GIS for Public Transportation Planning
The need for good public transportation services is quite certainly apparent, particularly for developed cities. Without it, everyone would either need to locate themselves close to place of work, or everyone has to use some alternative means of private transport. For large cities, where there are millions of people that need to travel on daily basis, it is simply not possible for all of this movement to function well without public transportation (Johnson 2004, p. 4). For a developed city to have good public transportation services, this does not happen by accident. City and town planners need the appropriate tools to conduct the work of creating appropriate plans for public transport, land use

For instance, a specific travel route can begin with walking to a bus stop, then taking a bus to a tram stop where a transit to a tram ride occurs. Subsequently tram travel is made to a location where subsequently walking is required to the final destination. With GIS applications, this type of routing analysis can be done fairly quickly and easily. Given a fair amount of assumptions, such as an average walk speed, it is possible to arrive at a fairly good estimate of travel time. The pedestrian road data informs the portion of the travel which is the walking parts of the route. The tram data informs the portion of the travel informs the portion of the travel which is that involving taking the tram. The GIS tool (for instance ArcGIS or QGIS) offers shortest route analysis functions that enable this type of route analysis to be completed. There are also network analysis functions in GIS applications that allow for service area analysis to be made. This enables the mapping of areas that are within a certain or distance of time of travel away from facilities or resources.
In order for GIS applications, to be effective, one has to bring data into the GIS application. And different GIS applications will have different capabilities for supporting importing or loading of geospatials datasets. A very common format for importing geospatial data is ESRI shapefiles. Yet another common

