| 摘要： | The objectives of this research included the following: (1) evaluation of measures and procedures that will alter or control the speed of motorists in work zones, (2) investigate the feasibility of using automated equipment to replace flaggers in work zones, (3) develop policy and guidelines for use of elevated platforms near traffic, and (4) evaluate the safety issues associated with mobile and short-term work activities. In an attempt to determine the effectiveness of various speed control measures in work zones, speed data were collected for several strategies including signs, radar displays, and police enforcement. It was determined that the largest reduction in speed can be achieved with the presence of police enforcement at the work site. The use of automated flagger devices were investigated, and it was determined that these devices have potential for application in long-term lane closures at work zone locations such as bridge deck repairs. Flashing STOP/SLOW paddles were purchased and provided to maintenance personnel for evaluation. The paddles were used by employees with mixed results in terms of their practicality and durability. Guidelines for use of aerial lifts/elevated platforms were developed, in conjunction with a typical application drawing for aerial work within an intersection. A handbook was developed to provide guidelines for traffic control in short duration and mobile work zones, with additional examples provided for short-term maintenance on two-lane and multi-lane roads. |
