Transcription

1 A. Existing Conditions A 2002 conditions assessment was conducted fo the City fo use as a basis of compaison fo futue tanspotation system plan development. This chapte summaizes existing taffic and tanspotation opeations fo all the majo tanspot modes including: Moto vehicle, Tansit, Pedestian, Bicycle, Tuck, Ai, ail and pipeline. System Inventoy and Opeational Evaluation A physical and opeational inventoy of tanspotation system facilities in was conducted to povide a benchmak fo futue assessment of tanspotation pefomance in elative to desied policies. The study aea fo the Tanspotation System Plan includes and potions of unincopoated Coos County as shown in Figue A-1. Taffic Obsevations Taffic volume data (vehicle, tucks, pedestians, and bicycles) was collected duing August 2002 at seventythee intesections duing the evening peak peiod and sixteen duing the moning peak peiod. Agency staff and the consultant identified these locations as significant fo monitoing system pefomance. Supplemental taffic data fom ecent tanspotation studies and state histoical data also was applied in the base line evaluation. Opeational Analysis Taffic data was analyzed to evaluate aea taffic conditions including volumes and levels of sevice. Roadway pefomance was evaluated based on methods defined in the Highway Capacity Manual, Tanspotation Reseach Boad, 2000 and othe standads of engineeing pactice. Othe tanspot systems wee evaluated based on factos such as system continuity and geneal effectiveness. Field obsevations at majo oadways and intesections wee conducted to obseve actual taffic conditions, and to confim analytical evaluations. Obsevations included videotaping using a floating ca technique along majo and mino ateials in the study aea. Refe to Appendix A fo taffic count data. Tanspotation System Plan Page A- 1

3 Moto Vehicle System The moto vehicle system within the study aea was eviewed as to thei physical and opeational chaacteistics. The following sections pesent: Definition of Functional Class A naative desciption of key outes Steet facility inventoy Taffic Volumes Taffic Contols Level of Sevice Analysis Taffic Collision Analysis Roadway Functional Classification Roadways have two pimay functions; to povide mobility and to povide access. Fom a design pespective, these functions can be pola opposites (see diagam below) since high o continuous speeds ae desiable fo mobility, while low speeds ae moe desiable fo land access. Ateials emphasize a high level of mobility fo though movement; local facilities emphasize the land access function; and collectos offe a balance of both functions. Functional class also can be defined by connectivity. Without connectivity, neithe mobility no access can be seved. Roadways that povide the geatest each of connectivity ae the highest-level facilities. The functional classification system was assumed to be the same as the state designations since the City do not cuently have thei own adopted functional classification system. These function classes will be eassessed though this study, and adjusted, as needed. Figue A-2 epesents ODOT s functional classification of steets in. Any steet not designated as eithe an ateial o collecto is consideed a local steet. Tanspotation System Plan Page A-3

