Investigation into the Effects of Gas Price and GDP on Freeway Traffic

It is well acknowledged that gas price negatively affects traffic volume while GDP (gross domestic product) may have the contrary effect. To gain in-depth understandings of such relationships, this paper collects monthly time series data of freeway traffic, gas price and GDP of Taiwan to examine short- and long-term causal relationships by Granger causality test and cointegration test, respectively. Results show that gas price Granger causes large-vehicle (truck and bus) and trailer traffic, but not small-vehicle traffic. However, there is no statistically significant finding on long-term equilibrium relationship neither between gas price and freeway traffic nor between GDP and freeway traffic.
