Transportation Engineering and Management Moving People and Goods

Transportation Engineering and Management Moving People and Goods through Air, Water and Land Highways Trains Tunnels Rails Bicycles Boats Planes

Transportation Engineering 1 in 100 injured each YEAR in auto accidents Over 40, 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

Level Of Service Engineering Theory meets Public Opinion Your parents tax money is used to move people and goods. Politicians not Engineers chose projects. Communication of complex ideas is your resopnsibility.

Levels of Service LOS A LOS B Reasonably free flow Ability to maneuver is only slightly restricted Effects of minor incidents still easily absorbed From Highway Capacity Manual, 2000 Free-flow operation

Levels of Service LOS C LOS D Speeds decline slightly with increasing flows Density increases more quickly Freedom to maneuver is more noticeably limited Minor incidents create queuing From Highway Capacity Manual, 2000 Speeds at or near FFS Freedom to maneuver is noticeably restricted Queues may form behind any significant blockage.

Levels of Service LOS E LOS F Breakdown in flow Queues form behind breakdown points Demand > capacity From Highway Capacity Manual, 2000 Operation near or at capacity No usable gaps in the traffic stream Operations extremely volatile Any disruption causes queuing

LOS at Signalized Intersections LOS Signalized Intersection A ≤ 10 sec B 10 -20 sec C 20 -35 sec D 35 -55 sec E 55 -80 sec F ≥ 80 sec

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

Pavement Management and Evaluation Techniques Heavy Vehicle Simulator (HVS)

What is it (THE HVS)? Accelerated pavement testing 20 yrs of deterioration in 3 months http: //www. youtube. com/watch? feature=player_detailpage&v=b LQ 68 j_t. Kg. A

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 Eliminates traffic congestion at toll plazas. Achieved by scanning bar codes, license plates, or infrared communication systems. We’ve got him now!!

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 1/3 rd 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 1970 s 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

Mass Transit Technologies Maglev Trains float on superconducting magnetic rails

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