4 Functional Class Definitions Ateial steets inteconnect and suppot the pincipal highway system. These steets link majo commecial, esidential, industial and institutional aeas. Ateial steets ae typically spaced about one mile apat to assue accessibility and educe the incidence of taffic using collectos o local steets in lieu of a well placed ateial steet. Many of these outes connect to City suounding. Thee ae both majo and mino ateial classifications in. Majo ateial steets typically povide moe connectivity and/o cay moe taffic volume than mino ateial steets. Collecto steets povide both access and ciculation within esidential and commecial/industial aeas. Collectos diffe fom ateials in that they povide moe of a citywide ciculation function, do not equie as extensive contol of access and penetate esidential neighbohoods, distibuting tips fom the neighbohood and local steet system. Local Steets have the sole function of poviding access to immediate adjacent land. Sevice to though taffic movement on local steets is delibeately discouaged by design. Desciption of Ateial Routes The following majo outes in ae descibed as to thei functional classification, connectivity and oadway volumes. In all cases, the functional classifications noted ae as designated by ODOT. These classes will be e-evaluated as a pat of this study to detemine appopiate classes fo each of the City. City of (also called Newpot Avenue, 1 st Avenue, Bayshoe Dive and eet) is classified as a Majo Ateial. It is a egional oute poviding access to the est of the coast, both noth and south of. It povides access to ateial and collecto steets within. At the south end of Coos Bay, (known in this aea as Newpot Avenue) is a two-way oadway with wide shouldes and intemittent sidewalks along its fontage. splits to a one-way couplet nothbound at Font Steet (changes names to Bayshoe Dive) and southbound on eet. Highway caies about 24,000 ADT o about 12,000 ADT pe diection in. Coos Rive Highway (Newpot Avenue) is classified as a Mino Ateial. It is a distict level state highway. It is a two-lane, two-way oadway. It caies about 10,000 vehicles daily nea the Isthmus Slough. Coos Rive Highway povides access to aeas to the south and east of. Commecial Avenue is a Majo Ateial that uns east/west though, connecting with westen pats of the City. It is a two-lane steet with sidewalks along its fontage. It caies about 4,000 vehicles daily just west of. Andeson Avenue is a Majo Ateial and was juisdictionally tansfeed to the City. It uns east/west though, connecting with westen pats of the City. It is two-lane, one-way steet with sidewalks along its fontage. Commecial Avenue and Andeson Avenue fom a one-way east-west couplet aound s downtown coe between U.S. 101 and 7 th Steet. Cental Avenue is a Majo Ateial and was juisdictionally tansfeed to the City. It uns east/west though, connecting downtown with westen pats of the City. It is a two lane, twoway steet with no on-steet paking, occasional left tun lanes and sidewalks along its fontage. It has a posted speed of 25 miles pe hou and caies about 13,000 vehicles daily just west of 10 th Steet. Boulevad is a Majo Ateial. It uns nothwest to southeast though, connecting the downtown aea with esidential aeas to the west. It is typically a fou-lane, two-way steet with occasional tun lanes at intesections. Thee ae geneally no bike lanes, but thee ae sidewalks along its fontage. Boulevad caies about 10,000 vehicles daily between LaClai Steet and Woodland Dive. Newmak Avenue is classified by ODOT as a Majo Ateial west of eet. It has been juisdictionally tansfeed to the City. It uns east and west though. Newmak is geneally a Tanspotation System Plan Page A-4

5 fou-lane, two-way oadway between Boadway and Boulevad with sidewalks in some locations. Thee ae stiped shouldes in some locations on the oadway, but thee ae no dedicated bike lanes. Newmak Avenue caies about 14,000 vehicles daily nea LaClai Steet. Boulevad is a Majo Ateial and is a distict level state highway (Cape Aago Highway), but has been juisdictionally tansfeed to the City within City limits. It geneally uns along the ocean on the west side of, connecting to Newmak Avenue. It is a two-lane, two-way facility with shouldes, but no bike lanes o sidewalks. The posted speed is 35 miles pe hou and the oadway caies about 10,000 vehicles daily nea nue. Koosbay Boulevad is a Mino Ateial. It is a two-lane, two-way steet that caies about 7,000 vehicles daily nea Thompson Road. 10 th Steet is a Mino Ateial. It is a two-lane, two-way steet with left tun lanes at some locations, such as Cental Avenue. It caies about 4,000 vehicles daily nea Cental Avenue. Thee ae geneally sidewalks, but no bike lanes. Steet Facility Inventoy Listing The steet facility inventoy fo is summaized in the appendix. This table lists the physical featues of the oadway facilities including: Functional classification accoding to ODOT s designation Paved width (distance between cubs o shouldes, as appopiate) Estimated aveage daily taffic volumes Posted speed limit Povision of pedestian and bicycle facilities The estimated taffic volumes wee calculated by multiplying the p.m. peak hou two-way volume fo a given steet segment by 10 to epesent aveage daily tavel. Whee taffic volume data was not available an enty of N/A is indicated. The steet inventoy data was futhe efined to highlight the potion that povide bicycle and pedestian facilities accoding to functional class. Table A-1 on the next page summaizes the findings. Seveal geneal obsevations wee made: Bike facilities geneally ae not povided on ateials and collecto steets. Oveall, bike lanes ae pesent on 3% of the majo ateials, 10% of the mino ateials, and 0% of collecto steets. Sidewalks geneally ae povided along ateial steets, and geneally ae not povided along most collecto steets. Oveall, sidewalks ae pesent on 41% of the majo ateials, 0% of the mino ateials, and 5% of the collecto steets. Collecto steets typically have 36 feet paved width. Collecto steets geneally cay 1,000 to 4,000 vehicles daily with a maximum listed of 7,000 (4 th Steet in ). Mino ateials steets cay 4,000 to 12,000 vehicles daily.

