Samuel I. Schwartz, also known as Gridlock Sam, is an American transportation engineer, formerly the New York City Traffic Commissioner, notable for popularizing the phrase "gridlock". [1]
Schwartz was educated at Brooklyn College (BS Physics) and the University of Pennsylvania (MSCE), and first worked as a New York City cabbie before being hired by the City of New York in 1971. [2] He served as NYC Traffic Commissioner from 1982 to 1986, and when the traffic department became subsumed by the Department of Transportation he held the second-in-command post of First Deputy Commissioner and Chief Engineer from 1986-1990. While employed with the city, he attempted to introduce bicycle lanes and public plazas. They were vetoed at the last minute by then-mayor John Lindsay. [2] He earned the nickname Gridlock Sam during the 1980 transit strike when he developed a series of transportation contingency plans, called the Grid-Lock Prevention Program. [2]
It was under Schwartz's watch that the city almost became the first city to implement congestion pricing. The city's bridges had not been tolled since 1911 and beginning in 1973 he worked with Mayor Lindsay to reintroduce them. Even with a change in leadership (Mayor Lindsay was replaced by Abe Beame in 1974) it looked like the tolls would be reinstated. However, an act of Congress nixed the proposal in 1977.

After he left city government around 1996, he started his own firm. [2] He writes columns for New York City's Daily News , lower Manhattan’s Downtown Express, The Queens Chronicle and in the Yiddish News Report as Gridlock Shmuel. He also tweets, and blogs for the Public Broadcasting Service and Engineering News-Record .[ citation needed ]
Transport economics is a branch of economics founded in 1959 by American economist John R. Meyer that deals with the allocation of resources within the transport sector. It has strong links to civil engineering. Transport economics differs from some other branches of economics in that the assumption of a spaceless, instantaneous economy does not hold. People and goods flow over networks at certain speeds. Demands peak. Advance ticket purchase is often induced by lower fares. The networks themselves may or may not be competitive. A single trip may require the bundling of services provided by several firms, agencies and modes.
A high-occupancy vehicle lane is a restricted traffic lane reserved for the exclusive use of vehicles with a driver and at least one passenger, including carpools, vanpools, and transit buses. These restrictions may be only imposed during peak travel times or may apply at all times. There are different types of lanes: temporary or permanent lanes with concrete barriers, two-directional or reversible lanes, and exclusive, concurrent, or contraflow lanes working in peak periods.
A toll road, also known as a turnpike or tollway or toll gate, is a public or private road for which a fee is assessed for passage. It is a form of road pricing typically implemented to help recoup the costs of road construction and maintenance.
The San Francisco–Oakland Bay Bridge, known locally as the Bay Bridge, is a complex of bridges spanning San Francisco Bay in California. As part of Interstate 80 and the direct road between San Francisco and Oakland, it carries about 260,000 vehicles a day on its two decks. It includes one of the longest bridge spans in the United States.
Road pricing are direct charges levied for the use of roads, including road tolls, distance or time-based fees, congestion charges and charges designed to discourage the use of certain classes of vehicle, fuel sources or more polluting vehicles. These charges may be used primarily for revenue generation, usually for road infrastructure financing, or as a transportation demand management tool to reduce peak hour travel and the associated traffic congestion or other social and environmental negative externalities associated with road travel such as air pollution, greenhouse gas emissions, visual intrusion, noise pollution and road traffic collisions.
Congestion pricing or congestion charges is a system of surcharging users of public goods that are subject to congestion through excess demand, such as through higher peak charges for use of bus services, electricity, metros, railways, telephones, and road pricing to reduce traffic congestion; airlines and shipping companies may be charged higher fees for slots at airports and through canals at busy times. Advocates claim this pricing strategy regulates demand, making it possible to manage congestion without increasing supply.
Traffic congestion is a condition in transport that is characterized by slower speeds, longer trip times, and increased vehicular queueing. Traffic congestion on urban road networks has increased substantially since the 1950s. When traffic demand is great enough that the interaction between vehicles slows the traffic stream, this results in congestion. While congestion is a possibility for any mode of transportation, this article will focus on automobile congestion on public roads.
Gridlock is a form of traffic congestion where "continuous queues of vehicles block an entire network of intersecting streets, bringing traffic in all directions to a complete standstill". The term originates from a situation possible in a grid plan where intersections are blocked, preventing vehicles from either moving forwards through the intersection or backing up to an upstream intersection.
