摘要：	This report describes the draft Concept of Operations that has been developed for the Integrated Corridor Mobility (ICM) program by the I-880 corridor team. The I-880 corridor team has defined this Concept of Operations (ConOps) based on two primary principles: (1) it must improve overall corridor performance by meeting the needs of the local stakeholder agencies, within their practical operational, institutional and financial constraints; and (2) it must focus on integration of pre-existing systems rather than on implementation of new equipment or infrastructure. The I-880 corridor is a truly multimodal corridor, including a robust freeway network, major arterials which carry high volumes of local traffic as well as absorb diversion from the freeway networks, a transit network which includes the Bay Area Rapid Transit (BART) rail system and multiple AC Transit bus transit lines, and heavy freight movements with trucks comprising between 4%and 11%of the average annual daily traffic in the corridor. Transportation management systems (TMS) have been widely deployed in the corridor for many years including: (a) ramp metering on I-880;( b) HOV lanes and HOV bypass lanes for ramp meters; (c) incident and emergency management systems on all freeways; (d) changeable message signs on freeways; (e) electronic toll collection systems (FasTrak); (f) coordinated traffic signal systems on major arterials; (g) BART transit management system; (h) bus transit with signal priority capabilities and AVL; and (i) transportation management centers for freeways, arterials, BART, bus transit and the Port of Oakland. Transportation facilities in the corridor are highly instrumented with real-time data collection systems. An institutional integration/coordination setting is already in place: the Metropolitan Transportation Commission (MTC), California DOT (Caltrans), Alameda County Congestion Management Agency (ACCMA), BART, Alameda-Contra Costa Transit District (AC Transit), and cities in the corridor have a history of cooperation. / Supplementary Notes: Sponsored by Department of Transportation, Washington, DC.