11 Taffic Levels of Sevice Level of Sevice (LOS) is used as a measue of effectiveness fo intesection opeation. It is simila to a epot cad ating based upon aveage vehicle delay. Level of Sevice A, B, and C indicate conditions whee taffic moves without significant delays ove peiods of peak hou tavel demand. Level of Sevice D and E ae pogessively wose peak hou opeating conditions. Level of Sevice F epesents conditions whee aveage vehicle delay exceeds 80 seconds pe vehicle enteing a signalized intesection and demand has exceeded capacity. This condition is typically evident in long queues and delays. Level of sevice calculations wee based on peak 15-minute volumes 1. Level of sevice D o bette is geneally the accepted standad fo signalized intesections in uban conditions. has not adopted a LOS standad. The appopiate standad will be selected as a pat of this study pocess. In addition, the Oegon Highway Plan sets maximum volume-to-capacity atios (v/c) fo peak hou opeating conditions, based on ODOT s highway classification and othe citeia. Fo statewide feight outes (i.e. US 101 though ), intesections ae equied to opeate at a v/c of 0.75 o bette (fo speeds 45 mph). All othe state facilities in the study aea ae distict level highways, which ae equied to opeate at a v/c of 0.85 o bette (fo speeds 45 mph). Unde existing conditions, these citeia ae met fo all state facilities in the study aea. Intesections Without Taffic Signals The level of sevice assessment fo intesections without taffic signals is significantly diffeent. The epoted LOS applies only to the majo and mino steet tuning movements, and ae not epesentative of majo steet though movements. Fo this eason, LOS E and even LOS F can occu fo a specific tuning movement; howeve, the majoity of taffic may not be delayed (in cases whee majo steet taffic is not equied to stop). LOS E o F conditions at unsignalized intesections geneally povide a basis to study intesections futhe in ode to detemine availability of acceptable gaps, safety and taffic signal waants. A summay of the desciptions fo level of sevice fo signalized and unsignalized intesections is povided in the Level of Sevice Desciptions in the Tanspotation System Plan technical appendix. Intesection tun movement counts wee conducted duing the evening peak peiods to detemine the existing 2002 LOS based on the 2000 Highway Capacity Manual methodology fo signalized and unsignalized intesections 2 (see Appendix fo desciptions). Taffic counts and level of sevice calculation sheets can be found in the appendix. The following sections descibe existing conditions along seveal key coidos in. Tables A-3 and A-4 povide a summay of the PM peak hou levels of sevice fo the study intesections in. Most intesections opeate at LOS D o bette, with some exceptions. A total of 13 signalized intesections and 23 unsignalized intesections wee analyzed within. All of the signalized intesections opeate at LOS C o bette. All but five of the unsignalized intesections opeate at a LOS of C o bette fo the mino steet left tuns. Table A-4 shows the existing intesection levels of sevice within. Additionally, all intesections on state highways opeate at acceptable levels accoding to the OHP v/c standads in. 1 Peak 15-minute volumes wee multiplied by fou, as discussed in the 2000 Highway Capacity Manual, in lieu of using a peak hou facto, to aive at houly volumes equied fo Highway Capacity Manual intesection analysis Highway Capacity Manual, Tanspotation Reseach Boad, Tanspotation System Plan Page A-11

Futhe analysis should be conducted (examination of futhe taffic signal waants) to detemine whethe o not a taffic signal is cuently waanted at one o both of the diveways. None of the othe suveyed intesections without taffic signals met this fist tie waant. ODOT only ecognizes Waant 1 fo peliminay signal waant puposes. This waant is evaluated in the Futue Needs section of this TSP. Othe Taffic Opeational Issues Seveal notes wee made duing field obsevations that add to the technical analysis based above. These issues include: Absence of sepaate left-tun lanes on ateial facilities educes facility capacity (vehicles pe hou) and inhibits taffic safety. A pime example is Highway 101 at East Bay Dive immediately noth of the McCullough Bidge. Othe examples ae on Boulevad and nue. Taffic signal coodination in downtown on Highway 101 should be eviewed. Rolling vehicle queues in the southbound diection wee obseved extending seveal blocks noth of Commecial Avenue. High fequency of diveway cuts along ateials inceases vehicle conflict potential.

16 Collisions Vehicle, pedestian, and bicycle collision data was obtained fom ODOT and used to develop the high collision intesection and segment lists fo the Tanspotation System Plan. Table A-9 shows cash locations within at intesections whee taffic count data was available and whee at least one accident pe yea was epoted. The numbe of collisions within 200 feet of an intesection wee included in the total. Locations appoaching o above a cash ate of 1.00 pe MEV ae consideed significant and should be investigated. The highest ate location in is 2 nd Steet at Ingesoll Avenue is a elatively low volume intesection. The next thee locations, 10 th /Cental, Thompson/Woodland, and Woodland/ each ae ateial intesections with much highe volumes and cash fequencies. The highest numbe of cashes and the highest cash ate intesection in Noth Bend is Newmak Avenue at Boadway. Thee ae some locations that had moe than thee cashes ove the thee-yea peiod, but taffic volume data was not available to calculate a cash ate.

