To help ensure that participants understand the lessons, each topic or session includes one or more exercises. At the end of the course, participants can take an additional quiz to receive 0.6 credits through the International Association for Continuing Education and Training.
DYNASMART-P is a state-of-the-art planning tool that engineers can use to address complex transportation planning and operations issues simultaneously. Researchers at the University of Maryland developed the software under the Federal Highway Administration's (FHWA) Dynamic Traffic Assignment research project. Version 1.0 of DYNASMART-P is available from the Center for Microcomputers in Transportation (McTransTM) at In addition, FHWA recently completed testing of an updated version of the software, which will be available from McTrans in June 2006. The new version reduces the computer memory required for using the software and includes new features, such as a pricing element that enables planners to specify a toll that depends on the time of day.
The new UHPC bridge features a single-span, three-beam cross section. Before the bridge was built, researchers at the ISU Structural Engineering Research Laboratory conducted tests on a UHPC beam of the type intended for use on the bridge. The purpose was to verify the beam's shear strength, or strength against failure when a component splits into two parts that slide past each other, and flexural, or bending, strength. In the shear test, the beam carried an applied load of 2,860 kilonewtons (643 kips) before failure. In the flexure test, the first cracks appeared as expected at an applied load of 1,140 kilonewtons (256 kips).
