STAYIN' ALIVE ON 25

This article describes how the California Department of Transportation (Caltrans) and the California Office of Traffic Safety, in conjunction with local and regional agencies and dedicated public participation, partnered to promote safety and reduce traffic accidents. Spurred by housing and industrial development and a change of function from a farm road to a commute artery, Highway 25 experienced a dramatic increase in traffic, with the average daily vehicles increasing from 9,000 to 18,000 in ten years.. Along with the increase in travel came a large increase in accidents. Public pressure led Caltrans and the California Highway Patrol into forming a two-pronged response. With the formation of the Highway 25 Safety Task Force, Caltrans initiated a safety project which involved a soft barrier median, rumble strips, and shoulder widening. In addition, the corridor was designed as a daylight headlight section, and signs were placed warning drivers of radar enforcement and aircraft patrols. The second part of the response involved the corridor being placed in Caltrans cross- centerline accident program. This enabled implementing further improvements, such as a 1.2m median rumble strip with a raised and inverted thermoplastic stripe, shoulder reconstruction, widening and rumble strips, and a clear recovery zone. Completed in late 2002, the success of the project can be seen in a dramatic reduction of accidents and fatalities. The article concludes by noting that despite this success, traffic is expected to double along the route in the next 20 years. In addition, Route 25 runs through two disparate counties with differing priorities for improvements.
