Info

It is recommended that the City of Oakland continue to use pre-timed and actuated signal control and explore opportunities for traffic responsive signal control. Adaptive traffic signal control is not recommended in the near term for the City of Oakland until traffic adaptive systems have become more mature in the Bay Area. Thus, pre-timed, actuated, and traffic responsive signal control shall all be covered in the signal system functional requirements. 3.2 SIGNAL SYSTEM FUNCTIONAL REQUIREMENTS The following high-level requirements for the users of a new signal system were identified by the City: • Transportation Services and Electrical Services shall have the ability to monitor and control the City’s traffic signals from a central location on a real-time basis. • Transportation Services, in coordination with the Fire Department, shall have the ability to adjust signal timing in response to incidents and emergencies on a real-time basis. These high-level requirements address the City of Oakland ITS Program Goals and Objectives described in Section 1, as shown in Table 3.1 below. Table 3.1: City of Oakland ITS Goals and Objectives Mapped to High-Level Signal System Requirements Goals Objectives High-Level Requirements • Improve vehicle travel times in Transportation Services congested corridors by and Electrical Services coordinating traffic signals shall have the ability to and responding to changing monitor and control the traffic conditions.

Reduce congestion and improve traffic flow by developing an integrated roadway and traffic demand management system that provides an appropriate mix of mobility and accessibility throughout the City. Improve the environment by reducing fuel consumption and air pollutants caused by vehicles. Provide safe streets. • Improve safety and security of motorists, transit users, bicyclists and pedestrians. • Coordinate transportation operations with emergency service providers in response to incidents and emergencies. Transportation Services, in coordination with the Fire Department, shall have the ability to adjust signal timing in response to incidents and emergencies on a realtime basis. City of Oakland ITS Strategic Plan 22 September, 2003
In the Needs Assessment workshop, several functional requirements for the central signal system were discussed to help achieve each of the above high-level requirements. These requirements are described below. High-Level Requirement: Transportation Services and Electrical Services shall have the ability to monitor and control the City’s traffic signals from a central location on a real-time basis. Functional Requirements: • The central signal system shall provide real-time map display of traffic signal controller status on a citywide and corridor basis. • The central signal system shall perform the following modes of operation: time of day, actuated, traffic responsive and free operation. • The central signal system shall provide real-time alarms and reports of malfunctions, with the capability to automatically or manually institute maintenance functions. • The central signal system shall provide a database management system with upload and download capabilities of complete controller databases. • The central signal system shall graphically display intersection layouts. • The central signal system shall provide security options. • The central signal system shall provide for remote access interface options. Access to the central system will be possible not only from the TMC, but from staff workstations elsewhere in the building, the MSY or directly from the field. • The central signal system shall be able to collect, report and store traffic volume, occupancy and speed data from vehicle detection systems. • The central signal system shall interface with other software and systems. At a minimum, it shall have the capability for data transfer between software such as Synchro, Traffix, HCM, and traffic count database management programs, as well as GIS and CAD software such as ArcView and AutoCAD. High-Level Requirement: Transportation Services, in coordination with the Fire Department, shall have the ability to adjust signal timing in response to incidents and emergencies on a real-time basis. Functional Requirements: • The central signal system shall have the capability for communicating with neighboring agencies, such as the following capabilities and features: • Incident Management and Detection to allow staff to have a semi-automated or an automated means to detect incident and to take appropriate action. • Caltrans inter-tie to allow data and video sharing with Caltrans. • CHP inter-tie to allow data and video sharing with CHP. • MTC’s TravInfo® inter-tie to allow data sharing with the regional traveler information system. • AC Transit and BART Inter-ties to allow data sharing between the City of Oakland and the transit agencies operating in the region. • The central signal system shall interface with ATMS elements such as CCTV, trailblazer signs and DMS to improve incident management capabilities. • The central signal system shall have the ability to implement incident management plans, such as an “Evacuation Plan” for large-scale emergencies.
