Expressway Driving


Characteristics of Expressway Driving

Roadway

Speed

  • Interchanges

  • No cross traffic

  • Median

  • Tollbooths

  • Entrance/exit ramps

  • Limited access

  • More lanes

  • 55-65 MPH

  • Minimum 45 mph

  • IPDE faster

  • Predict sudden stop


Characteristics of Expressway Driving

Other Users

No pedestrians

Trucks

Motorcycles

Construction

Emergency vehicle

Signs & Signals

  • Green guide signs

  • Merge

  • No traffic signals

  • Interstate signs


Advantages to Expressway Driving

  • Designed for low-risk higher speed travel

  • Safer than other highways

  • No cross traffic

  • Median or barrier separates oncoming traffic

  • Pedestrians & slow moving cars are not allowed

  • Wide shoulders = good escape paths

  • Signs help anticipate conditions early


SafeDrivingStrategies

  • Collisions can be more serious

  • Know where you are going

  • Obey speed limit or common speed

  • Build experience gradually

  • Give full attention to driving task

  • Cooperate with other drivers


3 Parts of Entrance Ramp

See picture in textbook page 225

1. Entrance Ramp

2. Acceleration Lane

3. Merging Area


Steps for ENTERING expressway

Step # 1

Entrance you want ?

Is it an entrance?


Steps for ENTERING expressway

Step # 2

  • Check zones

  • Signal

  • Check rearview mirror and blind spot


Steps for ENTERING expressway

Step # 3

  • increase speed

  • check mirrors

  • check blind spot (just before moving over)

ACCELERATE!!!!


Steps for ENTERING expressway

Step # 4

  • Find TARGET (car) to follow

  • adjust speed

  • merge smoothly


Steps for ENTERING expressway

  • Step # 5

  • Cancel signal

  • adjust to speed of traffic


Randall Rd. and Interstate 90

Double turn lane to go EAST on 90 off Randall Rd.

One example of Entering an Expressway


What is the purpose of the first head check…early on ramp?

Check the volume of traffic and their speed…

(so you’ll know how fast to accelerate)


Look for a space to merge in...

What is the purpose of the second head check as the ramp begins to straighten?


…you are now building up speed- you should also…at this point:

…signal, mirror, final head check left


…make any necessary speed adjustments

…but what will you do if you can not get over because other vehicles are preventing your merge?


#5 What other problems might you encounter entering the expressway?

a. ramp

d. Merging area

b. Ramp signal lights

e. Entrance on left

c. Acceleration lane


-- stay back and let him merge…then you can quickly accelerate & complete your merge

What if there is a slow moving truck in front of you getting ready to merge?


Short merging area, sharp curves


Shared entrance and exit

Best Lane Choice: Middle/Right Lane

How about an entrance on the left??


Best Lane Choice: middle or right lane


Scott’s Law (Move Over Law)


IPDE

  • Identify—drivers have longer sight distance, MUST identify volume of traffic, signs & signals EARLY


Lane ChoiceRead section on page 230


You will not be delaying faster traffic

Best Lane Choice: Middle/Right Lane

If you will be driving slower, why is it best to stay in the right lane?


You are in the right lane and predict a conflict with this merger. If you can, what is your best decision to avoid a conflict?

Change lanes

Other options: speed up or slow down


Stay away from mergers

If you are moving with the flow of traffic, why is it best to drive in the center lane most of the time?


Sometimes there are additional merges to deal with


  • Speed limits

    • Minimum speed limit

      Driving too slowly can be dangerous on an expressway, highways have a set lowest speed

    • Common speed

      Drive at the common speed used by most drivers so you can blend with expressway traffic, sometimes common speed is higher than maximum speed


  • Lane changing on expressway

    • Steps for making lane change (page 233)

      Change one at a time, check mirrors, check blind spot, if path is clear then accelerate and move to next lane, cancel signal

    • Problems with lane changing—see pictures on page 233

      Two cars could be moving into the same open space, traffic in lane you are moving into may be going much faster


Exiting Expresswaypage 236

STEPS:

  • at least ½ mile ahead of exit move into the lane that leads to exit, do not reduce speed until you are in deceleration lane

  • move into deceleration lane, cancel signal

  • flash brake lights to warn drivers behind you are slowing, check rear zones

    4. identify ramp speed, check your speed, predict a yield sign, a stop sign or signal light at end of exit


Make a lane change right!

Best Lane Choice: Middle/Right Lane

If this driver wants to get off on Palatine Rd. what should they be doing ASAP?


We want to exit at the upcoming exit but what else do we need to look for?


You do not want to exit at Kirchoff Road… what must you do here?

Lane change


Preparing to exit at Randall Rd


A closer look at signs and roadway markings


If we are exiting here what should we be doing now?


If we are in the left 2 lanes can we still exit?
