For any combination of lane group

movements during a particular phase, one of these lane groups will control the

necessary green time for that phase. This is referred to as the ……………………. 

As a rule, cycle lengths in excess

of ………… minutes should be used only in exceptional circumstances.

The sum of the flow ratios for the

critical lane groups can be used to calculate a suitable ………

Applying a single PHF determined

for the intersection as a whole will result in more reasonable analysis

volumes.

A ………….. is created for the driver

if a safe stop before the intersection cannot be accomplished and continuing

through the intersection at a constant speed (without accelerating) will result

in the vehicle entering the intersection during a red indication. 

The walking speed of pedestrians,

is usually assumed as ……………

The

service measure (the performance measure by which level of service is assessed)

for signalized intersections is …………..

One of the biggest influences on the

arrival pattern of vehicles at each approach to the intersection is the level

of signal coordination along the roadway.

Progression quality is expressed as

the proportion of vehicles arriving at an intersection approach while the

signal indication is red for that approach. 

If

no initial queue is present at the start of the analysis period, the ……….. term

of the delay is simply set to zero.
