  • Tollbooths

  • Entrance/exit ramps

  • Limited access

  • More lanes

  • 55-65 MPH

  • Minimum 45 mph

  • IPDE faster

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
Advantages to Expressway Driving

  • Designed for low-risk higher speed travel

  • Safer than other highways

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

  • check mirrors

  • check blind spot (just before moving over)

ACCELERATE!!!!


Steps for ENTERING expressway

Step # 4

  • Find TARGET (car) to follow

  • merge smoothly


Steps for ENTERING expressway

  • Step # 5

  • Cancel signal

  • adjust to speed of traffic






Woodfield shopping area Interstate 90 & 53



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

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


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

…signal, mirror, final head check left


Make any necessary speed adjustments
…make any necessary speed adjustments on ramp?

…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

d. Merging area

b. Ramp signal lights

e. Entrance on left

c. Acceleration lane


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

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

IPDE on ramp?

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

You will not be delaying faster traffic
You will not be delaying faster traffic on ramp?

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 merger. If you can, what is your best decision to avoid a conflict?

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 merger. If you can, what is your best decision to avoid a conflict?


  • Speed limits merger. If you can, what is your best decision to avoid a conflict?

    • 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 merger. If you can, what is your best decision to avoid a conflict?

    • 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 expressway page 236
Exiting merger. If you can, what is your best decision to avoid a conflict? 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! merger. If you can, what is your best decision to avoid a conflict?

Best Lane Choice: Middle/Right Lane

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