What is GIS ?

A Geographic Information System (GIS) is a collection of computer software, hardware, data, and personnel used to store, manipulate, analyze, and present geographically referenced information.

Geographic Information systems (GIS) represent a powerful new means to efficiently manage and integrate the numerous types of information necessary for the planning, design, construction, analysis, operation, maintenance, and administration of transportation systems and facilities.

Introduction

Geographic information systems for transportation (GIS-T) can be defined as interconnected hardware, software, data, people, organizations, and institutional arrangements for collecting, storing, analyzing, and communicating particular types of information (i.e., transportation systems and geographic regions) about the Earth.

Role of GIS in Transportation

GIS TIS

GIS-T

GIS-T applications covered much of the broad scope of transportation, such as ◦ infrastructure planning, ◦ design and management, ◦ transportation safety analysis, ◦ travel demand analysis, ◦ traffic monitoring and control, ◦ public transit planning and operations, ◦ environmental impacts assessment, ◦ hazards mitigation, and ◦ intelligent transportation systems (ITS).

Applications of GIS

Transportation facilities, including roadways and railways, bridges and tunnels, air and sea ports, are planned and managed using GIS.

Public and private fleets are being made more efficient and effective through the application of GIS.

Both passengers and freight shipments arrive on schedule and more safely, due to the growing number of GIS-based information systems.

Applications of GIS-T are highly appreciated in major fields like: ◦ Aviation ◦ Fleet Management and Logistics ◦ Highways and Streets ◦ Mass Transit ◦ Railroads

• To develop transportation information system by using GIS.

• To generate error free digital data for further analysis.• To provide alternative measurement.• To solve various problems related to traffic system.

Objectives

Study area

Location of study areaHyderabad city and surrounding areas of Telangana state.

Geographically selected area covers in between lat/long : 17 6’ 28.7”N 78 7’25.05”E and 17 42’32.55”N 78 42’0.96”E.

Total area covered is 4067.3 sq.km Number of Roads considered in area are 28. The following are the types of roads captured in our

study area National high ways, Outer ring road, City roads, Bypass roads etc.

Google Earth along with Satellite Image Global Mapper GIS software

Data sets / software's used

Selected Study area on Google earth based on location

Captured area boundary from the satellite image based on major road network

All the Roads are captured by using Google earth satellite image and exported as kmz/kml file.

Exported data is geo-processed data

Google Earth 7.1.5.1557

Global Mapper is a tool where we can import the kmz/kml files, edit the features, add the field data (attribute information) to the captured features.

All the Routes are edited and separated as individual routes and exported as shape file (GIS format) for further analysis

Global Mapper v11.01

Used ArcView V3.1 for further integration Updated all other ancillary data by means of attribute

data in the tabular form. Routes are categorized based on specifications Identified various zones for further development Prepared final Map Layout

GIS software

In the above map , the routes are divided in to 6 categories

they are as fallows: 1-ORR Outer ring road 2-National high ways 3-Neckless road 4-Airport road 5-City road 6-Bipass road

Final report

The road suffers from various problems like

bottleneck traffic on-street parking improper placement of bus-stops, poor drainage and pavement damages

Problems in study area

High traffic congestion levels during peak hours near balanager, paradise and tank bund.

Due to the less width of roads at the junctions traffic intensity is more.

Improper maintenance of roads near kompally, bowenpally, koti.

Construction of metro: Construction works and equipment occupy a large amount of space and has also led to dusty roads which may prove hazardous to pedestrians, this type of problem mostly occur at miyapur and tolichowk.

The following are the major problems that are identified in our study area

On-street parking: Due to location of many shopping and office areas on the main road, users park their vehicles outside the buildings on the road.

Bottlenecks in traffic occur due to the uneven geometry of the roads and vehicles stopping near shops; the traffic does not move uniformly.

Heavy crowded area like secunderabad and near koti interrupt the flow of traffic and also cause accidents.

Finally these leads to environmental pollution.

Suggesting alternative routes.

Increase the width of roads at heavy crowded areas.

Proper maintenance of roads.

During peak hours ,we can provide alternative routes or allow the traffic into the less traffic lanes.

Flyovers at the junctions.

Solutions

Route Network of the Study Area

By using GIS we have developed transportation information system to solve various traffic related problems.

The error free data obtained can also be used for further analysis.

Suggested alternative routes for different factors, such as

1.Less distance 2.Best type of road
