Why are passengers travelling in a double decker bus allowed to stand in a lower deck, but not in the upper deck? (2023)

FAQs

Why are the passengers Travelling in a double-decker bus allowed to stand on the lower back but not on the upper deck? ›

The passengers travelling in a double-decker bus are allowed to stand on a lower deck, but not on the upper deck, because of the centre of gravity of the bus shift to some more height. it reduces the stability. It makes the passengers difficult to stand and makes them fall.

When the passengers stand, the center of gravity rises. If it rises much it becomes unstable and may topple down.

Double deck buses, normally about 9 and 12 meters in length, but up to 15 meters in some countries and seating between 60 and 120 passengers, are operated on urban services in many countries. Double-deck buses have a number of advantages.

Double-decker buses have heavy weight attached to their undersides to lower the centre of . If an object is tilted it will topple over if a vertical line from its centre of gravity falls outside its base.

This is because double-decker buses are riskier compared to smaller single deck buses. And with the height of the double-decker bus as high as 4.30 meters, engineering is part of the risk factor that leads to road accidents.

This is due to inertia of rest of upper part of the passengers body when the bus or train suddenly starts moving, the lower part of the passenger's body starts moving along with the bus or train while upper part of the body has a tendency to remain in the state of rest due to inertia of rest and hence falls backward.

This is because of inertia of motion. The part of our body, which is in contact with the bus, changes the direction of motion. However, the rest of the body tries to move in the same direction as before because of inertia of motion.

Inertia in a moving bus when the brake is applied

As the driver applies brakes, the bus comes to rest. But, the passenger tries to maintain the inertia of motion. As a result, a forward force is exerted on him.

This is due to inertia. When the speeding bus stops suddenly, lower part of the body comes to rest while the upper part of the body tends to maintain uniform motion. Hence, the passenger's are thrown forward.

Tipping over accidents.

Because double-decker buses are tall, box-shaped and have a high center of gravity, when they are involved in certain types of accidents they are more likely to tip over than other types of buses.

Why doesn t the us have double-decker buses? ›

There are two main reasons double decker transit buses are almost non-existent here in the US: one, low overpasses are very common here, and two, until recently there were no double decker transit buses even available here in the US.

Maximum loading. A maximum of 30 passengers can ride on a double decker bus and the maximum capacity for a single decker is 11 or 14 depending on its size. In addition, standing is not allowed on buses. All maximum loads are clearly marked on buses.

A double decker bus is stable as it has a: low centre of gravity because of its low, heavy engine and heavy bottom deck; wide wheel base.

A school bus crossing arm is a safety device intended to protect children from being struck while crossing in front of a school bus.

The slanted bus stop design has been implemented in large cities like New York, Paris and London in an attempt to prevent the homeless from sleeping in highly populated public spaces. Other architectural measures including armrests, foldable seats, and even spikes have also been used as a means to deter the homeless.

Sit towards the middle of the bus

To find the safest seat on a bus, head for the middle. Choose a row as centrally located as possible and sit on the aisle, choosing the side of the bus farthest from opposing traffic.

Stay away from the back of the bus on the bottom deck and from anyone with a takeaway. Priority seats on the bottom deck are best. Second best is the top deck, three rows from the front, on the aisle seat.

The law of action-reaction (Newton's third law) explains the nature of the forces between the two interacting objects.

The person is in a state of motion, but when they jump out and land on the ground, the lower half of their body comes to an abrupt stop. Due to the inertia of motion, the upper half of their body resists this sudden change in state and continues to move in the direction of the bus, causing the person to roll forward.

Why a passenger standing on the floor of a bus jerks backwards when the lorry starts moving forward? ›

When a bus starts suddenly,its passengers tend to fall backwards because due to their inertia, the passengers tend to remain in a state of rest even when the bus starts moving.

Due to inertia of rest, there is a risk of falling backward or frontward for the passengers while the bus is turning. Because due to inertia of rest passenger's body will tend to remain in the state of the rest and that's why they hold on to prevent themselves from swaying in a turning bus.

When the bus suddenly takes a sharp turn, the lower portion of passengers which is contact with the bus tends to move in that direction but the upper portion of the passengers throw an outside. This happens due to the INERTIA OF DIRECTION.

Passengers are thrown outwards because of inertia of direction.

When the bus accelerates from rest: When a bus abruptly starts moving, the passengers tend to slide backward due to inertia, as the passenger's inertia tends to oppose the bus's forward motion. Hence, the passenger tends to fall back when the bus accelerates forward.

The passengers sitting in the moving bus are pushed in the forward direction when the bus stops suddenly due to inertia because the passengers' upper body continues to be in a state of motion, while the lower part of the body that is in contact with the seat remains at rest.

A person standing in a bus falls backwards when bus suddenly starts moving in forward direction. This happens because when bus starts moving forward, lower part of the person begin to move with the bus whereas the upper part of the body tends to remain in rest due to inertia.

However, this variety of buses aren't just a figment of a fantasy writer's (I'm talking about J. K. Rowling) imagination, but did exist, but just not in the form that we've imagined. Presenting, the triple-decker bus! Built in 1932, the first triple-decker bus was made in Italy.

Heading to Los Angeles, your next stop is at BYD Auto Co., Ltd. for a ride on the BYD C10MS. At a height of 13.4 feet, the C10MS holds the title for the tallest bus in the world.

How much does a double-decker bus cost in the US? ›

The 81-seat double-decker bus costs about $1 million. The 57-passenger MCI motorcoach buses that are currently in the OMNIRIDE fleet costs about $600,000.

