Using adaptive traffic management systems that thrive of the massive amounts of data Google collects, Sense could become a digital traffic officer, deploying tech-enabled signals to give the elderly or mobility-impaired citizens longer to cross the street when traffic is busy, and reducing speed limits when pedestrian traffic may be at its highest, like during the school run or at lunchtime.

The Learjet 25 utilize wheel brakes as the primary method for reducing speed after landing. The brake system utilizes hydraulic pressure for power boost. The brake valves are controlled via the rudder pedal toe brakes through mechanical linkages. Two shuttle valves in the pressure lines prevent fluid feedback between the pilot's and copilot's pedals.

General flying ability was positive. The maximum climbing rate was up to reducing speed by per above this mark. In stability terms, the aircraft was stable "directionally" and "laterally" but slightly unstable longitudinally, except at high speed, when it was just stable. Aileron control was light and effective up to maximum speed, but at very low speed response was sluggish, particularly when carrying ordnance.

Roadside habitat modifications could also successfully decrease the number of collisions along roadways. An essential procedure in understanding factors resulting in accidents is to quantify risks, which involves the driver's behavior in terms of safe speed and ability to observe the deer. They suggest reducing speed limits during the winter months when deer density is exceptionally high would likely reduce deer-vehicle collisions, but this may be an impractical solution.

Yaw increases the speed of the outboard wing whilst reducing speed of the inboard one, causing a rolling moment to the inboard side. The contribution of the fin normally supports this inward rolling effect unless offset by anhedral stabilizer above the roll axis (or dihedral below the roll axis). :::L_p Rolling moment due to roll rate. Roll creates counter rotational forces on both starboard and port wings whilst also generating such forces at the empennage.

In the early 1950s, another modification was developed for breaststroke. Breaking the water surface increases drag, reducing speed; swimming underwater increases speed. This led to a controversy at the 1956 Summer Olympics in Melbourne, when six swimmers were disqualified, as they repeatedly swam long distances underwater. However, a Japanese swimmer, Masaru Furukawa, circumvented the rule by not surfacing at all after the start, but swimming as much of the length underwater as possible before breaking the surface.

This speed requires the full extension of the flaps, but this step was not carried out. The nose gear was showing an unsafe indication; should the flaps be extended fully without the nose gear down, a horn would blow, which could not be silenced without retracting the flaps. The captain recycled the gear, but the indicator light still showed an unsafe condition. Meanwhile, the first officer believed that the flaps were fully extended, and started reducing speed to .

Wind from the NNW and a rough sea caused the ship to roll heavily, so that there was difficulty feeding coal to the boilers and two had to be extinguished, reducing speed to by around 22:00. Stoker John Collins reported that in the early morning of the 18th, the crew could hardly stand in the stokehold. By dawn on the 18th, it was possible to increase speed to . At 07:00, the 'Outer Dowsing' lightvessel was seen about away.

Squat effect is approximately proportional to the square of the speed of the ship. Thus, by reducing speed by half, the squat effect is reduced by a factor of four. Squat effect is usually felt more when the depth/draft ratio is less than four or when sailing close to a bank. It can lead to unexpected groundings and handling difficulties. It was a cause of the 7 August 1992 grounding of the Queen Elizabeth 2 (QE2) off Cuttyhunk Island, near Martha's Vineyard.

The many plesiosaur species may have differed considerably in their swimming speeds, reflecting the various body shapes present in the group. While the short-necked "pliosauromorphs" (e.g. Liopleurodon) may have been fast swimmers, the long-necked "plesiosauromorphs" were built more for manoeuvrability than for speed, slowed by a strong skin friction, yet capable of a fast rolling movement. Some long- necked forms, such as the Elasmosauridae, also have relatively short stubby flippers with a low aspect ratio, further reducing speed but improving roll.

An off-duty pilot, Dennis Edward Fitch, joined Haynes and his co-pilot, William Roy Records, and flight engineer Dudley Joseph Dvorak, on the flight- deck. The plane was diverted to Sioux City, for an emergency landing. With his very limited ability to control the plane Haynes had difficulty lining up on a runway, and performing the crucial step of reducing speed and landing nose-up. Consequently the plane came in at almost twice the desired landing speed, with catastrophic damage to the airframe.

