17.2.3.1 Connectivity
Many suburban residential streets were designed to limit
c. To
accomplish this goal they were laid out to be disconnected. Lack of connectivity,
however, made it dif
through traf
cult for police and emergency vehicles to provide a quick
response. This condition generates excess travel that could be eliminated by making
the necessary connections of routes within residential areas as shown in Fig.
17.9
.
Connecting the missing links within residential areas can reduce the VMT (and
congestion) on connectors and arterial streets.
17.2.3.2 Continuity
Many collector streets and some arterial streets are discontinuous. The discontinuity
results in double loading of available streets by the displaced traf
c. The VMT
increases, as do turning movements and peak period congestion. This condition is
illustrated in Fig.
17.10
