Title: Transportation Safety


1
Transportation Safety
  • Foundations of TDL
  • Mr. Brachle

2
Objectives
  • Introduce students to the TDL Career Cluster
    Transportation Systems/Infrastructure Planning,
    Management, and Regulation
  • Civil Engineering (Transportation Engineering)
  • (Content Standard 1)
  • Introduce Students to Transportation Safety
    Concepts
  • (Content Standard 2 and 3)

3
Transportation Case Study
  • The objective of this study
  • Analyze the current speed compliance ratio of
    traffic.
  • How many people do not comply with the speed
    limit on this stretch of road?
  • Generate a viable solution targeted to slowing
    down traffic and making this stretch of road
    safer for drivers and pedestrians.
  • Are current traffic speeds unsafe?
  • If they are unsafe, what can we do to slow down
    traffic in a safe way?

Transportation Safety Background
  • More than 3 million transportation-related
    injuries a year (nationwide)
  • Societal cost 231 billion a year
  • Loss to Nebraska 2 billion a year
  • Motor vehicle crashes account for 40 of all
    16-18 year old deaths in the US.

6
Transportation Safety Background
  • In Nebraska, 256 people were fatally injured in
    traffic accidents in 2007.
  • Downward Trend

7
Transportation Safety Background
  • As of July 3rd, 2008
  • 98 Fatalities
  • 84 in Rural Areas
  • 14 in Urban Areas
  • Compared to the 2004-2007 average
  • Fatalities are down 23 so far this year in
    Nebraska

8
Transportation Case Study
  • We are going to do a case study on a stretch of
    road just west of Bryan HS

48th street between Glasgow Ave and Giles Road
9
Transportation Case Study STEP 1
  • DATA COLLECTION
  • Using a stopwatch, time the cars as they pass
    between the two landmarks.
  • Landmarks will be given on next slide
  • Record your times for each car on the worksheet
    provided. (Vehicle Time Worksheet)

10
Transportation Case Study STEP 1
  • The land marks are
  • The pine tree just to the right of the house
  • The sign by the white building

13
What Time Did You Get?
  • Time between the two landmarks
  • 2.45 Seconds

14
Transportation Case Study STEP 2
  • CALCULATE THE SPEED
  • Now that we have our data, we need to find the
    speed of the cars in Miles per Hour.
  • Use the equation for speed
  • Speed Distance (Miles) / Time (Hours)

The time it takes for the cars to travel that
distance
The distance the cars travel
15
Transportation Case Study STEP 2
  • We need to convert FEET per SECOND to MILES per
    HOUR
  • There are 5,280 feet in a mile
  • There are 3,600 seconds in 1 hour

16
Transportation Case Study STEP 2
  • First, find the distance the car has traveled in
    miles
  • 1 foot 0.00018939 miles (1 / 5,280)
  • Number of feet the car traveled x .00018939
    Distance

17
Transportation Case Study STEP 2
  • Landmark Distance

163 Feet
Distance 163 x .00018939 Distance .03087057
Miles
18
Transportation Case Study STEP 2
  • Now that you have converted the distance from
    feet to miles, lets convert the time from
    seconds to hours
  • Insert the time you recorded in seconds into the
    equation
  • Number of seconds over 3,600

Number of Seconds 3,600
TIME (in hours)
2.45 Seconds / 3,600 .00068055 Hours
19
Transportation Case Study STEP 2
  • Now lets insert the TIME and DISTANCE into the
    Speed Equation

Speed (MPH)
DISTANCE TIME
20
Transportation Case Study STEP 2
  • TIME .00068055 Hours
  • DISTANCE .03087057 Miles

45.36 MPH
.03087057 Miles .00068055 Hours
Speed Limit 35 MPH
21
Transportation Case Study STEP 3
  • You and a partner will spend 20 minutes
    collecting data on this stretch of road.
  • You will time 10 different cars and calculate
    their speeds
  • Use worksheet provided

22
Transportation Case Study STEP 3
  • Once finished calculate the Compliance Ratio
  • Give the percent of vehicles going faster than
    the posted speed limit (35 MPH)
  • ( of speeders / 10) x 100 percent of speeding
    vehicles (Compliance Ratio)

23
Transportation Case Study STEP 4
  • Do we have a problem on this stretch of road?
  • DISCUSSON
  • What are the traffic laws in this area?
  • Speed Limit during SCHOOL?
  • What is or is not located on or around this
    stretch of road that may increase traffic speed?
  • Do you think that the low speed limit through
    here is important or should it be increased?

24
Transportation Case Study STEP 4
  • Using the internet, you and your partner will
    research possible solutions to slow down the
    traffic.
  • Stop Light
  • Traffic Calming Device
  • More Enforcement
  • Speed Bumps
  • Create a power point presentation to showcase
    your solution.
