Can't We Raise the Bar Just a Little?

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.

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.

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.

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.
