INTRODUCTION

Geographic Information System (GIS) is acomputer based information system used

to digitally represent and analyse thegeographic features present on the Earth'surface and the events that taking placeon it.

GIS WORK FLOW

Data Collection:To build anyGIS, we need data. The datais collected, converted to aconvenient format and storedfor use in subsequentprocesses.

Display and Analysis:Thestored data is displayed andanalysed as per requirement.The data is displayed on acomputer screen and theoperator gives commands toperform analysis.Sharing:The result of analysisneeds to be shared with thedecision maker for furtheraction.

GIS IN HIGHWAY

Integrates your existingsystems and Data with

GIS, eg integrating CADdata by bringing it intoGIS and integrating as-built surveys and blue-

line drawings into anenvironment where theymaintain their correctspatial characteristics.

INTEGRATION Planning: Identify deficiencies and determine

optimal solutions.

Design: Integrate GIS with most design tools,including CAD, bringing greater analytic and

cost-estimation capabilities to your infrastructure

design process.

Survey: Manage and store GPS data and surveymeasurements more effectively.

Construction: Integrate project and financial

management software with GIS to better

manage infrastructure projects. GIS can provide

a single point of entry for all construction-related

documents and files.

Operations: Incorporate GIS into business

processes to improve your operationalperformance.

Maintenance: Easily manage disparate assets.Integrate your asset inventory with inspection

history and work order management to maintain

your critical investments in a cost-effective

manner.


11/32

OTHER FUNCTIONS Highway asset management:

integrates asset mapping withproject management andbudgeting tools.

Maintenance and Work OrderManagement: Tracking of worktasks, personnel, equipment anmaterial usage

Traffic Operations: viewing acomprehensive picture ofcurrent traffic conditions

Transportation Planning:

Analytical and visual tools tofind balance betweendemand on publicinfrastructure andenvironmental sustainability.

Asset Inventory Management

ArcGIS gives transportation planners powerful tools for

analysis and display that integrate with many travel-demand forecasting models.


12/32

Construction Management:integrated with projectmanagement and financialsoftware, to track performance,

organises survey data, soils,geotechnical studies to planning,environmental studies, engineeringdrawings and project maps.

Transportation Safety Analysis:better visualise and understandlocations with high numbers ofaccidents and their causes

Environmental Management: Helpsidentify wetlands, drainage areas,and sensitive habitats as well as

evaluate and manage the effectsof storm water runoff on waterquality. Integrates environmentalfactors with land-use andhousing and employment densityanalysis to help communities

address growth issues.

CASE STUDY

Transport and urban form in thirty-two

of the world's principal cities

By PETER W. G. NEWMAN & JEFFREY R.

KENWORTHY


14/32

The major purpose of the study was to establish

policies at the urban level for reducing transportenergy use

Other questions assessed by the paper-

How much variation is there in the transport and

land use of the world's major cities? How closely does transport relate to land use in

these cities?

How does automobile usage relate to theprovision of infrastructure for automobiles?

Are economic factors such as income and petrolprice dominant in determining transport patterns?

What are the direct policy implications from thestudy?

Research paper on

Transportation system management for Maduraicity using GIS

(map India conference 2009 by,dr. S, moses )


28/32

Transportation system management for Madurai cityusing GIS

This study suggest that how we can makegood infrastructure in highly congested areausing GIS.

Following areas were studied with the use ofGIS

Effects of one way streets

Diversion of traffic

Parking management

Effect of ring roads Overall improvement


29/32

So to solve this problem they find thatsome of that streets has to be madeas one-way streets, with the help ofthe parallel streets

(Map before and after the introduction of one way street in Madurai)

ENTERING THIS DATA THEY FIND THE SOME STREETS WEREHIGHLY CONGESTED.


30/32

(Effect on V/C Ratio before and After Application )


31/32

Analysis shows that the overall V/C ratio is less than0.81 for the present condition. But for the year 2007the overall V/C ratio is greater than 1.15.

Hence the long-term measures such as widening of

roads and construction new roads may beimplemented to reduce the congestion in thefuture.
