Turning Movement Counts:  These manual counts are required when the principal neighborhood traffic problems result from through traffic.  They will be conducted at intersections that serve as gateways to the neighborhood.  In most circumstances, they can be restricted to the peak travel hours (7:00 – 9:00 a.m. and 4:00 – 6:00 p.m.).

 Origin-Destination (O-D) Studies:  O-D studies will be conducted when the basic traffic problem relates to excessive cut-through traffic on a particular residential street, or when the problem relates to truck movements through the area. ..It is necessary to use a sufficient number of surveyors to observe all gateways to the neighborhood simultaneously, if a full understanding and documentation of the through traffic problem is to be gained.

 The likelihood that application of traffic calming measures to a residential area will have negative impacts, as well as positive consequences, suggests that existing problems will have to be judged as rather severe (by the neighborhood residents) for any consensus to be reached as to the acceptability of traffic calming plans.

 Turn or Entry Prohibitions  Description:  Used to prohibit particular turning movements onto local or collector streets.  Turn or entry prohibitions seek to reduce traffic volume, particularly cut-through volume traveling through local neighborhood streets.

 The old definition of the project impact area as being a 300 feet radius around a proposed project has been described by some citizens as somewhat arbitrary. The area needs to be large enough to cover the citizens directly impacted by the project, but it also must consider that traffic calming is intended to address the needs of the neighborhood and not those of through traffic.
