T-5.2 Space Management System Components Search for objects or conditionsSearch for objects or conditions Evaluate the path ahead for alternate paths of travelEvaluate the path ahead for alternate paths of travel Prepare to make adjustments in speed and/or positionPrepare to make adjustments in speed and/or position Searching includes:Searching includes: –Where to search –When to search –How to search –What to search for

T-5.6 Managing Visual Searches 20 to 30 Second Visual Search Area20 to 30 Second Visual Search Area –Search as far ahead as possible to identify potential conflicts Objects in Path and Areas of Limited VisibilityObjects in Path and Areas of Limited Visibility Limitations to Path of Travel and Line of SightLimitations to Path of Travel and Line of Sight 12 to 15 Second Visual Control Area12 to 15 Second Visual Control Area –Identify Objects or Conditions That Require a Response or Continuing Attention –Look for Closed or Changing Path of Travel
8
T-5.7 Managing Visual Searches 8 to 12 Second Response Area8 to 12 Second Response Area –Identify an Alternate Path of Travel and Safe Stopping Zone –Evaluate Open Zones to the Side and Rear 4 to 8 Second Directed Response Area4 to 8 Second Directed Response Area –Other than Detecting Color or Movement, the Brain Receives Definitive Information (Images) from the Eyes Only When the Eyes Fixate –The Eyes Fixate Only on That Which the Brain (through practice and experience) Directs Them To Fixate
9
T-5.8 Determining Following Intervals A two to three second following interval is intended to provide time to steer and is acceptable only in heavy traffic flows. It provides time to brake to a stop only if you are monitoring the actions of drivers 8 to 12 seconds ahead in your path of travel. In most instances, it necessitates steering to alternate escape path in an emergency.

T-5.23 Determining Passing Time/Space Needs 40 mph = 60 feet 1-2 second return to lane 74 ft/sec @ 50 mph 3 lengths of car per sec may take 8 to 10 sec to pass another car 2-3 seconds start pass 40 mph = 120 ft
25
T-5.24 Passing Needs Constant: 1 mph = 1.4667 or 1.5 feet per second (fps) Time to pass = distance traveled to complete pass, divided by difference in distance traveled per second by each vehicle, 30 mph = 45 fps 40 mph = 60 fps 60 ft-45 ft = 15 ft 2 sec. Following Distance = 120 ft. 1 car length= 15 ft. 1 sec. Lead= 60 ft. Total additional distance traveled = 195 ft. Time needed to pass: 195/15 = 13 sec. Total distance traveled: 13 sec. X 60 fps. = 780 ft

T-5.25 Passing Considerations Larger VehiclesLarger Vehicles –24 seconds to pass tractor trailer rig (90 feet) traveling @ 50 mph, when passing @ 60 mph –2160 feet needed to complete 24 second pass Oncoming VehiclesOncoming Vehicles –Approaching vehicle travels 2160 feet @ 60 mph –Total clear distance needed to pass becomes 4320 feet when approaching vehicles exist Daylight Headlight Use CriticalDaylight Headlight Use Critical
27
T-5.26 Passing Procedures Prepare to pass –Position yourself two to three seconds behind the vehicle you want to pass –Check mirrors and oncoming traffic –Check ahead for safe passing distance –Signal your intention
28
T-5.27 Passing Procedures Overtake the ongoing carOvertake the ongoing car –Signal your intention and accelerate into passing lane –Accelerate quickly to an appropriate speed –Concentrate on the path ahead –Check your mirror for following cars Return to laneReturn to lane –Check your rear-view mirror for the front of the car you are passing –Signal your intention –Change lanes and maintain speed –Cancel turn signal
