Introduction – Problem Identification

Manual Railway Ticket issuing process in Sri Lanka

Long queues at office hours

Difficulty in dealing with cash

Average time to purchase a ticket is relatively high


Characteristics of a good solutionShould minimize the usage of human

resources involved in issuing ticketsShould minimize the cash involvement in

purchasing a ticketShould minimize the time required to obtain

a Railway TicketShould be able to facilitate a large number of

subscribers


Why MobitikiFully Automated Ticket Issuing SystemPrepaid Service for purchasing Railway

tickets minimizes the cash involvementComputer Vision Based(Barcode)

Authentication for minimizing the delay involved in Login in to the System

Usage of a 2D2D barcode in Authentication for achieving a large subscriber base

Usage of widely used Mobile Phones for storing the Authentication Barcode


System OverviewMain Components

Mobitiki Web Portal Mobitiki Mobile Computer Vision based user

identification system Terminal Application for ticket Issuing Admin Module


Mobitiki Web PortalUsers registers for the service via the Web

Portal

Also they can recharge their accounts

Mobitiki MobileAfter the users register in the Web Portal

they can download the Authentication Barcode Via the Mobitiki Mobile J2Me Application by providing the login details

Computer Vision Based Authentication SystemThe downloaded Barcode in a Mobile phone

is used for user identificationSemacode Standard is selected since it is one

of the best 2D Barcode Generating Algorithms in terms of accuracy and Encoding/Decoding speed

This Barcode will be captured using a Web Cam installed in the Railway Stations

Practical DifficultiesEncoding/Decoding algorithms need high

processing powerVarying Light Conditions make the Image

capturing and decoding processes difficultRequirement to facilitate a wide range of

Mobile Phone display sizes Facilitating Normalization for Rotation of the

Semacode


Further ImprovementsImprove the Encoding and Decoding

algorithms for maximizing the speedSemacode Decoding Algorithm has to be

enhanced to work under different light conditions

Implementation of the Normalization for rotation in the Semacode Decoding algorithm

Implementation of Haar Training to facilitate rapid object detection


Further Improvements contd..Implementation of Multi Language Support in

every application since the system is used by local population

Provide an actual teller like interface for purchasing Railway tickets


ConclusionTraditional System is entirely manualMobitiki addresses this problem by trying to

automate the whole process of ticket issuingSince this is a pre paid system the time taken

to do an actual monetary transaction is savedIt is possible to have multiple ticketing

machines at one station, which will be more cost effective than having multiple ticketing counters

Further the usual username password authentication was replaced with a Semacode based authentication system which is much faster than typing the username and password


Conclusion contd…Although a smart card system is also

applicable in this scenario, considering the cost of a smart card system the Semacode system is highly cost effective

Finally major aims of new technology are improving people’s convenience, save time and money

The objective of us was to introduce a new concept to Sri Lanka which may make the train commuters’ life much easier
