A Method for Traffic Calming Using Radio Transmitter

Table 2

The speed data summary in different scenarios.

Location
Upstream area (the message is transmitted)	47	139	92	93	110	−16.6	−18	−24
Downstream area (the message is transmitted)	42	113	75.4	75	86
Upstream area (no message is transmitted)	50	88	68.5	68	76	0.29	0	2
Downstream area (no message is transmitted)	45	100	68.8	68	78

= minimum speed, = maximum speed, = mean speed, V₅₀ = 50th percentile speed, V₈₅ = 85th percentile speed, = difference of mean speed, = difference of 50th percentile speed, and = difference of 85th percentile speed.
