ITRE has a long standing history to offer different modeling and computing services. These services are supported by several deep data warehouses that ITRE has access to such as high resolution vehicles trajectory data in ITRE’s DATA lab. Modeling packages that are offered by ITRE are ranging from Highway Capacity Manual models to network based Triangle Regional Models. These modeling services along with microscopic simulations are used to assist transportation decision makers to better understand the problems. ITRE also provides assistance in developing a number of tools that are needed to analyze different transportation problems. Due to complexity of the methodologies, now a days using computational engines and tools are inevitable. ITRE has been centrally involved in developing tools for several national projects such as FREEVAL and STREETVAL for Highway Capacity Manual. Also, ITRE has developed necessary tools for local and state wide uses such as ARTVAL for NCDOT.
