摘要：This paper provides insights pertaining to the validity of a regional
travel demand model in mimicking real-world travel times. The estimated
travel times from the regional travel demand model, for the
base year 2015, for Mecklenburg County in the city of Charlotte,
North Carolina (NC) were compared with travel time statistics from
a private data source, for the same year. The results indicate that the
estimated travel times from the regional travel demand model are
typically lower than the 85th percentile travel times, irrespective of
the link speed limit. The estimated travel times for the Central
Business District (CBD) area type are moderately correlated with the
travel time statistics from the private data source, irrespective of the
time of the day. For all the other area types, stronger correlations
were observed when the estimated travel times from the regional
travel demand model are compared with 10th to 50th percentile travel
times. The calculated Pearson correlation coefficients are low for
morning and evening peak periods compared to mid-day and nighttime
period, indicating the inability of the regional travel demand
model in mimicking congested traffic conditions accurately.