The wind was slight. Conditions of visibility were in general poor due to the enemy position close against shorelines of Salvo and Guadalcanal Islands. Radar ranges accurately obtainable only when enemy drew away from close island backgrounds. 3\. Estimated order of events follows as all logs and records went down with the ship. The formations as described steamed on course 150 True between Florida and Savo Islands until approximately 00:20, reducing speed from 23 to 17 knots in search of the reported enemy.

Department for Transport (2009), p.180 "First 20mph zones introduced" and then speed limiters for buses and coaches set at and also for HGVs set at in 1994.Department for Transport (2009), p.181 "Speed limiter settings lowered to 65 mph for new buses and coaches and to 56 mph for HGVs." It was made easier for local authorities to introduce a limit in 1999. In March 2009 the Government consulted on reducing speed limits on rural roads (on which 52% of fatalities had occurred in the previous year) to 50 mph.

Reducing speed to conserve fuel, Auk was taken in tow by Swallow later that day, the former hoisting sail to help in keeping on course. On the morning of the 10th, Auk went alongside Black Hawk in an attempt at underway replenishment, only to have the fuel hose carry away and foul the minesweeper's propeller. Black Hawk then towed Auk throughout the night. In another attempt at refueling between 0925 and 1115 the next morning, Auk took on board 20 tons of oil and reached Grassy Bay, Bermuda, six hours later.

Their debut album Sumerian Cry arrived in 1990 and featured "slightly above average death metal". Their third album Clouds was released in 1993 as the band's first turning-point, "starkly reducing speed and heaviness for melody and atmosphere". The album made an impact on the European metal community for its atmospheric doom metal approach "enhanced with keyboards which are never out of place or over-used". The next album Wildhoney was unveiled in 1994 as an "artistic and commercial breakthrough, fully realizing the sound hinted at on previous releases and eliciting effusive praise in metal circles for its brooding, Gothic atmospherics".

However, when headlights approach a nocturnal animal, it is hard for the creature to see the approaching car (nocturnal animals see better in low than in bright light). Furthermore, the glare of oncoming vehicle headlights can dazzle some species, such as rabbits; they will freeze in the road rather than flee. It may be better to flash the headlights on and off, rather than leaving them on continuously while approaching an animal. The simple tactics of reducing speed and scanning both sides of the road for foraging deer can improve driver safety at night, and drivers may see the retro-reflection of an animal's eyes before seeing the animal itself.

The first group of APDs (APD-1 through APD-36) were converted from one , 17 , and 14 "flush-deck" destroyers built during and after World War I. Some of these had been previously converted to aircraft tenders or other uses. In the conversion, the two forward boilers (out of four) were removed along with their smokestacks (reducing speed to ). Accommodation for 200 troops was installed in the former engine spaces. The original armament of four 4-inch guns, one 3-inch AA gun, and twelve 21-inch torpedo tubes was replaced with three modern 3-inch AA guns, one 40 mm AA gun, and five 20 mm AA guns.

This turnout setting would have caused the absolute signal at the Dalehurst control point to display a stop indication for the freight train. The crew of the freight train would have received a warning of the upcoming stop signal indication when they passed a double-aspect approach signal east of Dalehurst. The signal in question showed an approach indication, yellow over red, meaning that the crew was required to prepare to stop at the next signal while reducing speed to . As the freight train approached this signal, the throttle was in the 8th notch with the train speed at , faster than the speed limit on this stretch of track.

In weapons firing supersonic ammunition, the bullet itself produces a loud and very sharp sound as it leaves the muzzle in excess of the speed of sound and gradually reducing speed as it travels downrange. This is a small sonic boom, and is referred to in the firearm field as "ballistic crack" or "sonic signature". Subsonic ammunition eliminates this sound, but at the cost of lower velocity, resulting in decreased range and much decreased muzzle energy, thus lessening effectiveness on the target; this can be compensated for by increasing bullet weight. For example, if the muzzle velocity is reduced from (common for the .308 Winchester, for example) to a subsonic , the muzzle energy is reduced by a factor of 8.

The booster would be equipped with an RD-191 rocket engine burning kerosene and liquid oxygen to provide approximately 200 tons of thrust. In addition, it would be equipped with a folding wing stored parallel to the fuselage of the vehicle during the booster stage of the flight. After separation from the Angara launcher's second stage at an altitude of about 75 kilometers and a speed of , the Baikal's wing would rotate 90 degrees and the booster glides in upside down position reducing speed. Once the booster reaches subsonic speeds, a U-turn is performed and an air-breathing RD-33 jet engine in its nose section is started to fly back to its launching site and make a powered horizontal landing on a runway.

