Development of content management system for traffic survey reports
(Department of Civil Engineering, University of Moratuwa., 2010) De Silva, SCP; Bandara, JMSJ; Pasindu, HR
Transportation has become one of the key development factors in Sri Lanka recently. More studies and research have been initiated relating to the transportation infrastructure development. The one of the essential parameter for these studies and research is the availability of traffic related information Since traffic data is vital for any type of study or research in transportation, the traffic survey reports files should be stored efficiently in a suitable repository from for interested party to view or use them. There are different types of surveys conducted to gather traffic related information. Efficient mechanism to store collected data and an easy access to past data is a growing requirement. Currently there are no proper ways of keeping all surveys results that have been conducted. This paper discusses the development of a content management system to handle traffic related information. A development of Content Management System for managing all common types of traffic and transport surveys is discussed. A separate file server is configured to store digital copies of survey results while end user software is connected with server and give all information about surveys. The Users can download relevant data from the server. java technology was used in developing the software and relational database management concept was used to develop the data model. The database schema is developed by identifying the basic information/data regarding to be stored from any survey type (O-D, MCC etc.) by applying the concept of relational database and EER modelling. The software development has gone through the basic steps defined in waterfall method. The final system is user friendly and safe since all the information is gathered to one central server database. Using this central server any type of survey reports can be retrieved with details. The administrator who is responsible for the system can grant the privileges to other low level users to do their tasks separately. Both functional and non functional requirements have been considered in the development of this database. As functional requirement the main processes for the system have been considered. For non functional requirement the quality of the system; security, reliability, performance, resources etc. have been considered based on the software and hardware components.

Traffic information system for Sri Lanka
(2014-08-18) De Silva, SCP; Karunadasa, PM
Transportation is one of the most development factors in Sri Lanka recently. Therefore it has also become the basic area for conducting research. Transportation Engineering Division at University of Moratuwa is such an institute in Sri Lanka that contribute in many research on Transportation. In addition they have the responsibility in taking decision and conclusion on planning of future development regarding to transportation in Sri Lanka. The one of the important factor for this type research is survey reports. The researchers sometimes need to conduct new surveys or they would need some passed survey reports to continue with their research. The Surveys are conducted at pre decided location that affect to the individual project or research. The mechanism that is used to collect traffic data at survey location is slightly different at many occasions .most of these differences are basically caused by "Vehicle Classifications", "data collecting time intervals " factors. This could affect to estimations of traffic counts, traffic forecasting and other relevant analytical calculations. There is no sudden way of getting analytical solution by accessing these survey reports. Though large number of traffic surveys is conducted every year but there is no mechanism to easily retrieve past data for any comparison, analysis or other estimation. Not having a proper indexing system or centralized data base is one of the reasons for the above and the other reason is the non uniformity of data collection at different locations. Sometimes The Research People needs to go through the survey reports or other specific documents regarding to particular survey, but no central location or sound file system to easily obtain them. Therefore many transport studies are conducted with minimal information due to lack of past information or spend lot of money and resources to collect information. The computerized system including file server and database server is proposed with the features of accessing these survey entries in estimation, planning and obtain analytical solution through the traffic data .All features are under privileged environment.
