This data is presented in Table 1.4. <strong>Transit</strong> share of <strong>to</strong>tal commutertrips exceeds 8% in Bay Point and Pittsburg within 0-4 miles of theBART station. <strong>Transit</strong> share is about 4% in Antioch, which is locatedbetween 7 and 13 miles away from BART. <strong>Transit</strong> share declinesfurther <strong>to</strong> only about 2% in both Oakley and Brentwood, between 15and 21 miles from BART. Discovery Bay’s transit mode share is only1.4%, at a distance of 28 <strong>to</strong> 31 miles from Pittsburg/Bay Point BART.This direct relationship between mode share and distance from BARTsuggests that high quality transit service, whether rail such as theproposed eBART line, or “bus rapid transit” (BRT) could potentiallyincrease overall transit usage. The potential for BRT <strong>to</strong> supplementexisting BART service and the proposed eBART route is examined inChapter Four.Table 1.4 <strong>Transit</strong> Share of Work <strong>Tri</strong>psTypical Mileage <strong>to</strong> <strong>Transit</strong> CommuteCommunityBay Point BARTShareDiscovery Bay 28-31 miles 1.4%Brentwood 20-21 miles 2.3%Oakley 15-16 miles 2.1%Antioch 7-13 miles 4.4%Pittsburg 3-4 miles 8.3%Bay Point