19 Tansit Fedeal funding fo the fixed-oute tansit sevices that did exist in was teminated and sevice ceased opeation as of the end of Decembe The CCTA has applied fo fedeal gants fom the Fedeal Tansit Authoity to extend these basic opeations. Cuently, only the dial-a-ide sevice is opeational. The discussion below is witten assuming that funding and sevice is estoed to pevious levels. Tansit sevice is povided by Coos County Aea Tansit (CCAT). Figue A-8 shows cuent CCAT fixed bus outes and the location of cuent bus stops and sheltes thoughout the study aea Thee ae six coveed sheltes in the tansit system today with the emainde having combinations of benches o posted signs only. Weekday bus boading infomation was epoted by CCAT fo the cuent 2000 census. Table A-12 shows the ideship fo the outes seving ove the past two yeas. The fixed oute loop sevices have gown about 20 pecent and the dial-a-ide sevice has gown almost 50 pecent in the past yea. Table A-13 epots the fequency of sevice fo the vaious fixed oute and expess oute opeations. Diala-ide sevices ae scheduled by appointment on an as needed basis. Note: Since this chapte of the TSP was witten, all fedeal funding fo CCAT has been withdawn.

20 Pote Stage Lines, Geyhound and Coos County Aea Tansit (CCAT) combine to povide the tansit options fo individuals in the / Noth Bend aea. Pote Stage Lines has 7 buses that can cay between 11 and 47 passenges each and povide sevice twice a day to Eugene/Bend/Ontaio. Likewise, Geyhound povides inte-jusidictional connectivity thoough outes that povide access to many aeas of the State including Eugene/Potland/Medfod and othe lage cities in Oegon. The majoity of inta-jusidictional tansit tips ae povided by CCAT, which has ten sevice vehicles (5 in good condition, 4 in fai condition, and 1 in poo condition) that ae all ADA accessible and has annual opeating expenses ove $200,000. Cuently, the sevice is povided on a demand esponsive basis and focuses mainly on the tanspotation disadvantaged population, such as the handicapped, eldely and economically disadvantaged. Two dial a ide buses opeate Monday-Fiday in the /Noth Bend aea, anothe in Coquille and a fouth in Bandon. Appoximately 37,000 tips well be povided system wide this yea, with 15,000 of those tips occuing in /Noth Bend. This does not begin to meet demand, howeve, as ove 90,000 unlinked tips wee povided system wide befoe the fixed oute sevice was discontinued. Since a fixed oute sevice was oiginally opeational in /Noth Bend, much of the infastuctue is still pesent. The City has identified bus stop locations, and signs and sheltes ae in place. The oppotunity fo inceasing tansit modal shae is lage as is shown in both evealed pefeence actions such as the ideship numbes befoe fixed outes wee discontinued, and in stated pefeence assetions such as the opinion suvey pepaed fo the 1995 STIP plan that indicated consideable suppot fo expanded sevice. Additionally some of the capital costs associated with the implementation of oute stat-up have aleady been povided. The lagest obstacle to the povision of fixed oute sevice is the identification of a funding mechanism equied fo opeation costs, as fae box ecovey is expected to be a vey small pecentage of total opeating costs. Bicycle Bicycle counts wee conducted duing the evening peak peiod (4:00 to 6:00 PM) at the study intesections in and ae shown in Figue A-9, along with the existing bike lanes, designated bikeways and offsteet bike pathways. Thee is only one small section of that has designated bike lanes in the entie study aea. Thee ae a numbe of oadways that have paved shouldes that could be used fo bicyclists. A specific inventoy of these wide shoulde locations was not undetaken. A Bikeway Maste Plan fo the Bay Aea and Coos County Paks was completed in As pat of this plan, use pattens wee detemined based on public input. Within the City, bicycle tips ae typically made fo utility puposes between coe aeas such as,, Newmak and othe ateial and collecto steets. Outside the City, tips ae moe eceational in natue. The Oegon Coast Bike Route (OCBR) is the only maked bike oute in the aea. It is a combination of shaed oadway, shoulde and bike lane types. As mentioned peviously, the only designated bike lanes exist on. Due to the lack of bike lanes and spoadic paved shouldes (less than 10 pecent of ateials and collectos have bike facilities), thee is limited connectivity fo bicyclists taveling to activity centes in. Bicycles ae pemitted on all oadways in the both City. Bicycle use in is geneally fo eceational, school and commuting puposes. 4 Bikeway Maste Plan fo Bay Aea and Coos County Paks, Gay L.

