Summary
Bus rapid transit (BRT) significantly boosts transit ridership. Comparing BRT routes to conventional bus service in King County showed a 35% increase, confirming BRT
Area of Science:
- Transportation science
- Urban planning
- Public transit analysis
Background:
- Bus rapid transit (BRT) implementation often correlates with increased ridership.
- Previous studies faced challenges isolating BRT's impact from general transit trends.
Purpose of the Study:
- To determine the causal effect of Bus rapid transit (BRT) on transit ridership.
- To quantify the independent impact of BRT by comparing it to control routes.
Main Methods:
- Compared ridership data from 2010, 2013, and 2014 in King County, Washington.
- Analyzed routes with new BRT implementation against routes with conventional service and existing BRT.
Main Results:
- Routes with new BRT saw a 35% ridership increase from 2010-2013 versus conventional routes.
- Routes with new BRT experienced a 29% increase from 2013-2014 compared to established BRT routes.
Conclusions:
- BRT implementation shows a strong causal relationship with increased transit ridership.
- This study provides a more accurate estimate of BRT's independent effect on passenger numbers.

Calculating subtransient fault currents for three-phase faults in an N-bus power system involves using the positive-sequence network. When a three-phase short circuit occurs at a specific bus, the analysis uses the superposition method to evaluate two separate circuits.
In the first circuit, all machine voltage sources are short-circuited, leaving only the prefault voltage source at the fault location. The positive-sequence bus impedance matrix can be determined by solving the nodal equations,...

01:52Regression Toward the Mean
7.2K
Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when...

Persuasion is the process of changing our attitude toward something based on some kind of communication. Much of the persuasion we experience comes from outside forces. How do people convince others to change their attitudes, beliefs, and behaviors? What communications do you receive that attempt to persuade you to change your attitudes, beliefs, and behaviors?

Social traps are negative situations where people get caught in a direction or relationship that later proves to be unpleasant, with no easy way to back out of or avoid. The concept was orignally introduced by John Platt who applied psychology to Garrett Hardin's "Tragedy of the Commons", where in New England herd owners could let their cattle graze in the common ground. This situation seems like a good idea, but an individual could have an advantage. If they owned...

Cognitive processes affect social behavior by guiding how individuals perceive, interpret, and respond to social stimuli. These mental processes enable individuals to assess others' behaviors, attribute causes to their actions, and form expectations based on past experiences.Causes of Behavior and Social JudgmentsIndividuals determine the causes of others' behaviors by distinguishing between personal traits and external circumstances. For example, if a friend frequently arrives late, an...

The discussion of bullying highlights the problem of witnesses not intervening to help a victim. This is a common occurrence, as the following well-publicized event demonstrates. In 1964, in Queens, New York, a 19-year-old woman named Kitty Genovese was attacked by a person with a knife near the back entrance to her apartment building and again in the hallway inside her apartment building. When the attack occurred, she screamed for help numerous times and eventually died from her stab wounds.
