The name is sometimes a misnomer, as the peak period often lasts more than one hour and the "rush" refers to the volume of traffic, not the speed of its flow. Rush hour may be 5–9 AM (5:00–9:00) and 4–8 PM (sometimes from 4-9 PM) (16:00–20:00 (sometimes from 16:00-21:00)). In many cities over 1 million inhabitants, it sometimes even takes place at noon from 11 AM - 1 PM (11:00-13:00). Peak traffic periods may vary from country to country, city to city, from region to region, and seasonally.
Efforts to minimise traffic congestion during peak hour vary on a state by state and city by city basis.

Traffic congestion is managed through the Traffic Management Centre via a network of Closed Circuit TV's, with operators able to change the timing of traffic signals to reduce wait times
For trains in the Netherlands there is an off-peak discount available, giving a 40% discount. Its validity starts at 9am (until 4am the next morning) on weekdays, and all day at weekends and in July and August. In the case of a group of up to four people, all get the discount even if only one has a pass.
Rail passes not requiring an additional ticket come in two versions: for a fixed route, and for the whole network. Both are mainly used by commuters. No off-peak discount version of these passes is offered since there is insufficient demand; commuters usually cannot avoid the rush hour.
This table shows the license plates with numbers ending with its corresponding days:
Exempted from the program are motorcycles, school buses, shuttle buses, ambulances, fire engines, police cars, military vehicles, those carrying a person needing immediate medical attention, and vehicles with diplomatic license plates.
On the other hand, in other places, there are certain policies the municipal or city government are proposing or has implemented for the whole municipality or city.
In Singapore, there is a free travel scheme before 7:45 am and 50 cent discount between 7:45 am and 8 am, which applies only if you exit and not enter at the 18 CBD stations. This is an attempt to encourage commuters' travel on the MRT outside the crowded weekday morning peak. Electronic Road Pricing is intended to discourage driving between 7:30 am and 8 pm. In addition, employees were given travel incentives through Travel Smart programme. Peak hours are defined as follows: 7:30–9:30 am and 5–8 pm, with different times for terminal stations.
There is also an afternoon rush hour. For example, in the New York City area, the afternoon rush hour can begin as early as 2:30-3pm and last until 7-7:30pm. Some people who live in Connecticut but work in New York often do not arrive home until 7 pm or later. On the other hand, in a smaller city like Cleveland, the afternoon rush hour takes place in a more literal sense such that heavy traffic congestion typically only occurs between 5 and 6 pm. Usually the RTA in Cleveland has an afternoon rush hour schedule like the morning.
Another usage of "third rush hour" can be to describe congestion later at night (generally between 10–11 pm and 2–3 am the next morning, particularly on Thursdays, Fridays, and Saturdays) of people returning home from nights spent out at restaurants, bars, nightclubs, casinos, concerts, amusement parks, movie theaters, and sporting events. At other times (such as evenings and weekends), additional periods of congestion can be the result of various special events, such as sports competitions, festivals, or religious services. Out-of-the-ordinary congestion can be the result of an accident, construction, long holiday weekends, or inclement weather.
