摘要：	The purpose of this is to attempt to clarify some of the issues pertaining to bicycle on freeways. Specifically, the goal of this project is to develop policy recommendations and guidelines for bicycle and pedestrian use of freeway shoulders. Based on the literature and investigations done as part of this study, highway bicycle collision rates per mile of bicycle travel are an order of magnitude higher than collision rates for motor vehicle traffic. Bicycle collisions are no more frequent on bridges and in tunnels than on the approaches to the bridges and tunnels. Overall vehicle collision rates are no higher on freeways open to bicycles than they are on adjacent highways open to bicycles. Most freeway pedestrian collision involve individuals who enter the freeway in a vehicle and leave the vehicle. A disproportionate share of these pedestrian collisions are related to installing and removing tire chains. The project recommendations include: enhanced efforts to inform drivers and passengers of the dangers related to exiting their vehicles on a freeway, a bicycle counting program to establish bicycle ridership and collision rates, a requirement to wear a helmet and posses a drivers license to operate a bicycle on the freeway, a minimum of eight foot pave shoulders on freeways that are open to bicycles, and restrictions relating to bicycles crossing freeway ramps on the freeway side.
