Chapter 14: Driving in City Traffic Karime Bastida A1

14.1 Adjusting to City Traffic

Traffic Complexity:

  • Driving in the city will really test your skills.
  • Factors will come in place that will block your path of travel.
  • When driving you will have to use the IPDE Process which will take time.
  • Conflicts may arise at the same time and you will have to find a solution to all.
  • When you have a hazard and you cannot increase the following distance you will have to increase the following distance or you will have to change your lane position.
  • Slowing down or stopping will give you time to solve the conflict.

Using the IPDE Process:

  • Give all your attention to avoid conflicts and distractions
  • Some drivers will increase the risk by challenging other drivers
  • Driving aggressively is a criminal offense
  • Control aggressive driving situations by avoiding them
  • Identify: Check searching ranges
  • Use visual skills
  • Check line-of-sight restrictions
  • Predict: Gain time to respond
  • Predict where conflicts will happen
  • Decide: Be ready to communicate
  • Adjust car position
  • Use distance correctly
  • Execute: Be ready to make smooth low-risk maneuvers

14.2 Following & Meeting Traffic

Following Traffic

  • 3 second Following Distance: Gives you a safe distance between you and the car ahead of you in normal driving conditions.
  • Works well at all speeds
  • Works well at all driving conditions
  • Only protects you from crashing with the car ahead of you
  • Not total stopping distance that you need to avoid an object at rest
  • Add more following distance if the weather is not good
  • Stay Alert: Look over, through, and under the car you are behind from
  • You can see brake lights on the reflection of a wet pavement under the car
  • Try to think what the driver in front will do when changing zones
  • Be careful in areas where sudden stops can happen

Tailgaters

  • Tailgates: Following to closely behind a car
  • If you need to stop fast the driver will rear end you
  • Tailgating drivers think they have enough time to stop
  • They also think they can make you go faster
  • Managing tailgaters: You can take these steps when being tailgated
  • Increase following distance, if you need to stop do it slower
  • Move a little to the right so the tailgater can see ahead
  • Signal early for any actions, flash brake lights to warn the driver that you intend on slowing or stopping
  • In bad occasions change lanes or pull out of the traffic

Meeting Traffic

  • When a driver crosses over the line react quickly
  • Knowing how to handle a situation like that before will help give you enough time to react.
  • Avoiding conflicts: If a car is coming towards you take these steps
  • Slow down until the other driver can return to the correct lane
  • Turn on or flash your headlights and blow your horn to warn the other driver
  • if open move to the right front zone to give the driver more room

14.3 Managing Space in City Traffic

  • In city traffic there are things you will need to respond to
  • Unfamiliar streets
  • Line-of-sight restrictions
  • Narrow lanes
  • Heavy traffic
  • Always have a positive and alert attitude
  • Look ahead one block or more

Approaching Traffic Signals

  • Look around to find traffic signals
  • You will have more time to respond by looking at them earlier
  • If a light is red slow down and be ready to stop
  • If the lights on the streets are working at the same time you can drive at or near the speed limit for blocks
  • Look for DON'T WALK pedestrian signals that start to flash
  • Look for a pedestrian countdown signal number below 10 seconds
  • Those signals warn you that the light is stale (will change soon) and you have to decide if you have time to turn or not
  • Your decision will depend on the distance between the intersection and your speed
  • NEVER speed up to to get to a green light before the change
  • Any speed you are going at there will be a point-of-no-return (point where you need to start braking if stopping at an intersection)
  • Covering the brake: Maintaining a normal speed can be done when you are going to a stable problem free traffic place
  • To get ready to stop you need to cover the brakes take your foot of the accelerator pedal and hold it over the brake pedal.
  • This technique can be used when you feel a problem will arise and to help avoid a collision.
  • When you cover the brake don't ride the brake or rest your foot on the brake pedal
  • If you do your brake heats up and they wear faster
  • Your brake lights will also stay on

Selecting the Best Lane

When you drive in multilane traffic you will use different lanes at different times.
  • Left lane is usually for the faster moving traffic
  • Traffic can be help up by drivers waiting to turn left
  • Choose the lane where traffic is flowing the smoothest
  • Overtaking and Passing: Trying to pass in a city can be dangerous
  • Be aware for pedestrians, cross traffic, signals, and line-of-sight restrictions
  • Sometimes you might need to overtake (pass a car ahead)
  • If you overtake a car on a two way street you need to do it carefully and legally
  • It is illegal to pass at intersections or over double yellow lines located in the center
  • Use the lane changing procedure to overtake cars
  • Signal and then return to your lane when both headlights or the car you passed can be seen inside your rearview mirror
  • Special Traffic Lanes: To help move traffic many cities made lanes for buses and carpool drivers.
  • Drivers who travel alone have to use the regular more crowded slower moving lanes
  • If you drive together in buses more fuel and time will be saved
  • Pollution and parking problems will be reduced

14.4 Special City Situations

Driving on Two-Way Streets

  • Most roadways are two-way streets with one lane going in each direction
  • Many intersections in a city do not have traffic controls
  • You don't know what other drivers will do at blind intersections (where your view of traffic is minimal
  • If you have a left turn at a blind intersection you must yield

Driving on One-Way Streets

  • More traffic with less conflicts
  • Identifying One-Way Streets: See if there is a ONE WAY sign posted
  • All moving traffic and parked cars are pointing in the same direction
  • Broken white lines that separate lanes and traffic signs in the same directions
  • Entering One-Way Streets: To make a left position yourself to the nearest left lane
  • If driving on a one way for a distance try to pick a lane that is away from parked cars
  • A parked car could pull out anytime
  • If you are going to turn position your car ahead of time
  • Leaving One-Way Streets: When turning out of a one-way street turn to the nearest lane going your way
  • On some one-way streets the outside lanes may be for turns only
  • You will need to make changes when a one-way street turns into a two-way street
  • Unexpected Situations on Crowded Streets: If a car is going the wrong way on a one-way street honk the horn and flash the lights
  • Maintain an ordered visual search pattern
  • If drivers have a green light they must stop for pedestrians
  • Angle and parallel parking is allowed on most streets
  • At first sign of movement from a pedestrian or car change lanes
  • Roundabouts cut crash injuries by up to 75 percent
