21、tions, and utility networks are growing in complexity. Such networks include highways, railways, and waterways at the surface; subways, pipelines, and cables below the surface; - communication lines and transmission lines above the surface; and wireless communication systems. The possibility of two
22、or more networks occupying a common right-of-way or intersecting increases as the networks grow. As a result, problems arise due to the construction, maintenance, and operations of one network affecting the others. Each transportation agency has the responsibility to maintain highway right-of-way un
23、der its jurisdiction and to preserve the operational safety, integrity, and function of the highway facility. Since the manner in which utilities cross or otherwise occupy highway right-of-way can materially affect the safe operation, maintenance, and appearance of the highway, it is necessary that
24、such use and occupancy be authorized and reasonably regulated. Transportation agencies have various degrees of authority to regulate the use of utilities within highway rights-of-way generally through their authority to designate and to control the use made of right-of-way acquired for public highwa
25、y purposes. Their authority depends upon Federal laws and regulations; and state laws or regulations that differ between states. Also, a state may have local, city, or county government laws and regulations differing from those applicable statewide. Aside from the necessary differences imposed by st
26、ate and local laws, regulations, franchises, governmentalindustry codes, climate, and geography, reasonable uniformity in the engineering requirements should be employed by transportation agencies to regulate the use of highway right-of-way by utilities. Utilities have various degrees of authority t
27、o install their lines and facilities on the right-of-way of public roads and streets. Like transportation agencies, their authorities depend upon state laws and regulations, which differ between states. Utilities also depend upon franchises, local laws, and ordinances, which may differ in the severa
28、l political subdivisions within a state. It is in the public interest for utility facilities to be accommodated on highway right-of-way when such use and occupancy do not adversely affect highway safety, construction, maintenance, or operations. In this respect, guidelines outlining safe and rationa
29、l practices for accommodating utilities within highway right-of-way are of valuable assistance to the transportation agencies. The guidelines herein are provided in the interest of developing and preserving safe highway operations and roadsides. These guidelines make no reference to the legal right
30、of utilities to use or occupy highway right-of-way or to the financial responsibility involved in the adjustment or installation of utilities on such right-of- way. State law governs these matters. These guidelines should be interpreted and applied to the extent consistent with state laws, which giv
31、e utilities the right to use or occupy highway right-of-way. It is the intent of these guidelines to assist the various transportation agencies in establishing and administering reasonably uniform utility accommodation policies. Minimizing possible interference and impairment to the highway and its
32、structures, minimizing adverse visual impacts, and minimizing maintenance are covered in these guidelines. Wherever appropriate, existing utility accommodation policies should be updated in light of these guidelines. 1 A Guide for Accommodating Utilities Within Highway Right-of-way APPLICABILITY The
33、se guidelines apply to all public and private utilities, including, but not limited to, electric power, communications, cable television, water, gas, oil, slurry, petroleum products, steam, sanitary sewers, drainage, irrigation, and similar facilities that are to be located, adjusted, or relocated w
34、ithin the right-of- way of highways under the jurisdiction of transportation agencies. Such utilities may involve underground, surface, or overhead facilities, either singularly or in combination. These guidelines do not apply to the public-private partnerships for the installation and shared use of
35、 fiber optic cable on freeways (Shared Resource Projects). Information on the implementation, planning, design, and construction of Shared Resource Projects is contained in AASHTO Guidance on Sharing Freeway and Highway Rights-of- Way for Telecommunications (1). SCOPE These guidelines are provided f
36、or consideration and use by transportation agencies in regulating the use and occupancy of highway right-of-way by utilities. They are limited to matters, which are the responsibility of transportation agencies for preserving the safe operation, maintenance, construction, and integrity of the highwa
37、y. Where the laws or orders of public authority, industry, or governmental codes, or transportation agencies prescribe a higher degree of protection than provided by these guidelines, the higher degree of protection shall prevail. These guidelines supplement, but do not alter the provisions of the A
38、ASHTO A Policy on the Accommodation of Utilities within Freeway Right-of- Way (2). It is recognized that a distinction exists between buried fiber optic cables and other utilities. These guidelines supplement, but do not alter the provisions of AASHTO Guidance on Sharing Freeway and Highway Rights-o
39、f- Way for Telecommunications (1). DEFINITIONS OF TERMS The terminology used in utility guidelines and policies should depart as little as practical from conventional usage. However, there is a need for some terms having restricted or special meaning. The definitions used in this guide are in the Gl
40、ossary. It is suggested that these definitions be used universally. GENERAL CONSIDERATIONS SAFETY o Highway safety is important when accommodating utility facilities within highway right-of-way. Utility accommodation should not adversely affect highway constructibility, operations, maintenance, and
41、safety. o The design, location, and manner in which utilities use and occupy highway right-of-way shall conform to the policies of the transportation agency to provide and maintain a clear zone. o All permits for utility work should include provisions for the maintenance and protection of the travel
42、ing public, as well as provide a safe workspace for the utility workers. o The transportation agency and the utility procedures should provide for emergency maintenance operations. 2 A Guide for Accommodating Utilities Within Highway Right-of- Way DESIGN Highway and utility facilities, by tradition,
43、 practice, and, in some instances, laws, frequently co-exist within the same corridors. Therefore, it is essential that these public service facilities be compatibly designed and operated. Joint highway and utility planning and development efforts are encouraged. The potential impact on the highway
44、and its use shall be considered in the design and location of utility facilities within the highway corridor. Likewise, the impact of a new or reconstructed highway or street on existing utility facilities should be considered in an attempt to avoid utility relocations. The utility shall be responsi
45、ble to ensure that their facility is properly designed, installed, operated, and maintained including depth, clearances, and separation between lines, and the work is in accordance with the transportation agencys utility accommodation policy. The transportation agency should be responsible for revie
46、w and approval of the utilitys proposal in accordance with the agencys utility accommodation policy. Underground utilities should be accurately located using the American Society of Civil Engineers Standard Guidelines for the Collection and Depiction of Existing Subsuace Utility Data (3) where the e
47、xact location of underground utility infrastructure is required. The survey information should be developed early in the design process so that the designer can show on the plans the accurate location of underground utilities that could cause injuries and property damage. LOCATION New utility lines
48、should be located to minimize the need for later adjustment to accommodate future highway improvements and to permit servicing such lines with minimum interference to highway traffic. New longitudinal utility installations should be located on a uniform alignment as near as practicable to the right-
49、of-way line and outside the clear zone. Longitudinal utility installations on urban streets with closely abutting improvements may require variances to the recommended location on the highway right-of-way and consideration of alternate techniques conducive to safe traffic movement that are permitted by government and industry codes. Such installations shall be resolved in a manner consistent with the prevailing limitations and conditions. The location of utility facilities and appurtenances shall be in accordance with the Americans With Disabili
