Residential street design standards that are illustrated in Table 3-2. Because the designation of standard residential streets is adequately set forth in the City ’s Land Development Code (and is dependent upon the number of dwelling units proposed in a land developm ent application that will be served by the street), illustration of proposed standard residential streets in the TSP is not appropriate. Accordingly , these streets are not reflected in Figure 5-2. Existing sta ndard residential streets are illustrated in Figure 3-1. Access Management The term access m anagem ent refers to the process of balancing the need for access to parcels of land adjacent to roadway s with the need for safe and efficient through m ovem ent of vehicular traffic on the roadway . Access m anagem ent can be im plem ented by a variety of m eans. These include m edian controls (e.g., raised concrete m edians), driveway spacing and/ or driveway consolidation (so that there are fewer driveway s serving one parcel or m ultiple parcels), requiring that driveway s be placed on lower order streets where a parcel abuts both higher and lower order streets, and intersection spacing to reduce the number of conflict points or signal-controlled locati ons along a street as the frequency of these locations can reduce the benefits of effective signal tim ing progression. Access m anagem ent is closely related to street func tional classification. Ty pically , when access controls are in place, the frequency of driveway s and intersecting streets is m ore restrictive along state highway s and major arterials where the movem ent of traffic takes a higher priority . Access controls are less restrictive along collector streets where there is greater balance between access and m obility . Access controls are restricted only by safety considerations along local streets where property access is the prim ary function of the street. As indicated in the 2001-2023 Rogue Valley Regional Transportation Plan’s discussion of roadway access guidelines “access management is an important key to balanced urban growth.” Lack of prudent access control standards results in loss of transpor tation capacity , a poor environm ent for alternative modes of travel, and reduced safety . Frequent driveway and cross-street access can significantly degrade traffic operations along m ajor streets as m otorists m ust contend with people slowing to turn into adjacent property or attem pting to get back onto the m ajor street from a side access location. Not only do frequent driveway s adversely affect the operational capacity of a road, they also affect saf ety in that each driveway or intersecting street represents a potential conflict point for through-m oving vehicles. The strip developm ent that often occurs as a result of the lack of access control can also be inhospitable to pedestrians and can be difficult to adequately serve by transit due to the spread out nature of destinations. Access m anagem ent can be m ost effectively implem ented during the land developm ent process when access locations and localized street im provem ents can be adapted to ensure that adjacent street traffic- carry ing functions are not degraded. Access m anagem ent controls are m ore difficult to implem ent along streets with developed property due to possible right -of-way limitations and/or the concerns of property owners about business or on-site circulation im pacts. In these cases, access controls can be incorporated into a roadway improvem ent project. Strategies for Access Management Along State Highways Along state highway s, access is com monly controlled by the Oregon Departm ent of Transportation (ODOT) through the purchase of access rights. New access to/from a state highway is provided consistent with the standards adopted in the Ore gon Highway Plan for each highway classification, its location within an urban or rural area, and its posted speed. Access m anagem ent guidelines for the state highway s within the Medford UGB are shown in Table 5-7. These highway s include I-5, Highway 99 north of McAndrews Road and south of Ba rnett Road, Highway 62, and Highway 238. Medford Transportation Syst em Plan 5-24 Street Plan
