When you change lanes, or merge with another lane, you:

When merging onto a freeway, you should enter at or near the speed of traffic.

How To Merge Into Traffic

1. First, identify a gap between cars on the freeway where you can merge.
2. Then, continue increasing your speed until you reach the gap you selected.
3. Once on the freeway, adjust your speed to keep a cushion of space around your car.

1. Have the right of way.
2. Should first stop and check for cross traffic.
3. Need at least a four second gap in traffic.

The merging car is required to yield to traffic on the freeway. It’s not illegal for the car already on the freeway to continue forward without allowing the merging vehicle to enter. Be prepared to slow to let the other car in.

Steps for Successful Passing

• Scan for hazards, e.g., oncoming vehicles, vehicles approaching from rear, merging vehicles;
• Check for blind spots;
• Signal your intention and accelerate into passing lane;
• Accelerate quickly to an appropriate speed;
• Concentrate on the path ahead;
• Check the mirror for following cars.

The 50 most dangerous highways in the US

You are driving on a two-lane highway. The final decision whether to abort a pass or proceed to pass should be made just prior to: Reaching the vehicle you are passing.

Being Passed If a vehicle is passing you, or has signaled intent to pass, you should avoid accelerating and maintain your lane position to allow the vehicle to pass you. Do not accelerate or try to go faster to avoid being passed.

Yellow traffic signs stand for slowing down, driving with caution, or a general warning. It may be yellow, or yellow-green with black wording or symbols. This sign warns you about hazards or possible hazards on or near the roadway.

Drivers Ed Done Right Farm tractors, animal-drawn carts, and road-maintenance vehicles are not designed for high-speed travel and move slowly.

Traffic Signal Rules in India

It is always recommended to use the sidewalks (footpath) because you are safely separated from the automobiles. Where there is no sidewalk, you should walk facing the oncoming traffic. This means, In countries with left hand traffic system (like India), you should walk on the right side of the road.

Annual Average Daily Traffic

In some states, AADT of 50,000 may be considered high, while 100,000 may be the threshold in other states. As a guide, therefore, it is recommended that high-volume routes can be defined as those carrying traffic in excess of 50,000 AADT.

Annual average daily traffic, abbreviated AADT, is a measure used primarily in transportation planning, transportation engineering and retail location selection. Traditionally, it is the total volume of vehicle traffic of a highway or road for a year divided by 365 days.

Under the simple average method, AADT is estimated as the total traffic volume passing a point (or segment) of a road in both directions for a year divided by the number of days in the year. It requires volume for every day of the year.

How can I get a quick estimate of traffic volume on my highways without traffic counters or a speed trailer?

1. Daily traffic = C*F.
2. C = 15-minute count.
3. F = multiplier based upon area:
4. As an example, if the count is 106 cars in 15 minutes in a suburban area, the daily count would be 3,500 (106*33=3,498).

Annual Average Daily Traffic (AADT) is one of the most important parameters in transportation engineering. It is calculated by adding the total vehicle volume of a highway for a year divided by 365 days.

The actual (design) flow rate can be calculated by dividing the peak hour volume by the PHF, 743.6/0.85 = 879 PCU/hr, or by multiplying the peak 10 minute volume by six, 6 × 146.5 = 879 PCU/hr.

Passenger Car Equivalent (PCE) or Passenger Car Unit (PCU) is a metric used in Transportation Engineering, to assess traffic-flow rate on a highway.

Estimation of Passenger Car Unit (PCU) values is important for traffic capacity analysis, level of service measures, signal design and coordination, saturation flow rate determination and development of traffic flow models.
