Fixing America's Pedestrian Safety Problem   TM+E June-July 2003   Tamara Redmon
In response to the pedestrian fatality rate, many states and localities are looking at non-traditional measures and devices to improve pedestrian safety. Some of these devices have been included in the most recent revision of the Manual on Uniform Traffic Control Devices (MUTCD), which is the standard for all signs, signals and pavement markings on roads open to public travel. Some of the devices that are not in the MUTCD are currently being considered for inclusion.

ITS on a Rocky Mountain High   TM+E June-July 2003   Debra Otto

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.