Electronic toll collection (ETC) is a wireless system to automatically collect the usage fee or toll charged to vehicles using toll roads, HOV lanes, toll bridges, and toll tunnels. It is a faster alternative which is replacing toll booths, where vehicles must stop and the driver manually pays the toll with cash or a card. In most systems, vehicles using the system are equipped with an automated radio transponder device. When the vehicle passes a roadside toll reader device, a radio signal from the reader triggers the transponder, which transmits back an identifying number which registers the vehicle's use of the road, and an electronic payment system charges the user the toll.
In economics, induced demand – related to latent demand and generated demand – is the phenomenon whereby an increase in supply results in a decline in price and an increase in consumption. In other words, as a good or service becomes more readily available and mass produced, its price goes down and consumers are more likely to buy it, meaning that the quantity demanded subsequently increases. This is consistent with the economic model of supply and demand.
Interstate 405 is a major north–south auxiliary Interstate Highway in Southern California. The entire route is known as the northern segment of the San Diego Freeway. I-405 is a bypass auxiliary route of I-5, running along the southern and western parts of the Greater Los Angeles urban area from Irvine in the south to Sylmar in the north.
Anthony Downs was an American economist specializing in public policy and public administration. His research focuses included political choice theory, rent control, affordable housing, and transportation economics. He wrote a number of books including, An Economic Theory of Democracy (1957) and Inside Bureaucracy (1967), which have been major influences on the public choice school of political economy. In Downs's Law of Peak-Hour Traffic Congestion (1962), he predicted that expanding expressways could not reduce traffic congestion, since demand would increase as well, and that reducing speeds increases capacity.
The Virginia Department of Transportation (VDOT) is the agency of the state government responsible for transportation in the state of Virginia in the United States. VDOT is headquartered at the Virginia Department of Highways Building in downtown Richmond. VDOT is responsible for building, maintaining, and operating the roads, bridges, and tunnels in the commonwealth. It is overseen by the Commonwealth Transportation Board, which has the power to fund airports, seaports, rail, and public transportation.
The Edinburgh congestion charge was a proposed scheme of congestion pricing for Scotland's capital city. It planned to reduce congestion by introducing a daily charge to enter a cordon within the inner city, with the money raised directed to fund improvements in public transport. The scheme was the subject of intense public and political debate and ultimately rejected. A referendum was held and nearly three-quarters of respondents rejected the proposals.
Open road tolling (ORT), also called all-electronic tolling, cashless tolling, or free-flow tolling, is the collection of tolls on toll roads without the use of toll booths. An electronic toll collection system is usually used instead. The major advantage to ORT is that users are able to drive through the toll plaza at highway speeds without having to slow down to pay the toll. In some installations, ORT may also reduce congestion at the plazas by allowing more vehicles per hour/per lane.
Diana Reyna is an American politician who was the deputy borough president for Brooklyn and a member of the New York City Council from the 34th District, which includes Williamsburg and Bushwick as well as Ridgewood in Queens. Reyna ran for lieutenant governor of New York in the 2022 election as U.S. Representative Thomas Suozzi's running mate.
In New York City, a planned congestion pricing scheme will charge vehicles traveling into or within the central business district of Manhattan. First proposed in 2007, this disincentivizing fee to cut down on traffic congestion and pollution was approved and included in the 2019 New York state government budget by the New York State Legislature. As of February 2023, congestion pricing is scheduled to be implemented in the second quarter of 2024. When the congestion charge goes into effect, tolls will be collected electronically and will vary depending on the time of day, type of vehicle, and whether a vehicle has an E-ZPass toll transponder.
There are approximately 25 current toll roads in the state of Texas. Toll roads are more common in Texas than in many other U.S. states, since the relatively low revenues from the state's gasoline tax limits highway planners' means to fund the construction and operation of highways.
San Francisco congestion pricing is a proposed traffic congestion user fee for vehicles traveling into the most congested areas of the city of San Francisco at certain periods of peak demand. The charge would be combined with other traffic reduction projects. The proposed congestion pricing charge is part of a mobility and pricing study being carried out by the San Francisco County Transportation Authority (SFCTA) to reduce congestion at and near central locations and to reduce its associated environmental impacts, including cutting greenhouse gas emissions. The funds raised through the charge will be used for public transit improvement projects, and for pedestrian and bike infrastructure and enhancements.
Electronic road pricing is an electronic toll collection scheme first proposed in Hong Kong as early as in the 1980s to manage traffic by congestion pricing.
