Carpooling Essay

The money you’ll save from reduced fuel usage is one of the best reasons to carpool. Depending on the size of your carpool and distance of your commute, you could save hundreds or thousands of dollars every year. But carpooling doesn’t just benefit your wallet; it can positively affect the environment and the traffic in your area, and it can add usable time to your day. Here are five ways carpooling does more than just save gas.

  1. Reduce your carbon footprint – According to rideshare.com, every car annually emits its own weight in carbon dioxide into the atmosphere. Carpooling reduces that amount significantly. If you carpool to and from work, you could probably cut your transportation emissions number in half, or even better.
  2. Use of carpool lanes – Many major metropolitan areas have specially designated carpool lanes that are reserved for vehicles with two or more passengers. These lanes are typically less congested than typical freeway lanes, which means your commute time could be reduced considerably if you travel with coworkers.
  3. Usable commute time – If you drive to work alone every day, the time spent behind the wheel is essentially wasted. Driving demands our complete attention, which means it’s difficult to be productive with your time on the road. Riding in a carpool allows you to check and answer email, read the news, check bank balances, or even close your eyes for a few minutes before starting your day.
  4. Save money – In addition to the money you’ll save by using less gas, some cities have initiated programs that reward carpoolers with cash. The Clean Air Campaign, located in Georgia, motivates carpooling with money and prizes.
  5. Reduce traffic congestion – The benefits of carpooling on a large scale are huge. Every carpooling participant takes another car off the road, which means less congested roads and highways. As more people take part in carpooling programs or organize carpools within their workplaces, overall traffic congestion will decrease, which reduces fuel consumption, commute time, and the cost of road repairs.

Carpooling is beneficial on an individual level and for your community as a whole. It can reduce air pollution while saving you money in the process. If you’re considering carpooling as a way to save money on vehicle expenses, consider other strategies such as comparing auto insurance quotes or auto loan refinance rates, as well. It’s a good idea to revisit these monthly bills occasionally to ensure that you’re not overpaying, especially since auto loan rates can fluctuate throughout the year.

Carpooling (also car-sharing, ride-sharing and lift-sharing) is the sharing of car journeys so that more than one person travels in a car, and prevents the need for others to have to drive to a location themselves.

By having more people using one vehicle, carpooling reduces each person's travel costs such as: fuel costs, tolls, and the stress of driving. Carpooling is also a more environmentally friendly and sustainable way to travel as sharing journeys reduces air pollution, carbon emissions, traffic congestion on the roads, and the need for parking spaces. Authorities often encourage carpooling, especially during periods of high pollution or high fuel prices. Car sharing is a good way to use up the full seating capacity of a car, which would otherwise remain unused if it were just the driver using the car

In 2009, carpooling represented 43.5% of all trips in the United States[1] and 10% of commute trips.[2] The majority of carpool commutes (over 60%) are "fam-pools" with family members.[3]

Carpool commuting is more popular for people who work in places with more jobs nearby, and who live in places with higher residential densities.[4] Carpooling is significantly correlated with transport operating costs, including fuel prices and commute length, and with measures of social capital, such as time spent with others, time spent eating and drinking, and being unmarried. However, carpooling is significantly less likely among people who spend more time at work, elderly people, and homeowners.[3]


Drivers and passengers offer and search for journeys through one of the several mediums available. After finding a match they contact each other to arrange any details for the journey(s). Costs, meeting points and other details like space for luggage are agreed on. They then meet and carry out their shared car journey(s) as planned.

Carpooling is commonly implemented for commuting but is increasingly popular for longer one-off journeys, with the formality and regularity of arrangements varying between schemes and journeys.

Carpooling is not always arranged for the whole length of a journey. Especially on long journeys, it is common for passengers to only join for parts of the journey, and give a contribution based on the distance that they travel. This gives carpooling extra flexibility, and enables more people to share journeys and save money.

Some carpooling is now organized in online marketplaces or ridematching websites that allow drivers and passengers to find a travel match and/or make a secured transaction to share the planned travel cost. Like other online marketplaces, they use community-based trust mechanisms, such as user-ratings, to create an optimal experience for users.

Arrangements for carpooling can be made through many different mediums including public websites, social media, acting as marketplaces, employer websites, smartphone applications, carpooling agencies and pick-up points.


Many companies and local authorities have introduced programs to promote carpooling.

In an effort to reduce traffic and encourage carpooling, some governments have introduced high-occupancy vehicle (HOV) lanes in which only vehicles with two or more passengers are allowed to drive. HOV lanes can create strong practical incentives for carpooling by reducing travel time and expense.[5] In some countries it is common to find parking spaces reserved for carpoolers.

In 2011, an organization called Greenxc[6] created a campaign to encourage others to use this form of transportation in order to reduce their own carbon footprint.

