Evaluation of Modified Work Zone Traffic Control Devices at Business Accesses

摘要

Modified work zone traffic control devices at business accesses were evaluated ontwo Oregon Department of Transportation (ODOT) projects in 1999 and 2000. In Sweet Home, Oregon, on the Sweet-Home WCL-Foster Dam Rd. Section project, blue 'Temporary Business Access' signs were used at business accesses during driveway, curb, gutter and sidewalk construction. In Pleasant Hill, Oregon, on the Goshen-Pheasant Lane Section project, blue Temporary Business Access signs and blue tubular markers were used to delineate accesses to business during construction. The analysis of traffic count data taken at business accesses in Sweet Home before and during construction yielded inconclusive results. The effectiveness of the Temporary Business Access signs could not be determined from the results of the traffic count data. However, results of telephone surveys of motorists and businesses in Sweet Home demonstrated the usefulness of the Temporary Business Access signs. Twelve of 14 businesses said the presence of the Temporary Business Access signs helped customers locate their driveways. Additionally, 242 of 371 motorists surveyed noticed the signs, and 83% (171) indicated the signs helped them locate the business access.
