The HDM-4 provides a deterministic approach in data input and process data of existing road condition, traffic volume and pavement composition to predict road deterioration as per the urban road conditions in terms of International Roughness Index (IRI) value. This study presents the use of HDM-4 model for the computation of optimum Maintenance and Rehabilitation (M&R) strategy for each road section and comparative study of scheduled and condition responsive M&R strategies. The results of present study will be useful for gaining better support for decision-makers for adequate and timely fund allocations for preservation of the urban road network. Keywords: Pavement, management, maintenance, HDM-4, urban road, predict, road deterioration. 1. Introduction Construction of road network involves substantial investment and therefore proper maintenance of these assets is of paramount importance. It is found that the actual available maintenance expenditure amount is much less than what is required for urban roads. -

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. -

What Are the Advantages of Roundabouts?
What is a roundabout? A roundabout is an intersection where traffic travels around a Circulatory central island in a counter- Truck Apron Roadway clockwise direction. Vehicles entering or exiting the roundabout must yield to vehicles, bicyclists, and pedestrians. Figure 1 presents the elements of a roundabout. Yield Line Splitter Island Figure 1: Elements of a Roundabout What are the advantages of roundabouts? • Less Traffic Conflict: Figure 2 compares the conflict points between a conventional intersection and a modern roundabout. The lower number of conflict points translates to less potential for accidents. • Greater safety(1): Primarily achieved by slower speeds and elimination of left turns. Design elements of the roundabouts cause drivers to reduce their speeds. • Efficient traffic flow: Up to 50% increase in traffic capacity • Reduced Pollution and fuel usage: Less stops, shorter queues and no left turn storage. • Money saved: No signal equipment to install or maintain, plus savings in electricity use. • Community benefits: Traffic calming and enhanced aesthetics by landscaping. (1) Statistics published by the U.S. Dept. of transportation, Federal Highway Administration shows roundabouts to have the following advantages over conventional intersections: • 90% reduction in fatalities • 76% reduction in injuries • 35% reduction in pedestrian accidents. Signalized Intersection Roundabout Figure 2: Conflict Point Comparison How to Use a Roundabout Driving a car • Slow down as you approach the intersection. • Yield to pedestrians and bicyclists crossing the roadway. • Watch for signs and pavement markings. • Enter the roundabout if gap in traffic is sufficient. • Drive in a counter-clockwise direction around the roundabout until you reach your exit. Do not stop or pass other vehicles. -

2021 LIMITED ACCESS STATE NUMBERED HIGHWAYS As of December 31, 2020
2021 LIMITED ACCESS STATE NUMBERED HIGHWAYS As of December 31, 2020 CONNECTICUT DEPARTMENT OF Transportation BUREAU OF POLICY AND PLANNING Office of Roadway Information Systems Roadway INVENTORY SECTION INTRODUCTION Each year, the Roadway Inventory Section within the Office of Roadway Information Systems produces this document entitled "Limited Access - State Numbered Highways," which lists all the limited access state highways in Connecticut. Limited access highways are defined as those that the Commissioner, with the advice and consent of the Governor and the Attorney General, designates as limited access highways to allow access only at highway intersections or designated points. This is provided by Section 13b-27 of the Connecticut General Statutes. This document is distributed within the Department of Transportation and the Division Office of the Federal Highway Administration for information and use. The primary purpose to produce this document is to provide a certified copy to the Office of the State Traffic Administration (OSTA). The OSTA utilizes this annual listing to comply with Section 14-298 of the Connecticut General Statutes. This statute, among other directives, requires the OSTA to publish annually a list of limited access highways. In compliance with this statute, each year the OSTA publishes the listing on the Department of Transportation’s website (http://www.ct.gov/dot/osta). The following is a complete listing of all state numbered limited access highways in Connecticut and includes copies of Connecticut General Statute Section 13b-27 (Limited Access Highways) and Section 14-298 (Office of the State Traffic Administration). It should be noted that only those highways having a State Route Number, State Road Number, Interstate Route Number or United States Route Number are listed. -
The Permanence of Limited Access Highways*
The Permanence of Limited Access Highways* Adolf D. M ay, Jr. Assistant Professor of Civil Engineering Clarkson College of Technology Potsdam, N. Y. Almost all studies of urban and state highway needs point out that in general streets and highways are not adequate for present traffic. Furthermore, these studies indicate that future traffic will have greater demands, and unless more action is taken, the highways will deteriorate, structurally and geometrically, at a rate faster than they can be replaced. The American way of life is dependent upon highways, as ex emplified by the rapid development of commercial, industrial, and residential areas along a new highway. In certain cases, this land development has occurred before the highway was opened to traffic. In the development of a new high-type highway, design features are controlled to permit optimum safe speeds, but as soon as some highways are open there is so much of a conflict between the high speed of through traffic and the variable speed of local traffic that control of speed is often a necessity. Soon afterwards, slow signs, blinking lights, and finally stop signs and traffic lights become necessary, thus decreasing the effectiveness in the movement of through traffic. Then it is usually too late and too expensive to rehabilitate the geometric design of the route, and the usual procedure is to leave the existing route to serve adjacent property and to build a new route for the through traffic. However, without protection of the new route from the development of the adjacent property, the strangulation will occur again and the highway, particularly near urban areas, will again become geometrically inadequate for the intended purpose. -
