Reminder… Did you do Section 3 Day 3 quiz?? Bring paper/pen/pencil and notebook Electronics are for instructional use with permission Did you do Section 3 Day 3 quiz?? No Excuses why you didn’t take Quizzes 1-6 before test day!! (Quizzes are worth 30% of grade) Attendance is MANDATORY!! (NO SLEEPING in class) All notes can be found on Harrisonburg’s staff website: http://staff.harrisonburg.k12.va.us/~tbutler/ If you are NOT taking notes in class, please be quiet and ask to use the restroom at the end of class

Day 4 Objectives The students will understand how to manage visibility, time and space The students will understand appropriate intersection search patterns The students will understand how to cross and join traffic at intersections The students will be able to define and explain ground viewing Related SOL: DE.4, DE.5, DE.6, DE.7, and DE.12

Managing Visibility, Time and Space 20- to 30-Second Search Area Search far ahead to identify potential conflicts Awareness Zone Objects in Path of Travel Limitations to Line of Sight Target Area 20- to 30-sec. 12- to 15-sec. 4- to 8-sec.

Managing Visibility, Time and Space 12- to 15-Second Search Area Search for Closed or Changing Path of Travel Identify an Alternate Path of Travel or a Safe Stopping Zone Identify objects that require a change in speed or direction Evaluate Open Zones to the Sides and Rear 12- to 15-sec. 20- to 30-sec. 4- to 8-sec.

Managing Visibility, Time and Space 4- to 8-Second Search Area Immediate Path of Travel Direct Response Area Stopping Zone and Following Interval 20- to 30-sec. 4- to 8-sec. 12- to 15-sec.

Searching 4-8 seconds ahead 4 seconds – represents the following distance 8 seconds area - provides for a safe stopping distance under most conditions 4-8 seconds

Maintaining Space/Visibility to the Front Three ways to control space in front of the vehicle: 1. Time your Arrival – adjust speed early to avoid unnecessary braking, stops, and to conserve fuel 2. Forward Placement at an Intersection – maintain a position that allows you to monitor the intersection 3. Following Interval -- control space while in motion to establish a space cushion and open line of sight

Intersections

Intersection Search Patterns Intersection Approach: Step 1 (Search) Identify intersection Identify controls Check rear areas Search for intersection problems

Intersection Search Patterns Intersection Approach: Step 2 (Evaluate) Scan path of travel 1st Scan all other areas Look for closed or changing frontal areas

Intersection Search Patterns Intersection Approach: Step 3 (Execute) Adjust speed Maintain lane position Stop behind crosswalk, or Proceed through open space area in Time

Straddle Lane Positions Create Space and Improve Visibility by Adjusting the Position of the Vehicle in the Lane Lane Positions – 1, 2, 3, 4, and 5 Within Lane Positions Straddle Lane Positions LP 4 LP 2 LP 1 LP 3 LP 5

Intersections Risk is increased at intersections controlled by stop signs when joining and/or crossing multi-lane traffic. No Parking

Intersections Controlled by Traffic Signals Check for the following Oncoming vehicles making a left turn Pedestrians and cyclists in crosswalk Cross Traffic

Intersections Controlled by Traffic Signals Make sure there is space available before moving into the intersection for a left turn.

Intersections Controlled by Traffic Signals Count to three before moving Why?

Intersections Controlled by a Yield Sign Important to judge the distance/speed of approaching traffic. Make sure there is ample space so that you may join or cross traffic safely

Crossing and Joining Traffic at Intersections Crossing or joining traffic traveling at high speeds require larger gaps when traveling at higher speeds.

Ample Space for Crossing Traffic At a brisk rate of acceleration, crossing a 2 lane roadway 30 feet wide requires a gap of about six or more seconds. For an approaching vehicle traveling 30 mph, it is 264 feet, or about a half a block. At 55 mph, the same vehicle would travel 528 feet.

Ample Space for Crossing Traffic 60 MPH=6sec/528 ft. 30 MPH=6sec/264 ft.

Ample Space for Right Turns If turning right into traffic traveling 30 mph, a gap of about 8 or more seconds, 352 feet, is needed. With traffic traveling 55 mph, a gap of about 11 seconds, 880 feet, is needed.

Ample Space for Right Turns 55 MPH=11 sec/880 ft. 30 MPH=8 sec/352 ft.

Ample Space for Left Turns Similar to right turns, but more complex problems exist because you must first cross the lanes of traffic traveling from left to right….when it is safe. Do not write this slide

Ample Space for Left Turns You need a gap of about 6 seconds to cross the 2 lanes moving left to right. If traffic moving right to left is traveling 30 mph, a gap of 14 or more seconds ,484 feet, is needed. With traffic traveling 55 mph, a gap of 17 or more seconds , 1130 feet is needed.

Ample Space for Turning Left 30 MPH = 14 sec/484 ft. 55 MPH = 17sec /1130 ft.

When Stopping Always check the rearview mirror when getting ready to stop Tap brakes to flash the lights to alert others

When Stopping Ground Viewing: You should be able to see the rear wheels of the car in front of you touching the ground.

Mirror Usage When Turning Check before any change of speed or position is made so that you can control rear and side space.
