For the ITE yellow change interval formula to work, how fast must you go to make it to the intersection before the light turns red?

 

=

 

6Slide7

For the ITE yellow change interval formula to work . . .

You must go the maximum allowable speed or faster from the critical point to the intersection entry point.

Slowing down is forbidden.

Which is the reason why people beat the light.

You must know exactly where the critical point is.

What is the equation for a turning vehicle that slows down with constant deceleration from the maximum allowable speed

at the critical point to the to

at the intersection?

What else should ITE take from the physics tool box?

Engineering Tolerances for purposes of law enforcement

Acceptance of only Physical Solutions. Only physical solutions are engineering practices.
