When a vehicle receives an alert message (see Figure 2(b)),
it verifies its original route to check if it goes through the
accident point. Therefore, a new route is calculated to avoid the
accident point. However, when vehicles 3, 4 and 6 receive the
message, they verify that their original route will pass through
the accident point, but there is no alternative route to avoid
the accident point.
