Tool For Calculating User Delay Cost Associated With Urban Arterial Construction Zone
Roadway construction work zone imposes travel delay on the road users. The monetary cost of the delay is called user delay cost (UDC). Limited work has been done on quantifying UDC in Canada and their focus were rural highways. If there is a realistic estimate of UDC, it could lead to less schedule …

Backpressure Policies for Wireless ad hoc Networks
… networking protocols to suffer. However, some user applications in ad hoc networks demand high throughput and low end-user delay. In the literature, the backpressure policy, i.e. queue backlog differential-based joint routing and scheduling, is known to be throughput-optimal with robust support …

Substantial Maintenance Practices for Bridges on the Kansas State Highway System
… Cost analysis are discussed. The findings for user cost as determined by an analysis of user delay at work zones and closures are discussed. The economic impact of allowing bridges at one site in the FY 2003 to deteriorate to restricted status for two years is reviewed.

Overloaded Array Processing: System Analysis, Signal Extraction Techniques, and Time-delay Estimation
… overloaded array processing algorithms, Multi-User Decision Feedback Equalizer (MU-DFE), Iterative Least Squares with Projection (ILSP), and Iterative Least Squares with Enumeration (ILSE). ILSE is a non-linear joint maximum-likelihood detector, is shown to demodulate many more signals than …

Optimizing work zone practices for highway construction projects
… minimize total work zone costs including agency, user delay, and expected crash costs; (5) conduct field experiments to analyze the efficiency and constructability of various arrangements of temporary rumble strips prior to and at the edge of work zones; and (6) study and enhance the effectiveness …

Statistical delay QoS driven resource allocation and performance analysis for wireless communication networks
Delay quality-of-service (QoS) guarantees play a critical role in enabling delay-sensitive wireless applications. By applying the theory of effective capacity (EC), the maximum arrival rate with a guaranteed delay-outage probability constraint, is analyzed and investigated in terms of …

Methodology for Development of Delay-Based Passenger Car Equivalents of Heavy Vehicles in Work Zones
… vehicles in work zones are developed based on delay caused by the heavy vehicles since delay captures the effects of heavy vehicles better than other parameters. A mathematical model was developed to determine the bounds on the delays in work zones. The results of the model for level terrain …

Development of Sustainable Traffic Control Principles for Self-Driving Vehicles: A Paradigm Shift Within the Framework of Social Justice
… and tries to protect the inviolability of each user in a system. Consequently, the control objective is the distribution of delay per individual, considering for example that the effect of delay is not the same if a person is traveling to a grocery store as opposed to traveling to a hospital. …

Work Zone Analysis Under Detour Settings
A new approach of work zone delay cost analysis is developed to understand the implications of detours. This method, unlike any of the previous methods, is based on the impacts within the transportation network and let users find the shortest paths which will eventually come to equilibrium. The …

Optimizing the construction planning of highway work zones
… work zones often cause traffic congestions and delays resulting in increased road user delay, traffic crashes, and vehicle emissions. The Federal Highway Administration (FHWA) and state DOTs are continuously seeking to improve work zone safety and mobility. To accomplish this, the layout of …

Development of a smartphone application to measure pavement roughness and to identify surface irregularities
… quality of a vehicle. Roughness also affects user delay costs, fuel consumption, tire, and maintenance costs. Roughness is predominantly characterized in terms of International Roughness Index (IRI), which is often measured using inertial profilers. Inertial profilers are equipped with …
