The Symposium, held regularly since 1968, brings together researchers, practitioners, consultants, transportation agencies, and industry to present and review contemporary research on issues related to the visual communication of information within the general transportation infrastructure. The Visibility Symposium is sponsored by the following TRB committees: * AND40 Visibility, in collaboration with: * AND10 Vehicle User Characteristics, * AND20 User Information Systems, * AHD55 Signing and Marking Materials, * AHB50 Traffic Control Devices, * AHB55 Work Zone Traffic Control, and * AHB60 Highway/Rail Grade Crossing. Papers presented at the 18th Biennial TRB Visibility Symposium held on April 17-19, 2007, in College Station, Texas, are available online. Sessions at the symposium explored vehicles and roadway lighting, design of traffic control devices, pavement markings, pedestrian and roadway visibility, and design and performance of road signs.

With the advances in display technology we will have the ability to present the driver significantly more information than ever before. While more information can be good, it may also overload the driver. The purpose of this workshop is to engage the participants from the Visibility Symposium in a discussion on the impact of new information display technologies on the driver and road safety. As part of the Workshop we will identify inter-disciplinary visibility research needs relative to the sponsoring committees. Topics to be discussed: * Inside and Outside the vehicle considerations * Heads-up displays * Active warning devices * Variable information signs/displays * Bigger & brighter signs and markings * Impact of advance vehicle lighting technology * Impact of Vehicle-Infrastructure communication (Author/publisher)
