Requirements, Model and Prototype for a Multi-Utility Locational and Security Information Hub

This project lays the foundation for building and exchange hub for locational and security data and risk assessment of potential excavation work.  It acts primarily at 2 stages: upstream of the mark-out process, as a decision support tool to help streamline, improve and guide the mark-out process, and downstream of the mark-out to gain and preserve information gained from such field verified data, and added intelligence to each utility asset management system related to the potential proximity of other utilities, and possible criticality of proposed construction activity in a given sit

Real-time Dynamic Pricing for Bicycle Sharing Programs

This paper presents a new conceptual approach to improve the operational performance of public bike sharing systems using pricing schemes. Its methodological developments are accompanied by experimental analyses with bike demand data from Capital Bikeshare program of Washington, DC. An optimized price vector determines the incentive levels that can persuade system customers to take bicycles from, or park them at, neighboring stations so as to strategically minimize the number of unbalanced stations.

Network System Effects of Mileage Fee

This project presents a comprehensive investigation about the network effects of MF to facilitate the developments of proper MF policies. After a practice scan and a review of the recent literature on MF, a multiclass mathematical programming with equilibrium constraint (MC-MPEC) is proposed to capture the optimal MF charging problem from a network perspective. The MC-MPEC problem is then solved and tested on two illustrative networks to show the MF network effect.

Development of a Comprehensive Inventory Management System for Underground Fiber Optic Conduits

Major State Departments of Transportation operate and maintain networks of thousands of miles of conduits, many carrying fiber optic cables that are vital to State communication systems. These conduits are located alongside or across highways and frequently must be located and marked to avoid damage from digging or boring resulting from construction.

Evaluating the Role of Private Investment in Infrastructure Assets

Public Private Partnership (P3) projects are likely to fundamentally impact entire transportation systems. However, most studies are focused on system modeling rather than policy analysis, and few studies have examined the impacts of P3s on real-size transportation networks. Policy guidance for devising and administering P3 contracts to improve transportation system performance while maintaining profitability is lacking.

Effects of Overweight Vehicles on NYSDOT Infrastructure

This report develops a methodology for estimating the effects of different categories of overweight trucks on NYSDOT pavements and bridges. A data mining algorithm is used to categorize truck data collected at several Weigh-In-Motion stations around the state of New York based on the trucks’ adherence to the state’s legal weight limits. The data indicate that about 11% of the trucks traveling on New York highways may be carrying divisible load permits, 1% may be carrying special hauling permits, while about 6% may be illegally overweight.

The Game-Theoretic National Interstate Economic Model: An Integrated Framework to Quantify the Economic Impacts of Cyber-terrorist Behavior

This study suggests an integrated framework to quantify cyber attack impacts on the U.S. airport security system. A cyber attack by terrorists on the U.S. involves complex strategic behavior by the terrorists because they could plan to invade an airport electronic system without any U.S. border or entry point. At the same time, any defending entity must consider the complex processes that may cause turmoil. The possibility of simultaneous threats from cyber attacks causes another difficulty for defending entities to secure their airports.
