Technical Evaluation of Photo Speed Enforcement for Freeways
Author: Craig A. Roberts
Publisher:
ISBN:
Category : Radar in speed limit enforcement
Languages : en
Pages : 122
Book Description
Extreme speeding on urban-area freeways contributes to increased crashes resulting in fatalities, property damage, and increased maintenance and public safety costs. Photo speed enforcement systems (speed cameras) that automatically sense a speeding vehicle and photograph it and its driver have proven effective at reducing speeding violations, primarily on city streets and arterials. The use of this technology on high-volume, high-speed, multi-lane freeways is technically much more challenging, and largely untested. This research investigates if the current offerings of vendors can provide a viable technical solution in this freeway environment. Twelve ideal characteristics were established that are needed for a speed camera system to operate on Phoenix, Arizona, metro-area freeways. Six vendors were interviewed. Thirteen agencies that use speed camera systems were interviewed, although none were found with sufficient freeway operating experience to provide definitive information to design a field trial. Therefore, only a conceptual field trial and accompanying test plan were developed to explore the technical aspects of potential systems. Public opinion and countermeasures on speed camera systems were researched and reported. No current vendor offering meets all of the twelve ideal characteristics that were established. Advancements in speed camera systems continue, and it is logical to predict that they can be met in the future. One new technology that shows promise is "point-to-point," which tracks average speed between two points on a roadway. This research did not address the violation processing and management activities, but noted that these must be addressed before a field trial can proceed.

Improving Work Zone Safety Through Speed Management
Author: Norman M. Sommers
Publisher:
ISBN:
Category : Road work zones
Languages : en
Pages : 78
Book Description
Safety hazards are increased in highway work zones as the dynamics of a work zone introduce a constantly changing environment with varying levels of risk. Excessive speeding through work and maintenance zones is a common occurrence which elevates the dangers to both drivers and motorists in the work zone. Although most work zones are controlled by reduced speed limits or state law enforcement, driver adherence to these regulations and laws in very minimal, especially in work zones. Several studies have shown a correlation between speeding in work zones and traffic crashes which lead most traffic safety professionals to conclude that excessive speeding and speed variance are the contributing factors in a large percentage of traffic crashes, injuries or fatalities. The most influential factor in achieving speed compliance in the work zone is the driver's perception of heightened risk. The main objective of this study was to determine the safest and most effective countermeasure for the reduction of vehicular speeds within construction and maintenance work zones. The purpose of the simulator experiment was to determine the effectiveness of 20 countermeasures on the reduction of speed through work zones in a controlled laboratory setting. The literature review identified several past research studies utilizing speed reduction countermeasures in work zones and under normal traffic conditions. From this review, 20 countermeasures were selected for evaluation based upon discussions with ODOT personnel.The post hoc tests indicated that the presence of construction workers, presence of construction vehicles, law enforcement, speed photo enforcement and shifting lanes were most effective at reducing speeds in work zones. The least effective speed reduction countermeasures included 3 sets of 3 rumble strips, concrete barriers, other channelizing devices and changeable message signs with speed reductions less than 10 mph.