The United Kingdom has a triple standard for the double-decker bus: highbridge bus (urban Britain), lowbridge bus (countryside Britain) and 4 metres height coach such as the Neoplan Skyliner that can traverse Europe.

Other than the UK, there are double decker buses in Ireland; and in Germany, where they also make this monster: - A model offered by the aptly-named German consortium Unglaublich Grossbusfabrik (Incredible Big-Bus-Factory, or something like that).

In urban areas, you can only get off at marked bus stops. However, in rural areas with no fixed bus stops, our bus drivers will happily stop on request if it's safe to do so. Our biggest concern is your safety and the safety of the other customers and driver.

It depends on the configuration ordered by a transport company but a classic (short) city bus has about 30 seats and 70 places for staying (depends on a norm)but there Is often much less ppl in real operation. I haven't hard data but I would say, there is often about 50 ppl max.

The following items are identified by SED and DOT as unauthorized and not allowed - starting with the most obvious: hazardous materials, gasoline, poisons, explosives, radioactive materials, car batteries, animals, rodents, aquatic pets, insects, reptiles, large or bulky items that cannot safely fit on students' laps ...

Standing on the upper deck will cause the top deck of the bus to be heavier than the bottom deck. The centre of gravity will rise and the bus will lose its stability. When it makes a turn, the top deck will probably cause the whole bus to tilt dangerously (and fall, in the worst scenario).

The passengers travelling in a double-decker bus are allowed to stand on a lower deck, but not on the upper deck, because of the centre of gravity of the bus shift to some more height. it reduces the stability. It makes the passengers difficult to stand and makes them fall.

Double-decker buses have heavy weight attached to their undersides to lower the centre of . If an object is tilted it will topple over if a vertical line from its centre of gravity falls outside its base.

(Accessibility tip: If you're using a wheelchair (or other wheeled mobility device that is parked in a wheelchair position), push the yellow strip affixed to the seat next to you at the wheelchair position--this will notify the bus operator that someone at a wheelchair position needs to exit.)

Why do buses have Moustaches? ›

“State Transit is proud to be supporting Movember in their efforts to bring greater attention to the fight against prostate cancer, testicular cancer and male suicide." Movember Country Director, APAC, Rachel Carr said: “We're delighted that State Transit has gotten behind Movember in such a big way this year.

Ensure students stay in the driver's line of sight

Mandated in 26 states, and used in every state, the school bus crossing arm is an essential safety feature designed to prevent students from walking too close to the bus and being accidentally struck. Proven to improve student visibility and prevent accidents.

Rear-Engine, Flat-Nose Buses

They provide unobstructed entry for passengers. They're more lightweight than front-engines. They're much quieter than front-engines.

School bus seats are higher off the ground so that most opposing vehicles are below the kids' feet. The four-inch cushioned seats and high seat backs create a compartment for students in the event of an accident.

Passengers are not allowed to stand in a small boat because standing raises the centre of gravity of the boat, due to which line joining the centre of gravity and centre of earth may fall outside the base of the boat crossing the river. Thus, boat can topple and sink.

Priority seats on the bottom deck are best. Second best is the top deck, three rows from the front, on the aisle seat.

On jumping out of the moving bus, if one doesn't run their feet would suddenly come to rest but their upper body would still continue to stay in its state of motion and hence they tend to fall forward. But if the person runs in the direction of the bus for some distance, the body will remain in motion due to inertia.

This is due to inertia. When the speeding bus stops suddenly, lower part of the body comes to rest while the upper part of the body tends to maintain uniform motion. Hence, the passenger's are thrown forward.

This leads to an increase in the chances of the boat rocking as the torque offered by the wind, waves and other forces, also increases. This increased rocking can be potentially dangerous for the boat and all the passengers aboard. Therefore, the passengers in a boat are not allowed to stand up.

Wakeboarding and wakesurfing are similar in that they both feel a little bit like ocean surfing, but they are different. While a wakeboarder is towed behind a boat for the entire ride, in wakesurfing you only use the tow rope to get up on the board – and then let go and ride the wave.

Why were the passengers stunned? ›

iv They were stunned at the carelessness and behaviour of the young boy.

The safest seat in a school bus is generally in the middle, in an aisle seat on the right hand side, between the tires. It's safer if there's a head-on, side and rear-end collision. It is also less bumpy and jarring to the body. In addition, studies show that children are often injured approaching or leaving the bus.

Tipping over accidents.

Because double-decker buses are tall, box-shaped and have a high center of gravity, when they are involved in certain types of accidents they are more likely to tip over than other types of buses.

Inertia is the force that caused the person to fall forwards. This was discussed by Newton's first law of motion. Initially, the person was moving at the same speed as that of the bus. When the bus suddenly stops, the body of the person was still used to the motion.

Passengers are thrown outwards because of inertia of direction. If suddenly the breaks are applied passengers will be thrown forward, and if suddenly the bus is accelerated the passengers will be thrown backward.

After alighting from a moving bus, one has to run for some distance in the direction of bus in order to avoid falling.

Newton's I law of inertia states that an object will change its direction when a force is applied to it. Hence, when a bus takes a sudden turn the passengers are thrown outward. This is due to the inertia of direction.

We are standing in a bus and bus begins to move suddenly. We tend to fall backwards. This is because the sudden start of the bus brings motion to the bus as well as to our feet in contact with the floor of the bus. But the rest of our body opposes this motion because of its inertia.

When a bus starts suddenly,its passengers tend to fall backwards because due to their inertia, the passengers tend to remain in a state of rest even when the bus starts moving.