23 Pedestians Figue A-10 shows the existing sidewalks on ateial and collecto steets in. A majoity of ateial and collecto steets in have sidewalks on at least one side of the steet. Thee ae some locations whee sidewalks ae not connected; howeve, connectivity and pedestian linkages ae elatively good. In addition, besides the facilities that ae shown on this map, many esidential steets also have sidewalks. Pedestian counts wee conducted in conjunction with the intesection PM peak tun movement counts. The pedestian movement counts ae also shown in Figue A-10. The most significant pedestian volumes in the aea ae in the city s espective downtown s and nea the Southwest Oegon Community College, which ae lage pedestian geneatos. The most significant pedestian movements occu in the downtown aea on Boadway, Commecial and Elod Avenue and in the Noth Bend downtown aea on nue at Sheman Avenue. The intesection of Newmak Avenue at LaClai Steet in had the single highest one-hou pedestian volume, 108 pesons. Based on the steet inventoy, most majo ateials facilities have sidewalks (84%) while mino ateial and collecto steets have vey limited existing sidewalk facilities (less than 10%) Sidewalks at least five feet wide ae equied in all new development. All newly constucted sidewalks include wheelchai amps at intesections to pemit easy ingess/egess fo wheelchais. The most impotant needs ae to fill in the gaps on the ateial system such as on Newmak Avenue and Bayshoe Dive. Howeve, the City of should wok to continue inceasing the sidewalk coveage on all ateials, collectos, and esidential steets in the aea. Paking Downtown paking studies wee conducted in both in Existing on-steet paking locations fo both City ae shown in Figue A-11 fo ateial and collecto steets. In, seveal pakingelated issues wee identified though the public involvement pocess and included the following: Convenient paking is difficult to find Some off-steet paking lots ae peceived as unsafe at night On-steet paking isn t eadily available fo patons and visitos to downtown Paking system is confusing Abuses of on-steet paking supply limits custome access Meetings, stakeholde suveys and public open houses wee conducted to detemine the key issues in the paking situation in downtown. The following was concluded: Most paking (both on and off-steet) is undeutilized in the peak hou (based on paking suveys conducted by both the City and the Consultant) Thee is a sense that the paking system is not easily undestood o convenient Thee ae complaints that 1 hou metes (o contolled aeas) ae not sufficient to suppot shot tem access equiements. An inventoy was taken to detemine the elationship between supply and demand. Oveall utilization was detemined to be about 44 pecent of the available supply. This does not indicate an existing paking supply deficiency. In Noth Bend, paking inventoy and demand studies wee conducted. Thee wee a total of 1,633 paking spaces in the downtown aea (including 597 on-steet spaces and 1,036 off-steet spaces). 5 City of Downtown Paking and Ciculation Study, Kittelson & Associates, Inc., Septembe City of Noth Bend Downtown Paking Study, David Evans and Associates, Inc., Decembe Tanspotation System Plan Page A-23

