Single-point Urban Interchange
A single-point urban interchange (SPUI, or ), also called a single-point interchange (SPI) or single-point diamond interchange (SPDI), is a type of highway interchange. The design was created in order to help move large volumes of traffic through limited amounts of space efficiently. Description A SPUI is similar in form to a diamond interchange but has the advantage of allowing opposing left turns to proceed simultaneously by compressing the two intersections of a diamond into one single intersection over or under the free-flowing road. The term "single-point" refers to the fact that all through traffic on the arterial street, as well as the traffic turning left onto or off the interchange, can be controlled from a single set of traffic light, traffic signals. Due to the space efficiency of SPUIs relative to the volume of traffic they can handle, the interchange design is used extensively in the reconstruction of existing freeways as well as constructing new freeways, p ...

Pontis
Pontis is a software application developed to assist in managing highway bridges and other structures. Known as AASHTOWare Bridge Management since version 5.2, Pontis stores bridge inspection and inventory data based on the U.S. Federal Highway Administration (FHWA) National Bridge Inventory system coding guidelines. In addition, the system stores condition data for each of a bridge's structural elements. The system is designed to support the bridge inspection process, recommend a bridge preservation policy, predict future bridge conditions, and recommend projects to perform on one or more bridges to derive the most agency and user benefit from a specified budget. The system uses a Markovian Decision Process to model bridge deterioration and recommend an optimal preservation policy. It uses the Markovian model results, in conjunction with a simulation model, to predict future conditions and recommend work. History In 1991, the FHWA sponsored the development of a bridge management ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
