WIN (Web Information Network) Replacement project

a java web application used to record and analyse intelligence data about crimes received from British Transport Police, Bus garages and Schools. The original WIN application was developed seven years ago by a third party company who held the intellectual property rights, so TfL decided it was more cost effective to rewrite the application in-house to incorporate new customer requirements. My duties involved:

 

  • Design and development of a new data input facility for recording intelligence data via an input form spread over multiple tabs. Attended various user workshops to detain look and feel and layout.
  • Technologies used: Java 6, JSPs/Serlvets, Spring 3.*, Spring MVC, Spring Webflow, JSPTabControl Library, DWR Ajax, JQuery, Hibernate, PL/SQL, Oracle 10g
  • Unit testing with JUnit/Mockitos
  • Build with Ant, and deploy to OC4J dev and test environments
London Works Portal

A suite of Applications for the Road Network Planning team to assist in the management and coordination of Street Works in London between boroughs and utility companies with works notifications sent in via Webservices. My duties involved:

  • Enhancements/maintenance of an existing suite of java web applications using Apache Wicket, Spring, Hibernate, TopLink, OpenLayers, Javascript, Java Webservices, SOAP UI, Oracle 10g Spatial;
  • development of a web service client (Elgin Webservice Client) to push and pull road works and events data from an external hosted web service provided by Elgin (a UK road management agency) using Java 1.6, Axis 2.*, hibernate, quartz scheduler library – This application helped to increase the frequency and ease of data transferred between TfL and Elgin, from the previous once a day CSV/ ftp solution;

Applications include: Central Register, Forward Planning, ETON Webservices, PACMAN, Transport Management and Notifications (TMAN), Public Register (http://public.londonworks.gov.uk), Elgin Webservice Client.

A map application to provide online information to Customer Service Agents about activities and events along certain bus routes in London. a Java web application that provides a geographical map view of a variety of TfL datasets such as street assets, bus routes and recent traffic incidents for Tfl Customer Service Agents.  My duties involved:

  • development of prototype of application using HTML, CSS, Javascript to present at Users workshop to show the intended look and feel of the application.
  • design and development of functional components as part of IAP, using Java 1.5, JSPs/Servlets, Hibernate, DWR Ajax, XSLT, XML, Javascript.
  • create PL/SQL stored procedures utilising predefined database views
  • creation of map symbology using Oracle MapBuilder, and Oracle Mapviewer.

This application helped to reduce the amount of time and effort TfL Customer Service Agents use to answer questions from members of the public by integrating data from 7 different sources into one user friendly application.

Transport Police Online Mapping Application (TPOMA)

a Java web application that displays the crime hotspots within London in a geographical map view use by the British Transport Police and Community Safety Enforcement team.   This application helps to better plan the best location for deploying Community Safety Officers on the streets of London each day.
