Problem Statement Transfer mobility measurements are used to help predict vibration and ground-borne noise impacts from transit and rail systems and also to evaluate the effectiveness of vibration mitigation techniques.…
Problem Statement The operation of steel-wheeled transit vehicles on steel rails may develop short-pitch corrugation of the rails. The interaction of the wheels rolling over the corrugated rails generates noise…
TERI Administrator Note (May 2011): Similar research under SHRP C09 project has addressed this issue. (http://144.171.11.40/cmsfeed/TRBNetProjectDisplay.asp?ProjectID=2348) Problem Numerous organizations at the federal, state, and local level have a stake in…
Problem Statement The specific noise issue in the vicinity of at-grade rail crossings is locomotive warning horn and crossing bell sounds, which cause significant noise impacts. The acoustic signatures of…
Problem The transportation sector is vital to the economy of the United States. It provides the critical links between industries and to their customers and it is the network for…
Problem Statement Vibration propagation through the ground is physically very similar to the propagation of noise through the air. Vibration and noise are similar in other respects as well; however,…
Problem States and metropolitan planning organizations (MPOs) are developing and evaluating transportation plans and programs on an ongoing basis. There is increasing awareness that future climate conditions may affect the resilience…
Problem States and metropolitan planning organizations (MPOs) are developing and evaluating transportation plans and programs on an ongoing basis. At the same time, many of them are also developing climate action…
TERI Administrator Note – Similar research topic funded as SHRP C09 – Incorporating Greenhouse Gas Emissions Into the Collaborative Decision-Making Process (Completed Feb 2011) RESEARCH PROBLEM STATEMENT State departments of…
Problem Current surface transportation systems depend on century-old internal-combustion technology that produces millions of tons of GHG’s and other emissions annually. Highway vehicles produce emissions while idling in traffic and in…
