As I am sure you know, most of the existing study references out there make reference to the previous NCEES list of design books (ex. they reference the previous 2003, not the current 2009 MUTCD). Thus, I think the requirements you list, are from the 2003 MUTCD (see copy/past below). You should be able to find the 2003 MUTCD on-line for free at FHWA's website. Let me know if you need a link.
Section 4C.05 Warrant 4, Pedestrian Volume
Support:
The Pedestrian Volume signal warrant is intended for application where the traffic volume on a major street
is so heavy that pedestrians experience excessive delay in crossing the major street.
Standard:
The need for a traffic control signal at an intersection or midblock crossing shall be considered if an
engineering study finds that both of the following criteria are met:
A. The pedestrian volume crossing the major street at an intersection or midblock location during an
average day is 100 or more for each of any 4 hours or 190 or more during any 1 hour; and
B. There are fewer than 60 gaps per hour in the traffic stream of adequate length to allow pedestrians
to cross during the same period when the pedestrian volume criterion is satisfied. Where there is a
divided street having a median of sufficient width for pedestrians to wait, the requirement applies
separately to each direction of vehicular traffic.
The Pedestrian Volume signal warrant shall not be applied at locations where the distance to the
nearest traffic control signal along the major street is less than 90 m (300 ft), unless the proposed traffic
control signal will not restrict the progressive movement of traffic.
If this warrant is met and a traffic control signal is justified by an engineering study, the traffic control
signal shall be equipped with pedestrian signal heads conforming to requirements set forth in Chapter 4E.
Guidance:
If this warrant is met and a traffic control signal is justified by an engineering study, then:
A. If at an intersection, the traffic control signal should be traffic-actuated and should include pedestrian
detectors.
B. If at a nonintersection crossing, the traffic control signal should be pedestrian-actuated, parking and other
sight obstructions should be prohibited for at least 30 m (100 ft) in advance of and at least 6.1 m (20 ft)
beyond the crosswalk, and the installation should include suitable standard signs and pavement markings.
C. Furthermore, if installed within a signal system, the traffic control signal should be coordinated.
Option:
The criterion for the pedestrian volume crossing the major roadway may be reduced as much as 50 percent if
the average crossing speed of pedestrians is less than 1.2 m/sec (4 ft/sec).
A traffic control signal may not be needed at the study location if adjacent coordinated traffic control signals
consistently provide gaps of adequate length for pedestrians to cross the street, even if the rate of gap occurrence
is less than one per minute.
