Tiedback Walls Untie Intersection
The intersection of Gallows Rd. and Arlington Blvd. in Virginia's Fairfax County required separation. Tiedback retaining walls, which required only 18 in. instead of the 18-22...
An Analysis of Traffic Signal Safety Improvements
Identifying high accident rate locations and determining that they have an overrepresented type or pattern of accidents is an important first step in the safety improvement process. However,...
Coordination of Interconnected Arterial Traffic Signals
Present analytical methods and computer programs offer capabilities of optimizing the traffic signal coordination for a series of signalized intersections. Recently, transportation research...
POSIT?An Interactive Timing Optimization Program
A window-oriented, microcomputer-based signal optimization program called POSIT (Program for Optimizing Signalized Intersection Timing) has been developed that provides traffic engineers...
Assessment of Software for Traffic Signal Analysis
The main objectives of this paper were to conduct an up-to-date comprehensive inventory of traffic signal analysis software, select pertinent programs that operate under the MS-DOS environment,...
Highway Capacity Manual Revisited
The forthcoming third edition of this manual of highway and traffic engineering, due in 1985, will significantly change how highway capacity is analyzed. Of the edition's...

The CRT Computer-Graphics Terminal: Indispensible Design-Aid for Some Structural Engineers
Putting the benefits of computer graphics within the cost reach of many consulting firms are: the development of low-cost ($3,000 to $10,000) storage-tube CRT graphics terminals; and the...
Computerized Traffic Signals; Good for My City�
Good question. The answer is, It depends. On freeways, some computer-controlled on-ramp signals are dramatically speeding rush-hour traffic. The situation is more complicated when you...
