Traffic reversal on principal roads leading inland from Myrtle Beach and Hilton Head is also planned. ;Charleston has approximately 500,000 people Myrtle Beach has about 200,000 people, and another 250,000 people are spread out along the rest of the coastal strip Columbia, another metro area of around 500,000 people;The interstates have two lanes of traffic in each direction except in the metropolitan areas where they have three. Columbia does not have sufficient hotel space to accommodate the evacuees (including some coming from farther north by other routes), so some traffic continues outbound on I-26 towards Spartanburg; on I-77 north to Charlotte; and on I-20 east to Atlanta. ;The questions that need to be addressed: 1. Under what conditions does the plan for turning the two coastal-bound lanes of I-26 into two lanes of Columbia-bound traffic, essentially turning the entire I-26 into one-way traffic, significantly improve evacuation traffic flow? ;2. In 1999, the simultaneous evacuation of the states entire coastal region was ordered. Would the evacuation traffic flow
