Adaptive Traffic Flow Systems: Enhancing Safety and Efficiency through Advanced Technologies

This text explores innovative traffic flow systems that utilize robotic, sensory, and adaptive technologies to enhance roadway safety and efficiency. Key elements include various safety shutoff mechanisms, mobile readouts, and integration with existing infrastructure. Central to the discussion is the importance of monitoring traffic patterns and conditions, alongside the application of high-resolution data analytics and wireless communications. Emphasis is placed on the role of governmental and local entities in regulating and supporting the implementation of these modern traffic management solutions.

  1. GO-LIGHT

  2. glossary • Run-up • Trap • Node • Void, Empty Space • Pi • Pa • Service cycle • Sf • pgS • Tng • Dx • Safe Following Dist; Reaction Time • Space-time • FLOW • FLOW Pattern • Consolidation • Compression

  3. Algorithms • All resonate from V=d/t • V=d/t Differential • Speed Assignment • Vsa • Inertial (Mobile) • Safety

  4. Pi Digram

  5. Distance(time) vs Relative Distance (time)

  6. Three Types of F L O W mechanisms and a safety shutoff • Emplaced • Mobile • Robotic / Sensory Adaptive • Safety Shutoff

  7. Products • Emplaced readout • Whole number • High resolution • Mobile readout • Straight event based • Onboard Memory/ inertial nav. • Robotic Influenced (mind changer sequencer) • Sensor • For opposing traffic increases/decreases • For waiting traffic works with updated infrastructure (i.e. loops by signals) • For stragglers and turn-on • For manual programming inputs • Inclement conditions • Rush hours

  8. Components of products at signal • Sequencer • “PLC” that integrates with signal sequencer • “PLC” that piggybacks to signal sequencer, “slaves” through RS232 • Integer output (increments in whole numbers) • Frequency output • Up to thousands of outputs per second • Each output is “package” • Best ap = WIRELESS • Focused radio beam

  9. Products at Readout • Emplaced readout • At least 1 at node • 2 place numerical • With decimal bar • Graphic • More sophisticated semaphores, multiple readouts • Mobile readout • See “Audi” • 2 place numerical to compare to actual speed • Graphic • Up Green • down red or yellow • silver = sign • Sound

  10. EMPLACED • Uses changeable message signs for readouts • Runs through autonomous set

  11. EMPLACED

  12. MOBILE • Uses Wireless signal from sequencer to vehicle • Uses Onboard Readout • Alphanumeric comparison • Graphics • sound • Can include Inertial Nav.

  13. Readout Components • Calculator with two interrupted inputs • Input signal status (from frequency sequencer (base station”) “package” or “sentence” “What kind of signal am I and where am I at my period Pa” • Done thru RF • Wireless mesh and so on • Input location status • Done through GPS • “Enhanced” GPS • RF, mesh or the like • Works as inertial navigation system that is “updated • Works as calculator spurred by constant updating Status RF inputs and going in and out of interrupts to receive updated location status • Tied in with either speedometer or GPS supplied speed output to form inertial navigation • Vsa readouts calculate from position vs time left

  14. “Good Morning” • System woken by either RF proximity, • Or by comparison of actual GPS location against a GPS stored map

  15. Mobile RCR Basic Function

  16. Mobile Receiver

  17. Status Inertial Nav

  18. Location Inertial Nav

  19. RCR Embedded in Onboard Computer

  20. ROBOTIC Robotic Influenced (mind changer sequencer) • Sensory Based; Adaptive • For opposing traffic increases/decreases • For waiting traffic (being sensed by sometimes existing infrastructure (i.e. loops by signals) • For stragglers and turn-on • For manual programming inputs • Inclement conditions • Rush hours

  21. SAFETY • Go/No go • Established by conditional • Distilled for approaching random traffic

  22. Safety Flow Chart

  23. Lets Demonstrate • Say initial conditions of “Average” Installation • Run from programmable calculator

  24. Lets Demonstrate from Laptop • Get Xcell • Take and plot readings

  25. RANGE of APPLICATION • FLOW system is settable from “open speed limit” i.e. 75 mph on down to low speeds (20?) • With “standard” controls, minimum speeds in a FLOW system can be as high as 45% of the speed limit

  26. Laws • Traffic Signals takes precedence • Tng following ≥ 2 second space-time • Local in charge of (ownership of) settings • Minimum Factory Setting greater than 2 seconds space-time net close following

  27. Business / Marketing Establishment • Busses First. • Traffic Signal Owners also own readouts and sequencers • F, S, L Gov’t regulate readouts, i.e how often, what following distances are • Motorists buy mobile readout • *Auto companies supply them in cars? • Included in Navigator / Route-finder? • Initially “Radio Shack” modules?

  28. INCENTIVE What interest do we have in making them here?Why would there be incentive for Local support of Foreign Patents? • Local Building could provide for local income from taxes! • Locally made products that are intellectually protected offshore can provide for further increased income from taxes! • Motorist will like because they provide more mobility • Gov’t should like because • Reduces dependence on foreign oil • Reduces greenhouse gas and pollution
