Decomposition of Travel Time Reliability into Various Sources: Incidents, Weather, Work Zones, Special Events, and Base Capacity
TL;DR: In this paper, an empirical, corridor-level method is proposed to divide the travel time unreliability or variability over a freeway section into the following components: incidents, weather, work zones, special events, and inadequate base capacity or bottlenecks.

Relating Travel Time Reliability and Nonrecurrent Congestion with Multistate Models
TL;DR: In this paper, the authors extend existing travel time reliability modeling in three ways, such as the feasibility of breaking down travel time distributions into different operational states, and the causal factors of the states.

TL;DR: The Travel Time Reliability Monitoring System (TTRMS) as mentioned in this paper is a travel time reliability monitoring system developed by the Strategic Highway Research Program 2 (SHRP 2) to improve the reliability of highway travel times by mitigating the effects of events that cause travel times to fluctuate unpredictably.

Heuristic Approach for Estimating Arterial Signal Phases and Progression Quality from Vehicle Arrival Data
TL;DR: The goal of this paper was to make recent arterial progression quality research implementable by developing a method to gather signal phase event data in a way that would be practical for most local transportation agencies, given their existing arterial systems.
