The paper outlines the use of GIS in road transportation including how the system has evolved over time in the transportation sector. GIS applications require specialized expertise to ensure an accurate collection, analysis, and relay of road network data. It is important to note that GIS systems can be applied in a variety of places within the road network. However, only three places are discussed in the paper: traffic density, vehicle emissions, and road capacity. GIS technology helps in the collection and dispersion of the necessary traffic information to optimize road usage.
GIS is regarded as an advanced technology that integrates other kinds of know-how using geographical data or information. The concept is a very powerful and effective technology, as it allows geographers to utilize their data and techniques in a way that merges traditional methods, including map overlay analysis, with more advanced modern methods to produce improved systems (Mavoa, Witten, McCranor & O’Sullivanc 2012, p. 17). Through GIS, geographers and engineers can effectively model, map, query, and evaluate large quantities of information kept in a single database. GIS is gaining popularity in road transportation where it provides effective and valuable expertise and equipment for managing vehicles during traffic. The technology provides a means for managing road transport by way of spatial reference systems, especially where roads form a convoluted transportation network (Razzak, Khan & Jalal 2011, p. 641).
Traffic density is one of the areas in road transport where GIS technology is applied; the know-how allows highway authorities and other concerned establishments to monitor traffic at critical points along the road network through the use of camera...

An effort to combat the continual development of urban sprawl, smart growth development looks to solve this dilemma. The idea of smart growth concentrates its development around compact walkable centers within urban areas. The purpose of this is to avoid the growing sprawl through the implementation of walkable, bicycle-friendly and alternative transportation like b...
...l estate industry. From the decision to lend money for the construction of a new skyscraper in Chicago, to the choice between the corners of a highway intersection for a new gas station, GIS plays a crucial role in allowing the key participants to make more informed decisions. Judging from the incorporation of GIS applications by today’s real estate companies, the importance of this tool will only continue to expand.
...regarded GPS – an indispensable part of GIS. Discussions on cartographic principles, commercial GIS software programs, satellite images, aerial photos, and geodatabases are some of the other conspicuous omissions in this book. There is an inconsistency in the depth of topics explored; for example map projections are explored in great depth, while vector topology is merely glossed over. These omissions and inconsistencies would in my opinion make this book marginally less beneficial to all the three audiences together. However, there is something for all them; structure for engineers, equations for engineers and students, and GIS concepts for students, engineers and users. This book will therefore be undeniably valuable if used to complement the material in some of the other fundamental GIS books in the discipline. It has merits, but there is room for improvement.
Building a GIS system from the ground up is a very time consuming and extremely expensive venture. This is why only large metropolitan areas have developed or are developing GIS systems.
Geographers plan new communities, decide where new highways should be placed, and establish evacuation plans. Computerized mapping and data analysis is known as Geographic Information Systems (GIS), a new frontier in geography. Spatial data is gathered on a variety of subjects and input onto a computer. GIS users can create an infinite number of maps by requesting portions of the data to plot.
Indeed, many global cities face compelling urban planning issues like urban sprawl, population, low density development, overuse of non-renewable natural recourses, social inequities and environmental degradation. These issues affect the cities themselves, the adjacent regions and often even globally. The resulting ecological footprint upsets the balance in adjacent rural and natural areas. Unplanned or organic development leads to urban sprawl, traffic problems, pollution and slums (as evident in the case of Mumbai city). Such unplanned development causes solid waste management and water supply to fall inadequate. Urban sprawl gives rise to low density development and car dependent communities, consequently leading to increased urban flooding, low energy efficiency, longer travel time and destruction of croplands, forests and open spaces for development.
Traffic engineers and planners need information about traffic. They need information to design and manage road and traffic system. They use the information for planning and designing traffic facilities, selecting geometric standards, economic analysis and determination of priorities. They use this to justify warrant of traffic control devices such as signs, traffic signals, pavement markings, school and pedestrian crossings. The also use this information to study the effectiveness of introduced schemes, diagnosing given situations and finding appropriate solutions, forecasting the effects of projected strategies, calibrating and validating traffic models.

Traffic jam is one of the most serious problems of urbanization, almost all the modern cities are facing different levels of traffic jam problems. In general, people can ease the traffic jam and not compromise the quality of life by a policy of sustainable development in two aspects including formulating a more efficient transport pattern and changing the urban construction.
Never the less these problems have arisen and present a very serious issue for not only our generation but for future generations also. Therefore, changes need to be made in Urban transport.
We all use vehicles for transportation. People usually go to their desired destination either by driving their own cars or traveling in public transportation. Actually, it might be tough to choose that which one is the best selection for people to travel. Many people choose one of them according to their comfort while traveling and both of them have advantages and disadvantages in different conditions. Public transportation and driving own car both shares differences and similarities in many aspects, such as facility, cost, and comfort as well as traffic jam and accident occurrence.

The development of every nation hinges on the effectiveness of their transportation systems. Movement of goods, services and people to and from locations is made possible by transportation systems. The importance of effective transportation systems cannot be over-emphasized. Many countries face transportation problems and my country Ghana is no exception. A trip of about 30 minutes usually takes about an hour or more due to traffic jams. This is seriously impacting productivity and has become a topical issue in the country. The situation is the same in Uganda where I currently work. To this end, Transportation Engineers are needed to design roads/ highways that will stand the test of time, plan effective traffic management systems to reduce
