This study looked at the operations and functions performed at the Caltrans Transportation Management Centers (TMC) with focus on the data sources, data processing, and performance measures. Recommendations are made for making greater use of archived real-time archived data. These include...

With perpetual strains on resources and traffic increasing at a steady rate, transport agencies need to evaluate the road network and make informed decisions to determine which roads have the greatest risk of adverse impacts and therefore identify the roads that have the greatest case for...

With perpetual strains on resources, road agencies need to develop network-level decision-making frameworks to ensure optimum resource allocation. This is especially true for intelligent transport systems (ITS), and in particular, variable message signs (VMS), a key component of incident...

There are more requirements for business to be able to run its operations successfully in terms of legal compliance and revenue streams optimisations. Businesses are placing high demands on Information and Communication Technology (ICT) to adapt to changing conditions. However, ICT organisations...

This report models response times and delays for highway incidents, according for spacing between interchanges and the time penalty for changing directions, enabling a response vehicle to reach an incident on the opposite side of the highway. A fundamental question in dispatching incident crews...

INCISIM is a computer program that simulates the occurrence of highway incidents, the dispatching of emergency vehicles, and the traffic flow on the network. INCISIM can represent multiple types of emergency vehicles, include highway patrol cars, freeway service patrol trucks, tow trucks...

Incident-induced traffic congestion has been recognized as a critical issue to solve in the development of advanced freeway incident management systems. This paper investigates the applicability of a stochastic optimal control approach to real-time incident-responsive local ramp control on...
