What Is the Difference Between an Arterial Street and a Non-Arterial (Local) Street?
WHAT IS THE DIFFERENCE BETWEEN AN ARTERIAL STREET AND A NON-ARTERIAL (LOCAL) STREET? Federal and State guidelines require that streets be classified based on function. Generally, streets are classified as either arterial streets or non-arterial streets. Cities can also use the designations to guide the nature of improvements on certain roadways, such as sidewalks or street calming devices. The primary function of arterials is to provide a high degree of vehicular mobility through effective street design and by limiting property access. The vehicles on arterials are often through traffic. Generally, the higher the classification of a street (Principal Arterial) being the highest), the greater the volumes, through movements, length of trips and the fewer the access points. Arterials in Shoreline are further divided into the three classes and are described as follows: • Principal Arterials have higher levels of local land access controls, with limited driveway access, and regional significance as major vehicular travel routes that connect between cities within a metropolitan area. Examples: Aurora Avenue N, NE 175th Street and 15th Avenue NE • Minor Arterials are generally designed to provide a high degree of intra-community connections and are less significant from a perspective of a regional mobility. Examples: Meridian Avenue N,N/ NE 185th Street and NW Richmond Beach Road • Collector Arterials assemble traffic from the interior of an area/community and deliver it to the closest Minor or Principal Arterials. Collector Arterials provide for both mobility and access to property and are designed to fulfill both functions. Examples: Greenwood Avenue N, Fremont Avenue N and NW Innis Arden Way. -

Petition For/Request to Initiate Vacation of Public Highway, Street, Alley Or Easement Requirements and Process Overview
Petition for/request to initiate vacation of public highway, street, alley or easement Requirements and process overview The City of St. Louis Park will vacate public highways, streets, alleys or easements if it is found that the city has no current or future need for these lands. Proceedings to vacate such land may be commenced by petition of a majority of the owners of property fronting upon the portion of the public highway, street, alley or easement to be vacated, by action of the St. Louis Park City Council or by recommendation of the St. Louis Park Planning Commission. In order to constitute a petition for vacation, a majority of abutting property owners of the portion of public highway or street to be vacated must appear on the petition form. If the request is for vacation of a public alley or easement, it must be signed by the majority of owners of property adjacent to the alley or easement in the block where the alley or easement is situated, whether or not the petition requests vacation of the entire alley or easement. The petition shall be filed with the city clerk. If the application represents a request to the planning commission to recommend and to the city council to initiate vacation, that must be specifically stated. The applicant is encouraged to discuss the proposal with community development staff prior to completion of final plans and filing of a petition/request.

Mr. Gupta Detailed the Current Status of India's Road Network and Its
Mr. Gupta detailed the current status of India’s road network and its maintenance: “The total length of the road network in India is 4.69 million km. It is the second largest road network in the world, just after the United States. ….. The national highways constitute 82,000 kilometers, 1.7 percent of the total length, and carry 40 percent of the total traffic.” “65 percent of total traffic and 90 percent of passenger traffic are being serviced by roads. The corresponding figures in the 1950s were 12 percent and 31.6 percent. The compounded annual growth rate of traffic on roads during the last two decades has been 9 percent. Road maintenance, however, is not commensurate with the traffic growth rate.” “The Indian Constitution assigns responsibility for the national highway network to the central government while State governments are responsible for developing and maintaining the state highways, major district roads, other district roads, and village roads. ….. The Ministry of Road Transport & Highways is the apex organization in the road sector in the country responsible for the planning, development, and maintenance of the national highways. It extends technical and financial support to state governments for the development of state roads, the connectivity of roads of interest and economic importance; it evolves the standards and specifications for roads and bridges in the country.” “Several road development programs are being implemented in the country. The first, the National Highway Development Program, is one of the world's largest road development programs. It comprises seven phases of development of more than 55,000 km of national highways; of which 21,000 km of road length has already been completed.” “Another is the Rural Road Development Program fully funded by the central government to supplement the efforts of the state governments in the construction and maintenance of the rural road network. -

Safety Rest Areas and the American Travel Experience
Balancing Past and Present Safety Rest Areas and the American Travel Experience Joanna Dowling, MSHP National Safety Rest Area Conference 2008 I have been researching rest area history and architecture for the past three years now, and one of the things that I have learned in that time, is that if you are going to study bathroom history you have to have a sense of humor about it, so I am going to attempt to make this discussion as lively as possible. My primary focus has been looking at the developmental history of the rest area program, beginning with the Federal Aid Highway Act of 1956 through the 1970s. And also looking at the architectural forms that were built in these sites; this is based on a background in historic preservation and architectural history. I presented at two conferences in Albuquerque last month, The Society for Commercial Archeology and Preserving the Historic Road, and people were very interested in this topic, which I hope will be encouraging to all of you. Today, I want to talk about the more functional aspect of this story. In keeping with the theme of the conference “More with Less,” the premise of my talk is “balancing past and present.” because I think that there are many mutually beneficial solutions to be found in the combined awareness of history and function. 1 Designed to be both functional and aesthetically pleasing, the rest areas at most locations will include lighted rest-room facilities, a few picnic tables and benches, parking, on-and-off ramps, a water fountain, litter barrels, a telephone booth and a travel information shelf. -
