Product Description

TRADAS (TRAffic DAta System)

TRADAS (TRAffic DAta System) is a software system for collecting, editing, summarizing, and reporting a wide range of traffic data. TRADAS 2006, written in Microsoft Visual C++®, Microsoft Visual Basic 6® and Visual Basic .NET 2005®, and the Oracle® RDBMS (up to 10g), is the fourth generation of this product. TRADAS 2006 is complete and ready for delivery and installation.

TRADAS 2006 offers many improvements over the earlier versions of the product. These include:

• Calculation of site-specific HPMS statistics.
• Support for turning movement counts.
• New annual phase 4 "site AADT” calculations that maintain current-year statistics for all sites, regardless of count year.
• Enhanced support for the modification of site attributes.
• Optional Count Scheduler that provides a count schedule, field sheets, and up-to-date status information about the short-term count program.
• The same comprehensive features available in the earlier versions, and more.

TRADAS is designed to meet the data processing requirements of the American Association of State Highway Transportation Officials' (AASHTO’s) Guidelines for Traffic Data Programs. These guidelines incorporate the recommendations of the Federal Highway Administration’s (FHWA’s) Traffic Monitoring Guide and the Highway Performance Monitoring System Field Manual.

TRADAS processes nearly all types of mainline traffic data (e.g., roadway volume, speed, vehicle classification, length classification, and weight). Data from both permanent sites and short-term counts are accommodated. The system performs a wide range of services to assist the client in producing high-quality traffic data. These include automatic detection of device type, five levels of quality control (device, channel, count, monthly statistics, and annual statistics), data summarization, data and statistics status management, standard and ad hoc reporting, and database management.

The system also produces the TRADAS Public Database, which is a mechanism for the controlled dissemination of traffic data in a simple form. This is an Oracle database that can be easily accessed through a variety of tools. We encourage the use of the Microsoft Office product line for this purpose. We have developed a series of views that can be used in Microsoft Excel and Microsoft Access to make Public Database access a simple task.

The system maintains statistics at a variety of aggregation levels, making both detailed and summary information immediately available to the user. In addition, Chaparral, with its exclusive focus on traffic data, keeps the system current with new requirements. For example, we will provide the vehicle weight and classification data requirements for the new Mechanistic-Empirical Pavement Design Guide software.

The importance of traffic data expertise and experience cannot be emphasized too much. Chaparral has been exclusively in the traffic data software and research business since 1988. Over the past decade, there have been several efforts to develop custom solutions for traffic data processing. These have met with only marginal success. The problem of communicating traffic expertise to software developers is a leading reason for the high development risk in these ventures. At Chaparral, our programming staff is expert in both software technology and traffic data. We have leveraged this experience into an excellent and comprehensive product that you can install with no development risk.

Most important, we have a highly skilled support department to provide long-term customer service for TRADAS users. Staff members are knowledgeable of both the TRADAS software and of traffic data in general. This permits them to respond to a wide range of problems that often require more traffic knowledge than software knowledge.

The strength of our product, combined with our excellent support, make TRADAS the ideal foundation for an excellent traffic data collection and analysis program. If you need such a solution, we will be happy to provide an on-site, detailed demonstration of TRADAS 2006. Contact Chaparral at (505) 438-7353 or e-mail us at info@chapsys.com to arrange a demo, or to get more information about our capabilities.
