| A successful traffic data program
has many components. Of course, having reliable and effective traffic
data collection equipment is the beginning point. Next, one needs
excellent traffic data collection, quality control, and analysis
software such as Chaparral Systems Corporation's (Chaparral's)
TRADAS (TRAffic DAta System). However, even after quality traffic
data are collected and summarized, there are other issues that
must be addressed to maintain an effective traffic data program.
These involve answering such statistical questions as "How
should we group automatic traffic recorders (ATRs) to establish
the most useful factor groups?" "How many and what type
of permanent traffic recorders do we need for computing adjustment
factors?" And, "How many short-term counts do we need
to provide effective coverage of our system?"
Chaparral has developed the expertise and procedures to answer these questions. We have performed numerous statistical analyses of traffic data in our role as Technical Assistance Contractor for Traffic in the Federal Highway Administration's (FHWA's) Long-Term Pavement Performance (LTPP) program. Our current efforts include analyses in support of revisions of the FHWA's Traffic Monitoring Guide. This background makes us most qualified to perform traffic data analyses of any level of complexity. | Examples of the types of analysis
products we can offer are:
To minimize costs, we perform these analyses at Chaparral's offices in Santa Fe, New Mexico. We have flexible pricing arrangements that allow these services to be provided on either a one-time basis or as recurring services. These pricing arrangements include fixed annual fees and transaction-based pricing. All of our analysis products are fully supported by our research staff. They provide full support to assist you in data aggregation and transfer, analysis design, and any other technical issues related to these analyses. Each analysis product includes a written report. We can produce these reports as printed documents, or as Web-ready documents, if the client wants these products to be generally accessible. These reports, and the underlying services on which they are based, can provide the "missing links" you may need to develop an effective and useful traffic data collection and analysis program for your organization. |
