Wet, snowy, or icy roadway surface conditions will also lead to the same effect even after precipitation has ended.

Due to reduced visibility, drivers will usually lower their speeds and increase their headways when precipitation, bright sunlight on the horizon, fog, or smoke are present.

Weather – Environmental conditions can lead to changes in driver behavior that affect traffic flow.

Delays caused by work zones have been cited by travelers as one of the most frustrating conditions they encounter on trips. These changes may include a reduction in the number or width of travel lanes, lane 'shifts,' lane diversions, reduction, or elimination of shoulders, and even temporary roadway closures.

Work Zones – Are construction activities on the roadway that result in physical changes to the highway environment.

Even incidents off of the roadway (a fire in a building next to a highway) can be considered traffic incidents if they affect travel in the travel lanes. In addition to blocking travel lanes physically, events that occur on the shoulder or roadside can also influence traffic flow by distracting drivers, leading to changes in driver behavior and ultimately degrading the quality of traffic flow. Events such as vehicular crashes, breakdowns, and debris in travel lanes are the most common form of incidents.

Traffic Incidents – Are events that disrupt the normal flow of traffic, usually by physical impedance in the travel lanes.

5 These 'seven sources' can be grouped into three broad categories, as shown below: Category 1 - Traffic-Influencing Events Previous work has shown that congestion is the result of seven root causes, often interacting with one another. 2.2ĜAUSES OF CONGESTION AND UNRELIABLE TRAVEL 2.2.1 Background: The Seven Sources of Congestion The rest of this chapter is devoted to describing congestion and how we measure it, as well as its causes and consequences. Congestion often means stopped or stop-and-go traffic. In the transportation realm, congestion usually relates to an excess of vehicles on a portion of roadway at a particular time resulting in speeds that are slower-sometimes much slower-than normal or 'free flow' speeds. The definitions of the term congestion mention such words as 'clog,' 'impede,' and 'excessive fullness.' For anyone who has ever sat in congested traffic, those words should sound familiar. Trends and Advanced Strategies for Congestion MitigationĢ.0 The Nature of Traffic Congestion and Reliability: Causes, How They Are Measured, and Why They Matter 2.1 WHAT IS CONGESTION?Ĭongestion is relatively easy to recognize-roads filled with cars, trucks, and buses, sidewalks filled with pedestrians.

If people do go outside, they should wear high-quality masks - such as a N95 or KN95.Final report Traffic Congestion and Reliability: Be aware of your local air quality and wear masks that can filter out tiny particles, they added.

People should stay indoors, limiting exposure to the smoke as much as possible, including during exercise, experts said.

1 worldwide among cities with the worst air quality and was in Code Purple, signifying very unhealthy levels for the general population. As of the evening, New York ranked No.More than 160 of the fires burning now in Canada are in the province of Quebec, with dozens also reported in Alberta and British Columbia. Canada is on track to experience its worst wildfire season ever, with officials reporting roughly 240 “out of control” active fires.Hints of smoke were even flirting with the Georgia-Florida border. Hazardous particles degraded air people were breathing as far south as South Carolina, and Eastern Pennsylvania recorded some of the worst air quality in the country.
