events, or during unforeseen incidents, or along evacuation routes during siren emergencies. TBS Recommendations - Based on the stakeholder input, TBS could be an effective traffic control device around the Coliseum area, along detour routes during major incidents or along predetermined evacuation routes during emergencies. During incidents on the freeway, TBS could be used to guide motorists along a detour route and direct them back to the freeway downstream of the incident. TBS could be implemented as a low cost alternative to DMS or could be used in conjunction with DMS. 4.2.5 Highway Advisory Radio HAR systems are usually located at roadside stations and communicate locally relevant traveler information to all vehicles in the vicinity of the station. They are commonly "broadcast only" (infrastructure to vehicle) systems using the conventional AM broadcast band radio in the vehicle; however, FM broadcasts are becoming more prevalent. HAR can provide travelers with information regarding construction activities, special events, road closures or hazards, inclement weather, traffic congestion, incidents, alternate route guidance, and traveler information concerning local attractions. The transmission range of traditional HAR systems is limited to a few kilometers. The Federal Communications Commission (FCC), initially authorized traveler information stations (TIS) which include HAR, for use in the United States in 1977. These systems also are used by airports, train and bus stations, national, state and regional parks, counties and local municipalities, sports arenas, convention centers, and other entertainment venues, for disseminating traveler information. HAR uses AM or FM radio frequency spectrum. Until approximately two years ago, the AM broadcast band encompassed 530 kHz to 1610 kHz. Many automobile AM radios operate only within this range. Manufacturers are now modifying their equipment and most radio models sold in the last two years tune from 510 to 1710 kHz which are the new limits of the AM broadcast band since an FCC ruling in April 1992. All 1993 and later new vehicle radios will tune from 510 to 1710 kHz. HAR Recommendations - HAR has already been implemented on 1700 AM by the Oakland International Airport to provide parking information and information on construction conditions. The Port of Oakland has indicated that it would not be feasible to share this HAR station for other traffic information purposes. HAR has also been implemented for Coliseum events on 1530 AM to help guide motorists into and out of the Coliseum area at the beginning and end of special events. It is not recommended that the City of Oakland to implement any more HAR stations at this time. 4.2.6 Parking Guidance Systems (PGS) Results of the City workshop identified the need for a PGS for the Oakland International Airport and possibly the downtown Convention Center parking garage. The Airport has a main garage near the Airport Terminals and a large remote lot that are ideal candidates for PGS. PGS have been used in Europe and Asia for nearly fifteen years but are relatively new to the United States but they are gaining in popularity. In fact, the City of San Jose has City of Oakland ITS Strategic Plan 42 September, 2003
ecently completed the design of a PGS for their downtown area but its implementation is pending further funding. Through advanced computer technology and electronic signs, a PGS informs motorists in real-time of the availability of parking. A PGS is comprised of three major elements: • Central Computer • Garage Electronics • Parking Guidance Signs Central Computer System The operation of the PGS occurs at a central computer system typically located at city offices. The central computer system communicates with computers in parking facilities and electronic signs located along major streets. A typical central computer system includes a server, modems, workstation, graphics terminal, printer, and software that allow for central control and management of the system. Garage Electronics Each parking facility has a computer that tracks the number of vehicles in the facility and then sends the information to the central computer system. Occupancy data can be collected using inductive loops, electrical impulses from barrier gates, or direct connection to the revenue control system in the facility. Operators at the parking facility can access a user interface to reset or update the occupancy data if needed. Parking Guidance Signs Parking guidance signs provide the real-time parking information about spaces available and direct drivers to the parking facility. Signage and graphics are located where they can provide the driver with sufficient advance notice that a decision point is approaching. Parking guidance signs are a combination of conventional static signing with a small electronic sign insert, similar to DMS used in Europe (see figure to right). The size of each sign panel is commonly about 60” long, 18” tall, and 6” deep. The electronic part of the sign uses technology similar to large freeway message signs, except on a much smaller scale. Small parking guidance signs are also commonly placed at the entrances to the parking facilities to confirm to drivers the number of available spaces. PGS Recommendations - The Port of Oakland already has plans to implement a PGS in their new parking structure. The City of Oakland should also consider implementing a PGS for their downtown Convention Center or possibly at the Oakland Coliseum. City of Oakland ITS Strategic Plan 43 September, 2003
