Evaluation of Dynamic Speed Feedback Signs on Curves: A National Demonstration ProjectThis report discusses treatments that can potentially reduce speeds and speeding-related crash risks on rural horizontal curves. This report describes the effectiveness of dynamic signs that alert drivers to changes in roadway conditions and that provide those drivers with recommended speeds to safely negotiate a curve. The effectiveness of these signs were determined based on field analysis in 22 locations.
Speed Management: A Manual for Local Rural Road OwnersThis document provides information on how to develop a Speed Management Program that is tailored to meet the needs of local rural road practitioners. A Speed Management Program can be effective in lowering the number of speeding crashes and the resulting fatalities and serious injuries on local rural roads. This document describes the various elements of a Speed Management Program, including the principles of setting speed limits appropriate for roads within the jurisdiction and various countermeasures that are effective in mitigating speeding as it relates to roadway safety in rural areas.
Analysis of Speeding-Related CrashesSpeeding is one of the most common contributing factors of traffic crashes. Data extracted from the Fatality Analysis Reporting System (FARS) show that the driver-level attribute "driving too fast for conditions or in excess of posted speed limit" is the critical contributing factor in more than 99 percent of all speeding-related fatal crashes, as defined by the National Highway Traffic Safety Administration (NHTSA). A marginal number of drivers were determined to be speeding through citations of speeding violations reported to FARS.

Guidelines for the Use of Variable Speed Limit Systems in Wet WeatherThis report provides guidance on the use of variable speed limit (VSL) systems in wet weather at locations where the operating speed exceeds the design speed and the stopping distance exceeds the available sight distance.
Manual on Uniform Traffic Control Devices (MUTCD)The Manual on Uniform Traffic Control Devices (MUTCD) is the national standard for signing on all highways. Sections 2B.13-16 address regulatory speed limits and Section 2C addresses advisory speed signs. School zone speed limit signs are discussed in Section 7B.11 and work zone speed limits in Section 6C.
Methods and Practices for Setting Speed Limits: An Informational ReportThis informational report describes four primary practices and methodologies that are used in establishing speed limits (engineering approach, expert systems, optimization, and injury minimization). It also reviews the basic legalities of speed limits and presents several case studies for setting speed limits on a variety of roads.
Procedures for Setting Advisory Speeds on CurvesThe procedures described in the handbook are intended to improve consistency in advisory speed signing and, hopefully, driver compliance with the advisory speed. The handbook describes; 1) guidelines for determining when an advisory speed is needed; 2) criteria for identifying the appropriate advisory speed; 3) an engineering study method for determining the advisory speed; and 4) guidelines for selecting other curve related traffic control devices.
Speed Management Digital LibraryA collection of resources dealing with speed management. These resources come from a variety of sources and cover many aspects of speed management. [Publication FHWA-SA-14-033]
The Effect of Increased Speed Limits in the Post-NMSL Era, a Report to Congress, 1998. [PDF 407 KB]Section 347 of the NHS Act required the Secretary of Transportation to study the impact of states' actions to raise speed limits above 55/65 MPH and report to the Congress by September 30, 1997.
Two new anti ballistic missiles that can intercept IRBMs are being developed. These high speed missiles (AD-1 and AD-2) are being developed to intercept ballistic missiles with a range of around 5,000 km (3,100 mi).[17] The test trials of these two systems were expected to take place in 2011.[18] The new missile will be similar to the Terminal High Altitude Area Defense (THAAD) missile deployed by US. These missiles will travel at hypersonic speeds and will require radars with scan capability of over 1,500 km (930 mi) to successfully intercept the target.[19]On 6 May 2012, Dr. V. K. Saraswat while confirming the completion of Phase-I added that Phase-II would be completed by 2016 to protect against missiles having range up to 5,000 km.[20]
The MCC is the software intensive component of the ballistic missile defence system. It receives information from various sources such as radars and satellites which is then processed by ten computers which run simultaneously. The MCC is connected to all other elements of the defence through a WAN. MCC performs target classification, target assignment and kill assessment. It also acts as a decision support system for the commander. It can also decide the number of interceptors required for the target for an assured kill probability.[11] After performing all these functions, the MCC assigns the target to the LCC of a launch battery. The LCC starts computing the time to launch the interceptor based upon information received from a radar based on the speed, altitude and flight path of the target. LCC prepares the missile for launch in real time and carries out ground guidance computation.[11]
The Prithvi Air Defence (PAD) is an anti-ballistic missile developed to intercept incoming ballistic missiles outside the atmosphere (exo-atmospheric). Based on the Prithvi missile, PAD is a two-stage missile with a maximum interception altitude of 80 km (50 mi). The first stage is a Solid fuelled motor while the second stage is Liquid fuelled.[11][31] It has manoeuvre thrusters which can generate a lateral acceleration of more than 5 gs at 50 km (31 mi) altitude. Guidance is provided by an internal navigation system with mid-course updates from LRTR and active radar homing in the terminal phase.[11] PAD has capability to engage the 3,000 km (1,900 mi) class of ballistic missiles at a speed of Mach 5.[11] PAD is fast enough to hit medium-range ballistic missiles and intermediate-range ballistic missiles.
On 6 March 2011 DRDO successfully test-fired interceptor missile from Advanced Air Defence (AAD) which destroyed a 'hostile' target ballistic missile, a modified Prithvi, at an altitude of 16 km over the Bay of Bengal. Advanced Air Defence (AAD) missile positioned at Wheeler Island, about 70 km across sea from Chandipur, received signals from tracking radars installed along the coastline and travelled through the sky at a speed of 4.5 Mach to destroy it.[35]
The sequence of events of the test was as follows. At 11 am the Prithvi (missile) lifted off from Launch Complex III at the Integrated Test Range (ITR) at Chandipur, Odisha. Radars at Konark, Paradip detected the missile and were continuously tracking it. The target information was sent to MCC for further processing. MCC classified the target, calculated the trajectory of the missile and assigned the target to a AAD battery located on Abdul Kalam Island (Wheeler Island), 70 km (43 mi) across the sea from Chandipur. The AAD was launched when the Prithvi reached an apogee of 110 km (68 mi). The AAD with the help of midcourse updates and its terminal seeker manoeuvres itself towards the target. AAD makes a direct hit at an altitude of 15 km (9.3 mi) and at a speed of Mach 4. Radars detected formation of a large number of tracks, signifying that the target had broken into multiple pieces. The thermal cameras located on Wheeler Island also picked up the direct hit through thermal images.[14]
On 6 March 2011, India launched its indigenously developed interceptor missile from the Odisha coast. India successfully test-fired its interceptor missile which destroyed a 'hostile' target ballistic missile, a modified Prithvi, at an altitude of 16 km over the Bay of Bengal. The interceptor, Advanced Air Defence (AAD) missile positioned at Wheeler Island, about 70 km across sea from Chandipur, received signals from tracking radars installed along the coastline and travelled through the sky at a speed of 5 Mach to destroy it. As the trial was aimed at achieving the desired result with precision, the interceptor missile had its own mobile launcher, secure data link for interception, independent tracking and homing capabilities and sophisticated radars.
On 22 November 2015 an upgraded version of AAD (Advanced Air Defence) was successfully tested. The anti-ballistic missile took off at 9.40 a.m. from the A.P.J. Abdul Kalam (Wheeler) Island soon after it received the command to waylay and destroy an incoming electronically simulated target missile. Conditions similar to the launch of a target missile from Balasore were simulated electronically and upon receiving its coordinates, the interceptor missile, travelling at supersonic speed, engaged and destroyed the "virtual target" in mid-flight.[48] 2ff7e9595c
