St. Charles County Transportation Plan 2030 - East-West Gateway ...

When a new interchange is built east of Callahan Rd., replacing the two signalized intersections, it
also is very likely to attract new commercial development.
Forecasts of employment are shown in Table 32 below. They include the number of jobs in the
county, the number of persons who live in the county and are employed, and the number of
employed persons who live in the county and work in the county. It confirms what is described in
Chapter II, that employment in the county has grown rapidly over the last 25 years. It also notes that
many employed persons living in the county now work in the county and the number has been
growing. However, because the amount of jobs has not grown as fast as the number of employed
persons there is still a need for many persons to commute across the Missouri River. It is expected
that this trend will continue for some time with a slight decline in the future (See Table 3, Page 5).

An important item used in forecasting travel is the number of vehicles expected in each household.
Estimates of households as well as vehicle ownership was developed using historical data and future
population. Households were estimated with population and were used to obtain the number of
vehicles that would exist. Historical data regarding vehicle registrations for 2000 and 2004 were
obtained from the states of Missouri and Illinois but older data (1990) was not comparable or used.
Table 33 below shows the number of households and registered autos in 2000 and 2004. It also
contains an estimate of households and autos for the year 2030. The data shows that the number of
autos in the region increased by 79,700, far exceeding the 33,400 increases in households. In St.
Charles County the difference between the growth in vehicles and households was more dramatic.
Vehicles increased by 49,300 or 28.0 percent while households grew by 15,700 or 15.4 percent. By
