Safety Evaluation of Urban Freight Deliveries using Microsimulation and Surrogate Safety Measures
The movement and delivery of goods is a necessary part of the transportation system. In urban areas, the freight deliveries to businesses and residences are often associated with a truck that double parks in front of the delivery location. Double parked trucks block a lane of traffic and force other vehicles in the traffic stream to change lanes in order to maneuver around them. In addition to causing congestion, this disruption to traffic flow affects safety, because there is an increase in the number of interactions that are forced to occur between vehicles. The proposed research seeks to quantify the effect of double parked freight delivery vehicles on traffic safety using surrogate safety measures associated with vehicle interactions.
