Timing is everything   TM+E October 2003   Bill Wilson
Red-light running is a traffic epidemic in this country. Metropolitan transportation officials are trying to contain this killer virus that makes the infected think more about themselves than the safety of others.

Can't We Raise the Bar Just a Little?   TM+E June-July 2003   Philip J. Tarnoff
Signal timing projects have been shown to have benefit-cost ratios as high as 80:1, while ratios of 20:1 are common. Yet surveys of traffic signal operation have consistently shown that these important devices are receiving inadequate attention to ensure efficient traffic operation. The promise of ITS can only be met with improved traffic controls, which in turn suggests the need for increased emphasis on signal system operations.

Wireless Tools of the Trade   TM+E June-July 2002   Ken Szgatti
Spread Spectrum (S/S) radio modem usage in all aspects of the traffic industry is increasing on a daily basis. The major benefit of S/S technology is its ability to be deployed rapidly, without the challenge of regulatory issues or licensing.

Strengthening the Signal Industry   TM+E June-July 2002   Tim Gregorski
The International Municipal Signal Association’s 107th Annual Conference and 25th Annual School takes place Aug. 22-30 at the Hyatt Regency Crystal City, located in Arlington, Va. Operating under the theme “Meeting Today’s Challenges with Tomorrow’s Technology,” the event encompasses top-caliber schools, seminars and technical sessions dealing with a wide variety of transportation and public safety-related subjects, in conjunction with an exhibition area consisting of the industry’s top manufacturers of industry-related products and services.

A Brighter Future Ahead   TM+E June-July 2002   Sanjay Gupta
What has become more evident in recent years is that traditional incandescent lamp-based traffic signals are being converted to traffic signals which incorporate light-emitting diodes (LEDs). This article investigates the conversion of traditional traffic signals to those that incorporate an LED-based signal system, as well as the benefits of switching to an LED-based signal.

Traffic Management Field Trial   TM+E April-May 2002   John Templeton, P.E., and Robert E. Rees, P.E.
To address neighborhood concerns, the city of Concord, California, undertook a program to install temporary speed humps and traffic circles. The devices, made from recycled tires, were designed to be installed and removed in one day. The devices were tested for effectiveness and durability within the city’s maintenance yard before installing them on the street.

Real-Time's Rapid Growth   TM+E October-November 2001
The MTA designed Metro Rapid to make riding the bus more attractive. The new service uses the city’s computerized traffic signal control system to move special red-painted buses through intersections faster. Just as important, it has developed a new passenger information system that uses wireless electronic displays at a majority of its bus stops to improve rider morale.