24 Paking occupancies wee obseved fo thee weekday time peiods (7-9 AM, 11:30 AM-1:30 PM and A- 5 PM) and on Satuday fom 12:00-1:30 PM. The occupancy suveys wee conducted in Apil, which may be lowe than in the summe, which is peak season along the coast. Accoding to ODOT taffic counts, aveage daily taffic (ADT) in Apil epesents about 94% of nomal. Occupancies anged fom about 28 pecent occupancy on Satuday to 45 pecent occupancy in the weekday evening peak peiod. This does not indicate an oveall paking deficiency. The above occupancy suvey findings contast shaply with opinions expessed by the geneal public and local mechants egading the availability of paking. The quantitative studies do not suppot the epoted view that paking is limited. It is appaent that the paking suveys identified available paking outside of the walking distance many of the patons o mechants desie. A moe focused assessment that sepaated paking availability elative to anges of walking distances may be moe evealing. Tucks The tuck (heavy vehicle) volumes as well as pecentages as a potion of though taffic at the study intesections wee collected with the cuent tun movement counts. The cuent tuck pecentages, which ange fom 0 to 9 pecent, ae shown on Figue A-12. though is the only designated feight oute in the study aea 6. Existing though tuck outes and intemodal connectos ae also shown in Figue A-12. The 1999 Oegon Highway Plan designates a State Highway Feight System. The OHP can be found at A map of the State Highway Feight System can be viewed at The State Highway Feight System is based on feight volume, connectivity and linkages to majo intemodal facilities. though is designated as pat of the State Highway Feight System. Effots to impove tuck feight mobility and capacity within the planning aea should fist focus on the oadways compising the local feight system. Othe tuck feight concens that should be investigated ae lack of tuning lanes, naow lanes, naow shouldes, difficulties in accessing business sites, tuning adii at intesections o bidges with weight o height concens. Some feight-elated povisions in the Highway Plan include policies and actions elating to access fom highways to adjacent popeties. The Highway Plan s discussion of access management is intended to balance access to developed popeties while ensuing the safe and efficient movement of though taffic and local taffic. The plan identifies a ange of policies, actions, and standads petaining to intechange development, diveway and oadway spacing and design, taffic signal location, median design and spacing of openings, and othe factos associated with managing access along vaious types of uban and ual highways. Managing access includes poviding fo though tuck movements as well as fo the pick up and delivey of goods and mateials to and fom adjacent Oegon Highway Plan, The Oegon Depatment of Tanspotation, Appendix D: Highway Classification by Milepoint.

28 commecial and industial popeties. The oadway system includes seveal intemodal connectos. An intemodal connecto is a oad connecting an intemodal feight o passenge facility though which goods o people move between modes. Some intemodal connectos ae pat of the National Highway System (NHS). Intemodal feight movements, fo example, involve the movement of goods and mateials by oad, ail, wate, ai, and pipeline though tuck-ail facilities, maine teminals, aipots, and pipeline teminals. Most intemodal connectos ae local oads, not state highways. Intemodal connectos in seve pimaily maine facilities and ae shown in Figue A-12. The pupose of this section of the TSP is to identify the majo outes (and shippes) associated with the movement of feight by tuck in. A few of the concens and needs about maintaining and enhancing cuent tuck feight mobility ae also mentioned. Some of the moto vehicle needs identified in the TSP will also impove tuck feight mobility. As in othe cities, feight moves pimaily by tucks in the aea. Tuck tacto-taile combinations ae the most common type of feight caie and move the geatest vaiety of goods and commodities, anging fom low-value bulk commodities to high-value, time-sensitive commodities. The majo commodities moved by tuck in ae wood chips, logs, plywood, paticle boad, petoleum poducts, seafood and geneal mechandise. Tucks, along with intecity buses, have the geatest locational mobility among feight modes in that they can go, subject to size and weight limitations, wheeve oads go. The closest ODOT ATR (automatic taffic ecode) is located appoximately 5 miles south of Coos Bay on (mp ). In 2002, the aveage daily taffic (ADT) was appoximately 15,000 vehicles, with 16 pecent tuck taffic. This equates to appoximately 2,400 tucks pe day. Pecent tuck taffic is highe on state highways in the ual aeas because thee ae less cas thee then in the uban aeas. Many of the tucks using these intesections ae going to o coming fom local industies and pot facilities located in nea the and the Isthmus Slough. These industies and facilities include the Oegon Chip Teminal, Tyee Oil, Dedicated Fuels Inc. and the Pot of. Seveal industies ae located southeast of in the Bunke Hill (Coos County) aea and account fo some of the tuck taffic at the /Coos Rive Highway intesection and othe US 101 intesections. They include the Geogia-Pacific Chip Teminal, Docks, Coastal Fibe, Coos Head Timbe and a Geogia Pacific Sawmill. Some of the tuck taffic is also geneated by the commecial businesses in the /Noth Bend aea such as Wal-Mat, Bi-Mat, K-Mat and the lage chain gocey stoes. In ode to bette handle tuck taffic, some intesections on in need to be impoved. Some of the intesection cub adii ae too shap to accommodate the tuning movements of the lage tucks (especially ight tuns). Fo example, tucks heading south on in Noth Bend wanting to tun west on to nue (Cape Aago Highway) must swing out into the othe tavel lane. This poblem is also pesent at othe intesections on such as Commecial/ and Califonia Ave/. These movements ae unsafe fo othe moto vehicles and educe the capacity of the oadways. The /Coos Rive Highway intesection is a bottleneck because of its tiangula configuation and poximity to othe busy intesections in the immediate aea.
