to view Short Range Transit Plan FY 2007/2008 - Tri Delta Transit

• From Somersville Road future eBART and transit center toSoutheast Antioch and perhaps Brentwood via Highway 4, LoneTree Way, Lone Tree Way/Highway 4 transit center, FairviewAvenue, and Balfour Road to Brentwood transit center.• From Somersville Road transit center to Hillcrest transit centervia Highway 4, new BRT connection to Oakley Road, downtownOakley, then Brentwood Boulevard to Brentwood transit center.Fifth, improved vehicle designs such as the EmX design with left-sidedoors may maximize BRT design flexibility as it has in Eugene-Springfield. While detailed BRT design issues will be site-specific, theability to use platforms on either side of a bus may allow installation ofstations in locations otherwise precluded due to narrow rights of way,otherwise awkward traffic circulation, etc. Potential BRT patronagecould also warrant purchase of articulated vehicles (there is no designlimitations on 40-foot vehicles with left-sided doors, such as used bystandard electric trolley coaches in a Boston tunnel). See Figure 4.20.Figure 4.20 EmX Vehicle with Left-Side DoorsFinally, use of BRT vehicles with doors on both sides of the vehicleincreases the feasibility and cost-effectiveness of an elevated BRTstation over the current BART tail tracks at the Bay Point station, withdirect escalator access to the BART station platform. With only rightsidedoors, a BRT station would have to be at least 60 feet wide; thecurrent BART right-of-way is only 50-feet wide. By staggering the BRTarrival and departure areas, with left-hand alighting and boarding froman island platform, a structure less than 40 feet wide is possible.Together with 2 bus bays for alighting and 2 boarding bays–with a BRTbridge to the existing bus transfer area to allow a second stop forconnections to local routes and sufficient space for BRT vehiclelayovers—this concept would be much less massive than a facilityconstructed to conventional roadway standards. While such a conceptwould require about 0.6 miles of two-way elevated bus way connectingto the existing HOV lanes, it may be worth the $100 million cost+ dueto a capacity of over 100 bus arrivals and 100 departures per hour,and significantly shorter access times to the BART station platform,compared to walking times from the existing bus transfer facility.Please refer to Figure 4.21 for a drawing of this concept.82
