSTRACT Due to the increase in the number of vehicles day by day, traffic congestions and traffic jams are very common. One method to overcome the traffic problem is to develop an intelligent traffic control system which is based on the measurement of traffic density on the road using real time video and image processing techniques. The theme is to control the traffic by determining the traffic density on each side of the road and control the traffic signal intelligently by using the density information. This paper presents the algorithm to determine the number of vehicles on the road. The density counting algorithm works by comparing the real time frame of live video by the reference image and by searching vehicles only in the region of interest (i.e., road area). The computed vehicle density can be compared with other direction of the traffic in order to control the traffic signal smartly. Keywords Traffic density count, image processing, intelligent controlling of traffic. 1. INTRODUCTION The...

...changing needs and advanced technology humans are able to create variety of innovative products. Simon Hobday, energy partner at Osborne Clarke writes this article about driverless cars. The good news for the governments and manufacturers backing a driverless car revolution, however, is that 46% of us would appear to have no qualms about being driven around by a computer. With testing due to start this year in Bristol, Coventry, Greenwich and Milton Keynes, it’s now vital for the UK government to win over opponents and “don’t knows” alike. These cars are intelligent transport mix is important element of a smart city and that is what the government is aiming to build. These cars will be able to access targeted, fast and efficient transport systems as well as will have the biggest impact on the wellbeing of the citizens and economic growth. One of the major effects of driverless cars is that a reduction will be seen in car ownership. Mostly cars will be used for specific journey types and shall be hired for short periods. Another change would be fuel consumption will be reduced along with carbon and particular emissions. The other benefits include increasing mobility and safety of the elders, blind and disabled. There’s also the potential for stress reduction and the eradication of road rage. Driverless cars could be a huge force for good, but buying into the concept is a huge leap for many. However, an investment in helping people understand the benefits now will pay major dividends...

...Intelligent Traffic Control and Pedestrian Crossing System C.H.W. Jayawardane Faculty of Information Technology, University of Moratuwa, Sri Lanka Abstract - This paper proposes an intelligent traffic light and pedestrian crossing system that can be used to address traffic congestion in a four way junction. The approach is primarily focused on creating a system which dynamically responds to traffic conditions and road users. The system makes use of sensors to detect the presence of a vehicle. A number of these sensors placed accordingly are used to identify the number of vehicles in a particular lane. Based on this input, which is the vehicle line length in a lane the traffic control algorithm implemented in our system takes the necessary decisions. This algorithm determines the lane that should be given the most priority and up to what amount of time. This feature allows maximum efficiency in controlling the flow of traffic. The pedestrian crossing system uses image processing technology to identify the number of waiting pedestrians. When this number reaches a defined value they are given the chance to cross the road. Else after a maximum time limit is exceeded and the required number has not yet gathered the remaining will be given a chance to navigate safely across the road. A count down timer display is used to show the remaining time the pedestrians have. It can be illustrated that the proposed system provides a cost efficient and environmentally friendly method to all...

...TRAFFIC SIGNAL SYSTEMS 1 Combating Congestion Utilizing Adaptive Traffic Signal Systems Gregory Blazina University of St Francis MBAD 656 – Transportation Management & Economics Donald Maier PH.D. August 10, 2007 TRAFFIC SIGNAL SYSTEMS 2 Abstract Traffic congestion is an inescapable problem in large and growing metropolitan areas across the country. With 88% of America’s daily commuters using private vehicles, eliminating traffic congestion is practically impossible. The challenge then becomes finding the best methods to manage congestion as to minimize its impact on commuters, the environment, and the economy. The field of transportation engineering continues to grow and expand with an increasing use of advanced technologies to reduce congestion within our nation’s roadways. One set of technologies, which has evolved over the past 30 years and shows excellent potential for improving traffic conditions in urban areas is advanced traffic signal systems. These systems are the focus of this paper. TRAFFIC SIGNAL SYSTEMS 3 Congestion has traditionally been labeled as a problem to be solved. Between 1980 and 1999, vehicle miles of travel on U.S. roadways grew by 76 percent, while lane miles increased by only 3 percent. Average daily vehicle volumes in urban areas rose by 43...

...According to a McKinsey Global Institute study, “, China will have an urbanized population over one billion by the year 2030, from approximately 600 million today. As 400 million more people move from the countryside to urban population centers, there will be massive shifts in income, consumption, and the use of public goods (mass transportation, education, etc.). These changes will have a great impact on China’s society and economy. Why China’s Urbanization cannot be stopped China’s development over the last 30 years since the opening of China’s doors in 1978 has been anything but a smooth, national process. Indeed, starting with Guangzhou and following with Shanghai, Beijing and now Tianjin, the mega-cities have developed at a much faster pace than its surrounding areas, with surrounding cities, and rural areas lagging far behind. Both geography and socio-political concerns have contributed to this pattern of growth. Geographically, the coastal areas have been China’s traditional powerhouses in trade and commerce, and given China’s borders with the Himalayas, the Gobi Desert, and the tropical forests of Southeast Asia, the coastal areas served as China’s primary (if not only) conduit to the West. Socio-politically, Guangzhou’s and Shenzhen’s proximity to Hong Kong made them ideally suited to serve as the first door to the west; Shanghai’s location at the terminus of the Chang Jiang made it a historically important port of trade, both for domestic trade inland and for ocean going...

...China 2015: Transportation and Logistics Strategies Leadership requires innovation, expansion and redesigned networks A s China’s economy grows, so grows its transportation and logistics industry. China is becoming a more mature and self-confident country and a driving force in the new global economic structure, and this is bringing new challenges and opportunities to the five sectors of the country’s transportation and logistics industry — express, road freight, air freight, contract logistics and international freight forwarding. How can Chinese companies improve the country’s transportation and logistics environment? Leadership in this industry requires innovation, expansion and redesigned networks. China’s extraordinary economic growth continues. Even as the global economy struggles to recover from the financial crisis, various statistics indicate that China’s economy has emerged resilient, with rapid growth expected to last into the foreseeable future. In this context, the transportation and logistics industry in China is also poised for major growth over the next five years, portending significant changes for its five main segments: express, road freight, air freight, contract logistics and international freight forwarding (see figure 1 on page 2). As the boundaries between these segments blur, consolidation will accelerate and network coverage and density will grow. At the same time, an increasing focus on sustainability will add new pressures to cost structures....

...mainland China efficient? The distribution, transportation and logistics area of China is considered to be extremely intricate and complex as well as being very competitive. Companies far and wide continue to fight for a share within China as their market rapidly grows from time to time. Their economic growth has seen to have increased in the past years positioning them second to the United States. China’s current physical infrastructure has also been developing quickly over time although executives have realised that operational and regulatory processes have often hindered efficiency. This determines the fact that the logistics systems need to be enhanced and improved immensely therefore the distribution of products and services should be advocated by a reliable transportation system. However, China’s current logistics system has been met with many challenges making it exceedingly difficult. The existing infrastructure has aged over the years making it highly unlikely to meet certain demands, coupled with the lack of personnel and handling equipment. This automatically leads to higher logistics cost. Dekker, N. (2002) states that the proportion of logistics cost to total production cost is estimated at 20-30 per cent in China, compared to only 10 per cent in the developed countries. According to Speece and Kawahara (1995), Chinas railways and shipping were considered insufficient to meet certain standards in 1990. As a form of transportation for goods to be delivered to different...
