Abstract— Roads are considered as the measure of the Infrastructure development of the country. Roadway construction planning involves dealing with a number of activities and information simultaneously. A large amount of information regarding design, construction methodology to be followed, quantities, unit costs & production rates, etc is to be continuously processed & refined. Doing this manually is time consuming & cumbersome as the size of the projects today has increased manifold. Geographic Information System (GIS) is a very effective tool for integrating & managing various types of information required for roadway construction planning. This piece of work tries to understand how GIS can be applied for improving roadway construction planning. It also aims at developing a system which can help construction planners to make a proper decision with features like space scheduling & activity sequence visualization process. Keywords— Aarey colony, Roadway Planning, GIS, Gram++, Visualization, Decision making

I. INTRODUCTION

Our Country is Developing Country. The Last two decades of Economic liberalization has resulted in an improved infrastructure and Standard of living. Still there is a lack of Infrastructure in India which is one of the primary requirements of our Country. The growing population of the world has resulted in huge industrialization & subsequent urbanization. This requires quick & efficient set up of urban infrastructure. Roads are called as the measure of the development of the country. This statement holds true only if the roads are properly planned & executed in time. Proper planning requires skilled workforce & technological advent. A large amount of information about construction methods becomes difficult to be sorted using traditional methods. Hence there is a need for an improved method of solving this problem as size of projects nowadays has increased. The better way to solve this can be with the help of GIS. Geographic Information System (GIS) can prove to be a very effective tool for integrating & managing various types of information required for roadway construction planning in a developing country like India, where continuous efforts are being made to improve road connectivity through nation.

III. STUDY AREA

A. Project Features: Name of Project: Infrastructure Development Of Aarey Milk Colony. Location: Goregaon East, Mumbai. Data Collected: Topographical Map of Aarey Milk Colony. Auto Cad Drawing Of Map Of Aarey Colony. Auto Cad Drawing Of Section of Road. Traffic Volume Data. Climate Zone.

Geometry Class. Details of Section on The Project Road. Existing Cross Section for Aarey Road. Future Cross Section for Aarey Road.

Length of Road: 7.5 Km

IV. METHODOLOGY. Software Review:

The software used for this Project is GRAM++ (Geo Referenced Area Management), developed by CSRE, IIT MUMBAI. MS-Access 2003 is used for handling database. The basic aim of this work is to develop a GIS – based system for improving roadway construction planning. The methodology that is adopted is described as under by Using Gram++: 1. A printout of CAD file is taken, scanned and saved as a bitmap image (scan.bmp) 2. Scan Map Open In Gram++

Fig:3 Scan Map Of Aarey Colony 3. With the help of Google earth, the point marks are fixed, co-ordinates for the same bitmap image

Fig 2 : AutoCAD Map of Aarey Colony



4. The entire map is Digitized and layers as per the requirement are formed in Map-Edit module of Gram ++ 5. Creation of database for various fields (In mdb.)

6. A default database is generated by the software. To this, we can add the desired fields and the values for the same by clicking on Add field to database and update/modify database icon.

Fig4: Add And Update Database

V. ANALYSIS AND RESULTS Running Queries Vector Analysis Queries in Gram++ : - Running queries to check the integration of the database with the digitized image. The algorithm for Running Simple Query in Vector Analysis is as under:

a) Open Gram++. b) Select the Vector Analysis module and open the .vec format file. c) Activate the layer for which database was created. d) Go to “Tools” menu in the top tool bar and select “Query” for the selected layer. e) A menu pops up containing three options as shown below. Select “Simple query” option. Click Ok. f) Select (double click) a field for which the query is to be run. g) The selected field will be shown in the “Enter Condition/Query” window. Enter the desired operators. Then

double click on the “Field Values” to select a value. This value will also be shown in the “Enter Condition/Query” window. Click Ok.

h) The results of the query will be shown highlighted on the layer for which query is run.



Fig 5: Running a query in Gram ++ (Source: Screenshot, licensed copy available with VJTI) Query 1 : Show sections where Excavation quantity > 1500 Cu.m

Fig6 : Results of the query run (Source: Screenshot ,licensed copy available with VJTI)

Utility: This query can help us identify the sections where the quantum of earthwork to be done is more(For e.g : 16 out of 26 sections in the above area have excavation quantity greater than 1500 cu.m). Accordingly, depending upon where the source or destinations are located, we can employ loading and transporting the equipments. It can also help us to balance the equipments required by designing their cycle times.

Query 2 : Show sections where Paver Block Area <1000 sq.m

Fig7 : Results of the query run (Source: Screenshot ,licensed copy available with VJTI) Utility : It helps to gauge the Paver Block Area for a particular segment (For e.g : 16 out of 26 sections in the above area have Paver Block Area less than 1000 sq.m). and estimate the shape , thickness and number of Paver Block required. It helps in carrying out the Cost Benefit Analysis considering a particular type of paver block and hence reduction in the time taken for the purchase of paver blocks. It helps in improving material handling and management .



Query 3 : Show sections where number of T-Junctions > 2 Numbers

Fig8 : Results of the query run (Source: Screenshot ,licensed copy available with VJTI)

Utility: This kind of a query can help us know the sections where T-junction is present (For e.g : 3 out of 26 sections in the above area have T-junctions greater than 2). It also helps us to identify locations for Speed breakers and signboards and estimate their numbers. Thus it helps in reduction in the time taken for their installation and make necessary arrangements for transport

Query 4: Show sections where % of completion of work > 35%

Fig9 : Results of the query run (Source: Screenshot ,licensed copy available with VJTI) Utility: Queries related to percentage work completion in a particular section can help us identify the sections which are either ahead or behind the schedule (For e.g : 17 out of 26 sections in the above area have work completion percentage greater than 35%). The reasons for delays if any can be known, examined actually on site and then necessary measures can be taken so that the schedule of the project as a whole remains undisturbed or is least affected. The onsite workforce can accelerate the work as per the instructions of the planning and scheduling team.



VI. CONCLUSION With the growth in population of the world and inclination of human race towards residence in urban areas, it has become the need of the hour to set up quick and efficient urban infrastructure. For this setup, roads are the prime requirement. This application which uses Gram++ as a platform is a user friendly tool for planners, executors as well as monitors. It can help to make intelligent decisions; check the feasibility of different alternatives available and select one out of it which comes out to be the most optimal. This study will benefit project managers, site engineers and clients in the following manner: Project Manager :

Cost incurred/Spent and the quantity of materials used on site can be known Allows for fast decision making process and smoother communication among other members/parties involved in

project. Site Engineer :

Helps in informing the contractors beforehand about the start of their work or lackings of any. Can maintain a good record of all activities and works for final billing purpose.

Client : Has a view of the progress of work thus knowing where large cost has been incurred Helps in presenting the Project Progress to Investors involved with the project.
