Assessment of Current and Emerging Broadband Wireless Technologies for VDOT?s Operations Program
The Virginia Department of Transportation's (VDOT) Operations Program depends considerably on communications between Intelligent Transportation Systems (ITS) field devices and Transportation Operations Centers (TOC). The future of transportation operations is expected to grow beyond fixed devices to incorporate vehicle-to-vehicle and vehicle-to-roadside wireless communications as well. Fiber optics and traditional telephony wire line solutions provide reliable communications links; however, they can be expensive, bandwidth-limited, or unavailable in some areas. Broadband wireless communications is proving to be a viable alternative to wired mediums for providing connectivity to field devices. This report assesses the current state of available wireless technologies and presents recommendations for usage in Department of Transportation (DOT) applications.
