Book Description
Principal findings of this study were that geometrics alone account for only a small portion of the variance in accidents and that no relationship could be established between fatalities and the geometrics studied. The geometrics studied include several types of interchanges, paved shoulders, sight distance, delineators, surface types, and other variables. Mathematical models were developed which can provide estimates of the average number of accidents on a particular type of highway or interchange, using the appropriate variables.

Book Description
In Virginia, when new construction or major reconstruction is planned, the current practice is for a location and design engineer to select the interchange type for a given location. The engineer relies upon projected traffic data, right-of-way needs, environmental concerns, safety, and project costs to determine which interchange configuration will most efficiently serve the needs of a certain area. The purpose of this study was to develop guidelines to aid designers in the preliminary selection of the optimum interchange type at a location. This study will provide engineers a starting point to begin their analyses. It is hoped that the development of these guidelines will result in reduced costs, improved levels of service, and increased uniformity. A number of sources were used to develop the guidelines. A literature and a nationwide survey of state engineers helped determine current methods for interchange selection. These surveys also assisted in determining the relative advantages and disadvantages of the various interchange types. Also, 10 interchanges throughout Virginia were studied in order to find their operational and safety characteristics. Extensive computer simulations of the interchange types were performed in order to determine traffic characteristics that affected operations at the interchanges. Based on all of these sources, some general guidelines for preliminary interchange type selection were created.

Book Description
The thirteen projects take as their subject a site of contested transportation infrastructure--the Sheridan Expressway. By proposing new typologies for this site, these studies seek to mediate the spaces in the city where local and regional meet. Referencing the introduction of the modern parkway into the Bronx, the grading of the Central Park transverse roads, and other works that have redefined the relationship between parks and roads, author Jonathan Solomon suggests a system by which large projects might again be built in American cities.

Book Description
Conceived as a set of "Flexible Standards," this new addition to the Pamphlet Architecture series proposes a new way of thinking about roadways in cities. By reexamining the urban expressway as a political, physical, and mythic manifestation of American culture, this compelling pamphlet serves as a design manual for planners, a novel atlas for drivers, and a collection of proposals that reaffirm the role of architecture in urban planning.