Carpooling, or car sharing as it is called in British English, is promoted by a national UK charity, Carplus, whose mission is to promote responsible car use in order to alleviate financial, environmental and social costs of motoring today, and encourage new approaches to car dependency in the UK. Carplus is supported by Transport for London, the British government initiative to reduce congestion and parking pressure and contribute to relieving the burden on the environment and to the reduction of traffic related air-pollution, in London.[7]

However, not all countries are helping carpooling to spread: in Hungary it is a tax crime to carry someone in a car for a cost share (or any payment) unless the driver has a taxi license and there is an invoice issued and taxes are paid. Several people were fined by undercover tax officers during a 2011 crackdown, posing as passengers looking for a ride on carpooling websites. On 19 March 2012 Endre Spaller, a member of the Hungarian Parliament interpellated Secretary of the State X about this practice who replied that carpooling should be endorsed instead of punished, however care must be taken for some people trying to turn it into a way to gain untaxed profit.[8]

Cost sharing[edit]

Carpooling usually means to divide the travel expenses in equal parts between all the occupants of the vehicle (driver or passenger). The driver doesn’t try to earn money, but to share with several people the cost of a trip he would do anyway. The expenses to be divided basically include the fuel and possible tolls. But if we include in the calculation the depreciation of the vehicle purchase and maintenance, insurance and taxes paid by the driver, we get a cost around $1/mile. There are platforms that facilitate carpooling by connecting people seeking respectively passengers and drivers. Usually there is a fare set up by the car driver and accepted by passengers, because they get an agreement before trip start.

The second generation of these platforms is designed to manage urban trips in real time, using the travellers’ smartphones. They make possible to occupy the vehicle’s empty seats on the fly, collecting and delivering passengers along its entire route (and not only at common points of origin and destination). This system automatically performs an equitable sharing of travel costs, allowing each passenger to reimburse the driver a fair share according to the benefit actually gained by the vehicle usage, proportional to the distance traveled by the passenger and the number of people that shared the car.


Carpooling first became prominent in the United States as a rationing tactic during World War II. It returned in the mid-1970s due to the 1973 oil crisis and the 1979 energy crisis. At that time the first employee vanpools were organized at Chrysler and 3M.[9]

Carpooling declined precipitously between the 1970s and the 2000s, peaking in the US in 1970 with a commute mode share of 20.4%. By 2011 it was down to 9.7%.[10] In large part this has been attributed to the dramatic fall in gas prices (45%) during the 1980s.[11] The character of carpool travel has been shifting from the "Dagwood Bumstead" variety, in which each rider is picked up in sequence, to a "park and ride" variety, where all the travelers meet at a common location.[3]

Recently, however, the Internet has facilitated growth for carpooling and the commute share mode has grown to 10.7% in 2005.[10] The popularity of the Internet and mobile phones has greatly helped carpooling to expand, enabling people to offer and find rides thanks to easy-to-use and reliable online transport marketplaces. These websites are commonly used for one-off long-distance journeys with high fuel costs.

In Europe, long-distance car-pooling has become increasingly popular over the past years, thanks to Germany's Mitfahrgelegenheit (carpooling.com), and France's BlaBlaCar.[12] According to their respective websites, in early 2015 these online platforms counted more than 6 million[13] and 10 million[14] users respectively, across Europe and beyond.

Other forms[edit]

Carpooling exists in other forms:

  • Slugging is a form of ad hoc, informal carpooling between strangers. No money changes hands, but a mutual benefit still exists between the driver and passenger(s) making the practice worthwhile.
  • Flexible carpooling expands the idea of ad hoc carpooling by designating formal locations for travelers to join carpools.
  • Real-time ridesharing allows people to arrange ad hoc rides on very short notice, through the use of smartphone applications or the internet. Passengers are simply picked up at their current location.
  • Odd-Even formula, a kind of car pool concept was adopted by state government in Delhi, India.
  • Multi-hop ride sharing denotes the re-combination of existing rides (e.g., A to X, X to B) to travel from A to B via X.[15]
  • Long distance ridesharing, in contrast to short-distance or local ridesharing.


  • Flexibility - Carpooling can struggle to be flexible enough to accommodate en route stops or changes to working times/patterns. One survey identified this as the most common reason for not carpooling.[5] To counter this some schemes offer 'sweeper services' with later running options, or a 'guaranteed ride home' arrangement with a local taxi company.
  • Reliability - If a carpooling network lacks a "critical mass" of participants, it may be difficult to find a match for certain trips. The parties may not necessarily follow through on the agreed-upon ride. Several internet carpooling marketplaces are addressing this concern by implementing online paid passenger reservation, billed even if passengers do not turn up.
  • Riding with strangers - Concerns over security have been an obstacle to sharing a vehicle with strangers, though in reality the risk of crime is small.[16] One remedy used by internet carpooling schemes is reputation systems that flag problematic users and allow responsible users to build up trust capital, such systems greatly increase the value of the website for the user community.
  • Overall efficacy - Though carpooling is officially sanctioned by most governments, including construction of lanes specifically allocated for car-pooling, some doubts remain as to the overall efficacy of carpool lanes. As an example, many car-pool lanes, or lanes restricted to car-pools during peak traffic hours, are seldom occupied by car-pools in the traditional sense[citation needed]. Instead, these lanes are often empty, leading to an overall net increase in fuel consumption as freeway capacity is intentionally contracted, forcing the solo-occupied cars to travel slower, leading to reduced fuel efficiency. Further, many of the vehicles are occupied by passengers that would nevertheless consist of multiple passengers, for example a parent with multiple children being escorted to school.
  • In 2012, the Queensland government announce it would end car pool lanes (known as Transit Lanes) claiming they were creating congestion and delays. The move was supported by the RACQ motoring group.[17]

In popular culture[edit]

Cabbing All the Way is a book written by author Jatin Kuberkar that narrates a success story of a car pool with twelve people on board. Based in the city of Hyderabad, India, the book is a real life narration and highlights the potential benefits of having a car pool.[18]
