This document presents a detailed discussion of the key components of WZ RUC, input
needs, and available tools. Step-by-step procedures to derive unit costs for monetary RUC …

This paper presents a review of the approaches to estimating the work zone operational
issues: capacity and traffic delay in work zones. It first explores the factors affecting work …

Road reconstruction and the resulting work zones are considered as a major source of traffic
congestion and delays on freeways. The roadway capacity is decreased as a result of a …

Speed‐volume‐density relationship and capacity are key elements in modelling traffic
operations, designing roadways, and evaluating facility performance. This paper uses a …

The ability to estimate work zone capacity accurately is imperative because accurate
estimates are a key input to estimates of queue length and traffic delay in work zones. This …

Freeway work zone capacity has been the focus of significant research, but most studies
were limited to specific geographic regions or work zone configurations or both. To date, no …

Accurate estimation of work zone capacity is necessary for successful traffic control
management at work zones. This study uses an ensemble tree approach to estimate work …

This study aims to develop work zone speed‐flow and capacity models, which incorporate
work zone configuration factors including the number of work zones, geometrical alignment …

Non-recurrent traffic congestion has been estimated using the capacity and the number of
closed lanes in work zones and the upstream traffic demand of work zones. However, the …

This study aims to develop a truncated lognormal distribution model to predict work zone
capacity. The distribution model parameters are formulated as linear functions of road type …
