There are many other features contained within the TRADAS product. The text below describes a few more features but for more information on a comprehensive list of TRADAS product features, please request further information by sending e-mail to info@chapsys.com or call 1-877-230-2974 ext. 1103.

The system supports up to eight different site identifier types used for site name resolution purposes which is know as the site identification or naming convention. Each identifier may have up to eight different data references for the same site. For example, a county, route, and mile-point identifier would be a single site identifier/reference type. For more information on this feature, click here.

The system allows a user to define site specific details such as the number of lanes and the direction of travel for each lane. This is handled in the system by a road descriptions dialog box. In the Road Descriptions dialog box, the TRADAS user can define the "roadway" as the total volume for the site for all lanes in all directions, the volume by direction (Pos Dir - total volume in the positive direction), and by lane (Pos Lane 1 - total volume in lane 1 in the positive direction.

The system also provides automatic association of raw data files to sites, lanes, and collection methods. Configuring sites to handle these automatic associations requires the creation of a binding rule. Once a binding rule is created, associations (such as a site that has 4 lanes should have 2 lanes in one direction and 2 in the other direction) for all counts that follow agency count identification rules are automatically applied. The system allows a user to create a “Binding Rule” that executes while loading and processing data that specifically binds the raw data file immediately to the given site location and lane as defined by the binding rule for that site. When future files are run for that same site and if the automated process based on agency count identification rules fails, all the binding rules in the system are checked and used if applicable.

The system allows channels of data to be bound to lanes, to a single direction, or to the entire roadway. At the time of binding a channel to a road element, it is also bound to a bin scheme and a collection method (AASHTO-based Continuous or AASHTO-based Short-term) regardless of binding method. Binding is completed before all count-resolution and most quality control processes allowing the system to execute quality control checks that include context specific data checks. The site database records the number of lanes in each direction to allow the validation of the count channel mapping.

The TRADAS database site table allows the storage of agency-specific (custom) fields, as well as a description of these fields. For example, some agencies track sites by the City Federal Information Processing Standard (FIPS) Code, Region, or DOT District. Other customized fields might include the Count Station Facility Code that is a numeric value indicating the type of site such as a zero that indicates a continuous count station. Other customized fields might include a main site type such as axle-based classification site. Another example might include an interstate inter change code or a station identification status such as on-system or off-system designation. If the agency accepts traffic count data from other data sources and chooses to track the data source, a customized field which designates the site by data source can be configured in the system.

The site table stores up to three site-specific images, maps or documents needed for reporting. This feature allows TRADAS users that do not or have not visited the site to view site conditions through a photograph. Maps that can be loaded help to identify the site location and documents such as site-specific engineering plans can be loaded. Some agencies might choose to load continuous count station engineering drawings that show the site configuration details such as the number of inductive loops installed in each lane, the depth of pavement that was cut for each inductive loop, or the location of continuous count signal cabinet.
