Abstract | Vehicles in traffic flow are classified into two categories according
to t he car-following condition, namely isolated and non-isolated vehicles.
For the isolated vehicles, t he headway is verified to follow Negative
Exponential distribution. The headway distribution of non-isolated
vehicles is here assumed to be Lognormal distribution. One assumption is
that they are mixed with a certain ratio which is in function of headway.
This thesis attempts to present the combined Lognormal -Negative
Exponential model with such a proportion . Lognormal model itself is good
when applying to fit the observed data of headway at moderate to high
level of traffic flows while Negative Exponential model is suitable in
case of low level of flows. Advantages of both single models are employed
together in order to fit t he observed frequency of headway data passing a
point. |
