Presentation Transcript


Transportation Engineering and Management

  • Moving People and Goods through Air, Water and Land

    • Highways

    • Trains

    • Tunnels

    • Rails

    • Bicycles

    • Boats

    • Planes


Transportation Engineering

  • 1in 100 injured each YEAR in auto accidents

  • Over40,000 DEATHS yearly in auto accidents

    • Half Related to Alcohol

    • Is this the Engineers Responsibility?

  • And Florida Was # 1 in traffic fatalities each year

  • What can YOU do to HELP?

  • Move People and Goods SAFELY


Roadway Speed Kills -10 or + 15


Team Building

  • Transportation Engineers and Planners MUST work as a team.

    • Wal-Mart on Palm Bay Road Produced a 30 minute traffic jam every work day

    • Florida was growing faster than “we” can improve its infrastructure

    • Sacrifices must be made for the future to be better

  • Florida’s Transportation Engineers must be better than those in the other 49 states


Transportation Controls Economy

  • Movement of People and Products

  • Delays Cost Serious $$$$

  • Interstate Costs Per Mile exceed $10 million


Technology Can Really help

  • Real time data produces real time engineering solutions  let’s finish what we started

    • Speed controls based upon traffic volumes and roadway capacities

    • Weight monitoring used to measure actual stress and strain and compare to design values

  • Unlimited Possibilities exist

  • Civils, Mechanicals, Electrical, Computer working together with Planners


Composite Causeway

  • 5540 ft long

  • Lightweight fiber reinforced bridge

  • 1/3 wt of conventional concrete

  • 100 year design life


Quake-Proof Crossing

  • 75 Year old Bay Bridge

  • Oakland California

  • 1989 Earthquake

  • 280,000 VPD

  • Suspension Bridge

  • 2050 foot span


Swiss Tunnel

  • Connects Germany to Italia Through Swiss Alps

  • Moved 31 million cubic yards of material

  • High Speed Rail

  • Zurich to Milan part

  • Cut 90 minutes


Level Of Service

Your parents tax money is used to move people and goods.

Politicians not Engineers chose projects.

Communication of complex ideas is your resopnsibility.

Engineering Theory meets Public Opinion


LOS A

Free-flow operation

LOS B

Reasonably free flow

Ability to maneuver is only slightly restricted

Effects of minor incidents still easily absorbed

Levels of Service

From Highway Capacity Manual, 2000


LOS C

Speeds at or near FFS

Freedom to maneuver is noticeably restricted

Queues may form behind any significant blockage.

LOS D

Speeds decline slightly with increasing flows

Density increases more quickly

Freedom to maneuver is more noticeably limited

Minor incidents create queuing

Levels of Service

From Highway Capacity Manual, 2000


LOS E

Operation near or at capacity

No usable gaps in the traffic stream

Operations extremely volatile

Any disruption causes queuing

LOS F

Breakdown in flow

Queues form behind breakdown points

Demand > capacity

Levels of Service

From Highway Capacity Manual, 2000


LOS at Signalized Intersections


Do you think the General Public could understand LOS?

  • No engineering skills

  • No Math Skills

  • No Science Skills

  • Hard Working

  • Raising Families

  • Backbone of Country


Technology

  • Impacts on Roadway

    • Sensors

    • Cameras

    • Computers

  • Impacts on Traffic

    • Air Bags

    • Antilock Brakes

    • Cameras for LOS


Heavy Vehicle Simulator (HVS)

Pavement Management and Evaluation Techniques


What is it (THE HVS)?

http://www.youtube.com/watch?feature=player_detailpage&v=bLQ68j_tKgA

  • Accelerated pavement testing

  • 20 yrs of deterioration in 3 months


History

  • South Africa 1980 – 4 VHS fleet

  • 3 new Mark IV’s

  • Each Cost over $2,000,000


Hydraulic Loading on Wheels

Single or dual test wheel

Wheel loads 7-45 kips

Speeds up to 8 mph

20 ft test beam


Environmental Controls

Temperature

Moisture


Mobility

  • Can move between test sections under its own power.

  • Should be towed over long distances.


Virginia's Smart Road Project


Location of Smart Road


Smart Road Features

Rain Towers

Sensors


Weather Control System


Hot-Mix Asphalt Strain Gages

Aggregate Dynamic Strain Gages

Vibrating Wire Static Strain Gages

Pressure Cells

Thermocouples

(TDR) probes

Liquid Level Gage


Intelligent Transportation Systems


What is it: ITS that is?

  • Program designed to manage transportation

    • vehicles

    • routes

    • loads

  • Brought about by traffic congestion (and partly by homeland security)


ITS

  • Intelligent Transportation Systems include:

    • Floating Car Data

    • Inductive Loop Detection

    • Video Vehicle Detection

    • Electronic Toll Detection


Floating Car Data

  • Determine traffic congestion using wireless mobile phones

  • Triangulated signals to achieve location

  • Very accurate in urban areas

  • In rural areas less mobile phones means less accurate


Inductive Loop Detection

  • Detects magnetic fields from vehicles as they pass over magnetic sensors in the road

  • Gathers traffic information to analyze congestion

  • Also used to detect vehicles weight, length, and speed

Hey Computer that’s Cosentino’s Ferrari


Video Vehicle Detection

  • Simply way to measure traffic flow and incident detection.

  • Uses simple cameras to obtain vehicle speeds, lane occupancy, and vehicle counts.

  • Also used for wrong way vehicle alarms and stopped vehicle detection.

Hey Camera Cosentino is going the wrong way again


Electronic Toll Collection

We’ve got him now!!

  • Eliminates traffic congestion at toll plazas.

  • Achieved by scanning bar codes, license plates, or infrared communication systems.


Transportation Engineering Fiber Optics and Roadway Testing


Today Civil Engineers, Architects and Planners work together to convince the public that better transportation is needed


Tomorrow ALL Engineers, Architects, Planners & Computer Scientists will be working together to convince the Public that SAFER and FASTER Transportation is Possible


Current Conditions

  • Half of our Highway System is rated poor to fair

  • 187,000 or 1/3rd of the 576,000 bridges are deficient

  • Bridge inspection

    • simple visual inspection

      • Can’t see steel in concrete

      • Can’t see steel below paint

      • Takes one week to inspect one bridge

      • It is dangerous

    • supported with diagnostic equipment.


Advantages of Fiber Optics

  • Small components can be placed anywhere

  • Measure stress, strain, temperature

  • Multiple Sensors can be placed on ONE line

  • Relatively inexpensive especially compared to millions spent on roadways

  • Immune to Electromagnetic Interference

    • I’ve got a funny story for you!!!


Example of Current Project

  • 120 fiber-optic sensors installed on steel bridge on Interstate 10 in Las Cruces.

  • Built in the 1970s and known to suffer from numerous fatigue cracks.

  • Instrumented bridge is capable of detecting and counting all standard-class vehicles and measuring their speed and weight


Maglev Trains float on superconducting magnetic rails

Mass Transit Technologies


In 2005, Hurricane Ivan destroyed part of I-10 near Pensacola Florida causing a 300 mile detour.
