Performance Measurement System (PeMS) is a freeway performance measurement system
for all of California. It processes 2 GB/day of 30-s loop detector data in real time to produce …

Chapter 16, Urban Street Facilities, describes an integrated multimodal methodology for
evaluating the quality of service providedto road users traveling along an urban street. An …

Statistics from a corridor along Interstate 5 in Los Angeles show that average travel time and
travel-time variability are meaningful measures of freeway performance. Variability of travel …

A methodology and its application to measure total, recurrent, and nonrecurrent (incident
related) delay on urban freeways are described. The methodology used data from loop …

A steady-state M/M/c queueing system under batch service interruptions is introduced to
model the traffic flow on a roadway link subject to incidents. When a traffic incident happens …

Traffic incidents are recognised as one of the key sources of non-recurrent congestion that
often leads to reduction in travel time reliability (TTR), a key metric of roadway performance …

This paper presents a wavelet-based novel freeway automated incident detection algorithm
with varying threshold parameters considering the level of traffic flow. In this approach, new …

A methodology is presented for estimating and predicting the total annual traffic congestion
attributable to recurrent and nonrecurrent congestion. The methodology is applicable to …

The traffic loading of long-span bridges is governed by congestion. Real-world observations
show that congestion can take several different forms. Nevertheless, most previous studies …

Traffic incidents are a principal cause of congestion on urban freeways, reducing capacity
and creating risks for both involved motorists and incident response personnel. As incident …