Under certain conditions, if the PCAM systems determine that the possibility of a frontal crash with a pedestrian or bicyclist is high, it prompts the driver to take evasive action and brake by using an audio and visual alert. If the driver notices the hazard and brakes, the system may use some sort of brake assist to provide additional braking force. If the driver does not brake in a set time and the PCAM determine that the risk of collision with a pedestrian or bicycle is extremely high, the system may automatically apply the brakes, reducing speed to help mitigate the impact or avoid the collision entirely if possible. Usually, this is a setting the driver must make to initiate earlier, but it can be the default.

The primary risk of an electronic train control system is that if the communications link between any of the trains is disrupted then all or part of the system might have to enter a failsafe state until the problem is remedied. Depending on the severity of the communication loss, this state can range from vehicles temporarily reducing speed, coming to a halt or operating in a degraded mode until communications are re-established. If communication outage is permanent some sort of contingency operation must be implemented which may consist of manual operation using absolute block or, in the worst case, the substitution of an alternative form of transportation.ETRMS Level 3 Risks and Benefits to UK Railways, pg 19 Transport Research Laboratory.

However, there was an urgent need to develop an alternate way of drastically reducing speed on landing that would not cause the pilot to lose sight of what was ahead of him. This led to the development of a new air braking system with additional flaps, mounted on the wing, that opened in two directions simultaneously. This wing- mounted design allowed the effective surface area of the flaps to be increased by 100 percent for landing, producing substantially more drag than the conceptual fuselage design and resulting in a sharper reduction in air speed. This meant that the pilot was able to see the landing strip in front of the aircraft as there was no longer the need to tilt the nose upwards at a steep angle at close to stalling speeds.

The TTZ was revised in May 1936 by Admiral Orlov, Commander of the Soviet Navy, reducing speed to , and weakening the secondary and anti-aircraft batteries. A few months later Admiral Orlov further reduced the size of the battleship to 45,000 tons and set the size of the main guns at 406 mm. Shortly afterward, the Soviet Union signed the Anglo-Soviet Quantitative Naval Agreement of 1937 and agreed to follow the terms of the Second London Naval Treaty that limited battleships to a displacement of 35,560 metric tons (35,000 long tons), although they did add a proviso that allowed them to build ships of unlimited size to face the Imperial Japanese Navy if they notified the British. Yet another TTZ was approved by Orlov on 3 August for ships of 41,500 tons with an armament of nine 406-millimeter, twelve , twelve , and forty guns, a maximum armor thickness of and a speed of 30 knots.

The 30 mph (48 km/h) speed limit in built-up areas was introduced in 1934 in response to high casualty levels. The 70 mph (112 km/h) limit on previously unrestricted roads was introduced in 1965 following a number of serious motorway accidents in fog earlier the same year. The Department for Transport believes that effective speed management involves many components but that speed limits play a 'fundamental role' and are 'a key source of information to road users' particularly as an indicator of the nature and risks posed by that road to both themselves and other motorised and non-motorised road users. The Parliamentary Select Committee for Transport Safety published a report entitled 'The Ending the Scandal of Complacency' in 2007 which highlighted how casualty levels rise with increasing speed and recommended reducing speed limits on streets with high pedestrian populations and on dangerous rural roads. The report highlights that when two cars crash head-on at 60 mph a driver has a 90% chance of dying which falls to 65% at 50 mph.

These three new prestressed concrete girder bridges replaced arch bridges built in 1857. The longest set of points in the world was installed in Bitterfeld station in January 1998. This 169.2 metre-long construction is passable at 220 km/h (in normal operations at up to 200 km/h) on the diverging track. Switch 03 at the northern end of Bitterfeld station thus allows trains from Leipzig to Berlin to pass through on the line from Halle without reducing speed. The point blades are each 59 metres long and weigh 120 tons, including their support mechanism. In preparation for the installation of the European Train Control System (ETCS), a 15 km test section between Bitterfeld and Gräfenhainichen was put into full operation in 2001. To adapt the control system of the Deutsche Bahn to the newly agreed European Standard, ETCS Level 2 was installed on part of this line for the first time in Germany. Around 1,200 balises were installed. On 26 May 2006, a pair of Intercity (IC) services (2418/2419) were equipped with ETCS for speeds of up to 200 km/h.