Certain analysis and functions will be more easily performed with one tool compared to another. Each tool will have various features, advantages and disadvantages. There is also the need for any user to become acquainted and familiar with the particular tool in order to be effective. There are also tools that are more "open" than others. Some tools require obtaining software and paying for it before one can use the tool. Thus, for certain situations this may present a barrier. There are also online GIS tools like CartoDB that can be quite effective for sharing map data and applications with other people. These tools do not have the same repertoire of analytical functions that a tool like ArcGIS would have, and so it is best to be aware of the capabilities of various tools so that one can employ the right tool for the
under funded public transit and urban sprawl contribute to the need to take on this burden?
These include encouraging commuters to use public transport, decongesting public transport, decentralizing businesses from the Greater Toronto Area, investing in transport infrastructure, passing relevant transport legislation and dialog with stakeholders in transport industry. These solutions aim at discouraging the use of private vehicles and increasing the effectiveness of public transport to increase the capacity and speeds needed to reduce congestion in Toronto. However, it is important to involve all relevant stakeholders when developing solutions to the transport congestion since as earlier discussed, these people may offer very effective solutions to this problem since they are the major road users. The general public will also be keen to follow changes made to improve the transport sector if it is involved in the change process. This will ensure that Toronto has one of the best transport systems not only in North America but across the
In this essay, I will discuss the topic of urban public transportation and how it relates to the Church and Wellesley BIA. The nature of transportation in Toronto is a highly complex topic. As discussed in the article Transportation: The Bottleneck of Regional Competitiveness in Toronto, there are many concerns with transportation in regards to international transport, roads, highways, rails, bike lanes, buses etc. (Keil, Roger, Young, 2008). These transportation variables all have a greater economic, health, and environmental impact. The article goes on to describe that mobility in Toronto suffers because its management is uncoordinated, and there is a gap in regional interaction (Keil, Roger, Young 2008). The scope of this essay will be to
Gilbert Castle has noted that real estate is essentially a game of information arbitrage. The likely winner of the game is the person that takes advantage of computerized analyses. Castle explains that GIS is an attention-getting way of showing what you know.(n1) Of course, larger data sets are used for GIS analysis, not just the minimum "three comps."
As applications of geospatial technologies continuously break the disciplinary barrier, the need for books on these technologies to reach diverse audiences is greater than ever. The challenge, however, is to write a book on this complicated subject that incorporates the knowledge of multiple disciplines and makes it valuable for those who may or may not have diverse educational backgrounds, but require using these technologies. Most books on geospatial technologies target a specific audience. Contrary to this, Geographical Information Science tries to target three different audiences (users, students, and engineers) by using formats and languages comfortable to them. While this effort is laudable, maintaining the balance and attractiveness to all the three audiences is challenging. The author, Narayan Panigrahi, has accomplished this balancing act but with mixed outcomes. His computer science background is clearly seen in the structure and contents of the chapters.
GIS is an emerging method of data storage and interpretation. GIS is, simply put a database. It is many tables of data organized by one common denominator, location. The data in a GIS system is organized spatially, or by its physical location on the base map. The information that is stored in the database is the location and attributes that exist in that base map, such as streets, highways, water lines, sewers, manholes, properties, and buildings, etc. each of these items don’t just exist in the database, the attributes associated with the item is also stored. A good example of this would be a specific sewer line, from and arbitrary point A to a point B. Ideally, the sewer line would be represented graphically, with a line connecting the two points or something of the like. When one retrieves the information for that line in particular, the attribute data would be shown. This data would include the size of pipe, the pipe material, the upper invert elevation, the downstream invert elevation, the date installed, and any problem history associated with that line. This is the very gist of what a GIS system is.
Public transportation is an essential part of a city. A good public transit can encourage a city’s economic activities and can provide its citizen a convenient life. Does our Phoenix public transit work well? Does it provide sufficient service to the citizen? From my experience, the answer is no. This November I tried to attend the popular State Fair in Phoenix. However, I found that there were not any buses or metros could take me to the fair directly. It means I need 2 hours or more spend on the public transits. As the sixth most populous city nationwide (“Phoenix Quick Fact” 1), compared with Los Angeles and other big cities in America, Phoenix’s public transportation is indeed subpar. Due to Los Angeles has 154 bus lines and 30 metros (“Schedule”), New York has 316 bus lines and 28 subways(“Maps & Timetables”), while Phoenix only has 98 bus lines, and the number of metro line is only one! (“Route Schedules & Maps”) The problem is
Longely et al (2005) state that there are many possible ways of defining spatial analysis but at the end all the definitions express the basic idea that information on locations is essential. Analysis carried out without knowledge of locations is not spatial analysis (Longely et al, 2005). Spatial data analysis (SDA) is a set of techniques created to support a spatial perspective on data (Goodchild et al, 1992). SDA can be differentiated from other forms of analysis by definition. It might be defined as a set of techniques whose results are dependent on the locations of the objects or events being analyzed, requiring access to both the locations and the attributes of objects (Goodchild, 1987; Goodchild et al, 1992). Spatial analysis is the heart of GIS because it includes all of the transformations, manipulations, and methods that can be applied to geographic data to add value to them. In a nutshell, spatial analysis is the process by which raw data is turned into useful information, in scientific discovery and decision making (Longely et al, 2005). A geographical information system (GIS) provides a powerful collection of tools for the management and visualization of spatial data. These tools are more influential when they are integrated with methods for spatial data analysis (Krivoruchko and Gotway, ). Bailey and Gatrell (1995) distinguish between spatial phenomena using the basic GIS operations such as spatial query, join, buffering, and layering and spatial data analysis as the application of statistical theory and techniques to the modeling of spatially referenced data, which is the discipline of spatial statistics. ArcGIS spatial analyst provides powerful spatial modeling and analysis features. GIS ...
Businesses that use GIS make faster and more cost-effective commercial decisions. Everything that is central to making the business a success can be analysed, managed and visualised using GIS. Osi.ie, 2017. What is a GIS? Geographic Information Systems (GIS) is a business information management system that helps us capture, analyse and present geographic information on a map.
This means that most ‘areas of interest’ (e.g. home, school and shops) are within walking distance of the station . For example in Hong Kong, the majority of MTR stations have a shopping mall, health care centre, and police station within five to ten minutes walking distance . If there are multiple TODs around the city, commuters can travel to and from TODs around the city via public transport with relative ease without having to change the mode of transport. This makes public transport more attractive since it could be even faster than using private automobiles, because railways can travel quickly without congestion as well as saving time to find a parking

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.
The geographic information is converted into linked geospatial data, for exposing, sharing and connecting resources in the web. For example, a geographical feature described in the data has a URI with links pointing to other geographical features based on their geospatial relation. The knowledge model and catalogue model of the datasets (metadata) is changed according to the developments in the field of semantic web to accommodate details that are necessary for pattern recognition and subsequent linking .The SDI should use open data...
Most of cities that people live are sequentially growing, daily routine of many people are also adapted for surrounding in the present. A lot of people have to spend most of their time with travelling though long distances to get from one place to another for connecting their businesses or other purposes by transportation. Most people use public transportation such as BTS and MRT to go each places while many people are using their own cars to travel. Thereby, both transportations have the same destination that is taking and moving people. People can choose vehicles from alter reasons depend on how people are responded to their needs by public transportation and private car that are different in convenience of travelling, expenditure of money and security of travel.
It is considered a holistic approach that might be involved some factors providing an overall speed of journey (Mannering, Walter, and Scott, 2004). Wyatt (1997) states that the rail transportation has been made the urban areas to develop the transport network places with producing a good network to be placed over location with a poor network. For example in European Union (EU), the rail company had been employing around 570,000 people across passenger and freight operations in year 2012. From here, the rail transport is critical by the EU strategy to improve their economic condition. This rail sector had been makes a large contribution in oversea country.
