Encourag dvlopmnt of a systm of hik/bik trails throughout th shorlin ara. Countywid Comprhnsiv Transportation Plan Th 2009 Countywid Comprhnsiv Transportation Plan (CTP, 2009a) stablishd th following goals for th Contra Costa County transportation systm:. Enhanc th movmnt of popl and goods on highways and artrial roads, 2. Manag th impacts of growth to sustain Contra Costa s conomy and prsrv its nvironmnt, 3. Expand saf, convnint and affordabl altrnativs to th singl-occupant vhicl, and 4. Maintain th transportation systm ENVIRONMENTAL SETTING ROADWAY TRANSPORTATION Existing Circulation Ntwork Th routs to and from th projct sit ar dscribd blow. Figur 3.8- shows th projct study ara and study intrsctions locations. Intrstat (I-) - is situatd in clos proximity to th projct sit. This frway bgins in San Joaquin County at a junction with Intrstat 5 (I-5) and passs through th San Francisco Bay Ara (Bay Ara), which includs th citis of Livrmor, Plasanton, and Oakland. I- conncts with I-80 whr it srvs th southast Bay Ara, thn continus north past th projct sit to connct with US-0 in Marin County. This frway bcoms th Richmond/San Rafal Bridg, wst of th Wstrn Driv offramp at th toll plaza. In th immdiat vicinity of th projct sit, I- has a total of six lans, thr in ach dirction. Thos travling wstbound on I- can xit at Wstrn Driv to accss th Projct Sit. Currntly thr is no dirct accss to Wstrn Driv travling ast on I-. If travling ast on I- accss to th projct sit would b via th Castro Avnu xit. Analytical Environmntal Srvics Point Molat Mixd-Us Tribal Dstination

4 Intrstat 80 (I-80) - is a major ast-wst rgional rout that travrss in a north-south dirction in th vicinity of th projct sit. Currnt accss to th projct sit is by xiting I-80 at Richmond Parkway or I- wstbound. Unitd ats 0 (U.S. 0) - is currntly six lans in th vicinity of I-, but is plannd to b ight lans (thr lans plus a high occupancy vhicl lan in ach dirction) with nw auxiliary lans. U.S. 0 is th major north-south frway in Marin County xtnding into Sonoma County to th north and continuing south to San Francisco and points byond. Richmond/San Rafal Bridg - is a 5.5-mil-long bridg spanning th southrn nd of San Pablo Bay. Th Bridg conncts th City of Richmond with th City of San Rafal along I-. Thr ar two wstbound uppr lvl bridg dcks and on lowr lvl bridg dck. Richmond/San Rafal Bridg Toll Plaza - oprats in th wstbound dirction and has a total of svn toll lans/booths. Fiv of th svn lans/booths ar dsignatd for auto cash/fastrak. On lan oprats as a dsignatd carpool/fastrak lan and th rmaining lan oprats as a Fastrak-only lan. Richmond Parkway - xtnds from Castro rt and conncts with I-80. This roadway is classifid as an xprssway, and varis in th numbr of lans. In th vicinity of I-, Richmond Parkway has two lans in ithr dirction, both of which mrg with Castro rt. Castro rt conncts with Wstrn Driv. San Pablo Avnu - provids paralll accss to I-80 from Oakland to Hrculs. San Pablo Avnu is a four-lan rgional artrial, providing north-south accss, dsignatd by th County as a Rout of Rgional Significanc. San Pablo Avnu provids an altrnativ accss point to th projct sit via Richmond Parkway. Canal Boulvard - is a north-south roadway varying from four (south of Cutting Boulvard) to six lans (north of Cutting Boulvard) and xtnds from th Richmond Parkway (south of I-) to th Point Potrro ara. Barrtt Avnu - is a cross-town artrial running ast wst through Richmond and varis from two to six lans through Richmond and El Crrito. Barrtt Avnu passs through cntral Richmond, whr it has six-lans with Class II bik lans. Wst Macdonald Avnu - is locatd south of th Richmond Bay Ara Rapid Transit (BART) station and has historically srvd as th City s main strt, which provids accss to downtown and th civil cntr complx.

Pak traffic congstion in th rgion tnds to occur during th commut priods btwn 7:00 and 9:00 AM and 4:00 and 6:00 PM. Th pak hour is dfind as th highst on hour priod during ach of th two hour tim priods. Pak hour counts wr collctd in lat May and arly Jun (bfor school summr vacation priod) 2007 by DMJM Harris/AECOM for 29 study intrsctions. Th California Dpartmnt of Transportation (Caltrans) providd 2007 avrag daily traffic (ADT) information for th US 0 frway mainlin and intrchang ramps. Th daily mainlin volums wr calibratd with Caltrans pak hour volum data. Abrams and Associats prformd traffic counts at th Richmond/San Raphal Bridg Toll Booth Plaza in Dcmbr 2008, at th intrsction of Richmond Parkway/Grtrud Avnu in March 2009, and at th intrsction of Richmond Parkway/I-80 On/Off Carpool Ramps in April Existing conditions for th study intrsctions wr analyzd using th Contra Costa County Transportation Authority (CCTA) LOS program. LOS is both a quantitativ and qualitativ grading systm to charactriz traffic flow conditions. Ranging from LOS A to F, with A rprsnting th optimal oprating conditions whr roadways ar uncongstd and fr flowing to F dpicting th worst oprating conditions whr traffic xcds capacity and has stop-and-go flow conditions. Th CCTS LOS program was dvlopd basd on mthodologis rportd in th Transportation Rsarch Board (TRB), Circular 22, Intrim Matrials on Highway Capacity, 980. Th TRB is a planning-lvl mthodology that projcts in CCTA jurisdiction us to dvlop LOS and dlay paramtrs. Tabl 3.8- prsnts th CCTA LOS dfinitions for signalizd intrsctions. Tabl prsnts th 2000 Highway Capacity Manual (HCM) LOS dfinitions for unsignalizd intrsctions. Tabl prsnts th 2000 HCM LOS for basic frway sgmnts, mrg and divrg aras, and waving sgmnts. Th HCM is prpard by th TRB and provids a collction of stat-of-th-art tchniqus for stimating th capacity and dtrmination of th LOS for transportation facilitis.
