We present a simulation model designed to determine the impact on congestion of policies for dealing with non-recurrent congestion (i.e. travel time uncertainty).

A unit root test is usually carried out by using the regression test introduced by Dickey and Fuller (1979). Under the null hypothesis the series should be a random walk. But a non-stationary series can usually be decomposed into a random walk and a stationary component. This is what is done in...

Most confidence intervals, whether based on asymptotic theory or the bootstrap, are implicitly based on inverting a Wald test. Since Wald test statistics are not invariant under nonlinear reparametrizations of the restrictions they test, confidence intervals based on them are not invariant...

We consider truncated processes, both in discrete and continuous time, and study their dynamic properties. When the underlying process is a diffusion process, we derive the infinitesimal generator of its truncated counterpart. This result is the basis for the estimation of the drift and...

The usual formulation of probit models includes, as endogenous variables, both continuous latent variables and binary … observable variables. The solution of simultaneous probit models involving only latent endogenous variables among the explanatory … variables is straightforward, provided the equations are identified. In contrast, simultaneous probit models in which the binary …
