A government, business or institution's inability to function at a normal level due either to complex or conflicting procedures within the administrative framework or to impending change in the business.

Investopedia Says:
In business as in traffic, little to nothing gets done when gridlock happens. This can be highly problematic and costly for a company or industry. For example, gridlock can occur if there is infighting within a company, with two groups competing to gain control of the company. This infighting can effectively create a situation in which business transactions cannot be completed until the problem is solved.

Word Origin: gridlock

Origin: 1980

Thanks to traffic engineers, we are no longer stuck for a word about getting stuck. It's gridlock, where the flow of traffic through the grid of intersecting streets is locked into immobility. In a city, this happens when cars cannot clear an intersection after the lights have changed. On highways, too many cars trying to enter an already full road may have the same effect. The New York Times Magazine introduced the word to nonspecialists in 1980: "'gridlock' is to highway engineers what 'meltdown' is to nuclear engineers--a panic inside a nightmare inside a worst case. Instead of going with the traffic flow, everything stops and every frenzied driver leans on his horn."

It was too good a word to leave to the engineers. By the early 1980s, any kind of complete stoppage or jam could be called gridlock, and the resulting terms ranged from telephone gridlock (1984), used when overcrowded telephone lines give everyone a busy signal, and corporate gridlock (1985), when a corporation is stuck in its traditional ways, to vocal gridlock (1983), the condition of being too frightened to speak, rare in our talkative world. Politicians have made the most of gridlock, including legislative gridlock (1982), when a divided legislature is unable to act, and government gridlock (1995), when the president and Congress shut down the federal government because they are at odds.



Wikipedia: Gridlock

Gridlock on a network of one-way streets. The red cars are those causing the gridlock by stopping in the middle of the intersection.

Gridlock is a term describing an inability to move on a transport network. The term originates from a situation possible in a grid network where intersections are blocked, preventing vehicles from either moving forwards through the intersection or backing up to an upstream intersection.

The term gridlock is also widely used to describe high traffic congestion with minimal flow (a "traffic jam"), whether or not a blocked grid system is involved. By extension, the term has been applied to situations in other fields where flow is stalled by excess demand, or in which competing interests prevent progress.

Cause

The traditional form of gridlock is caused by traffic heading in one direction blocking cross traffic at an intersection. In many jurisdictions, drivers are prohibited from entering an intersection at a green light if there is no room for them to clear the intersection. If drivers follow this rule of the road, gridlock will be prevented and traffic will only be slow in the direction that is actually congested. One method of reducing gridlock is to aggressively enforce penalties for vehicles that block intersections.[1]

Another type of gridlock can occur during traffic surges between highway on-ramps and off-ramps located within a quarter mile of each other. Traffic exiting the highway may back up and block the entering vehicles.

Gridlock is sometimes cited as an example of the prisoner's dilemma (from game theory).[2] Mutual cooperation among drivers would give the maximum benefit (prevention of gridlock), but this may not happen because of the desire to maximize one's own benefit (shortest travel time) given the uncertainty about the other drivers' commitment to cooperation.

Enforcement

New York City

Vehicles and pedestrians "blocking the box" in New York City

In New York City, drivers who "block the box" are subject to a moving violation that comes with a US$90.00 penalty. Mayor Michael Bloomberg, noting that the ten minute ticketing process actually contributes to overall traffic congestion, has recently asked the New York State Legislature to remove “blocking the box” from the moving violation category. This reclassification would give more traffic agents authority to write tickets and change the current ticketing procedure, which requires that the issuing officer physically stop the violating car in traffic.[3]

Virginia Beach, Virginia

In Virginia Beach, Virginia, roads around the oceanfront feature signs at every intersection stating "Don't Block the Box", and threatening a $200 fine. It is also illegal to cruise along Atlantic Avenue in the city, due to the heavy pedestrian and vehicular traffic in the area during the summer months.

Effects

The obvious impacts are driver frustration and trip delay. Another impact in cities is exacerbated by the presence of urban street canyons, which effectively trap air pollution and increase air pollution exposures of motorists as well as the general urban population. Noise pollution can be aggravated by excessive starting and stopping noise of gridlocked facilities.[4]

Etymology

The first appearances of the word gridlock in newspapers occurred during the 1980 New York City transit strike. The word is attributed to Sam Schwartz, who was the chief traffic engineer for the city's Department of Transportation at the time of the strike.[5] Schwartz said the word gridlock was used internally in his department during the 1970s, perhaps as early as 1971.[6]
