Book Description
In evacuation planning the capacities of the street network are usually assumed as in daily-traffic. However, such rare and unique situations induce disaster-related or traffic-related factors which affect the capacities of the street network negatively. This work focuses on a new robust evacuation concept in order to reduce the effects of such random capacity disruptions.

Book Description
National as well as state economies are contingent on their transport network reliability. Traffic demand levels are constantly on the rise and there is an urging request, by network users, for free flow travel, even if parts of the road network are congested or disrupted. To assist the evaluation, design and monitoring of road networks, existing network reliability analysis methods and techniques, should be further developed, not only from the theoretical stand point, but also for practical application. This study has examined literature on network reliability evaluation methods, approaches and metrics in order to provide a brief listing of the most cited work. In this effort, sources of other disciplines (besides Transportation Engineering) have been reviewed in an effort to explore and propose possible methods and techniques that have not been implemented in road network reliability to date. The study also proposes a game theoretical modeling approach to account for capacity uncertainty, and help decision makers to choose the optimal investment plan over all possible scenarios.

Book Description
Many books focus on individual differences and how those relate to traffic safety such as accident proneness, gender differences, age, alcohol, and the effects of drugs. Others focus on the safety effects regarding the vehicle such as airbags, anti-lock brakes, navigation systems, intelligent cruise control and other new gadgets coming to the vehicle. Even though these topics are undoubtedly important for traffic safety, this book takes a unique approach as it focuses solely on the road environment. Designing Safe Road Systems provides the background for those who want to know more about the effects of road design on driving behaviour. It uses a systems approach to allow a better understanding of why and in what circumstances drivers may commit errors. This understanding will ultimately lead to road systems that prevent (fatal) errors from occurring. The book contains an overview of the current models and theories about human performance and human behaviour in traffic that are relevant for all those involved in designing safe road systems. The central theme of this book is how design principles can reduce the probability of an error while driving. The authors demonstrate how knowledge of human factors helps a road authority to better understand how road users behave. They argue that in many cases the design of the environment can be further adjusted to human capabilities, and that safety should be considered a system property to be built into the road system.

Book Description
In today & rsquo;s congested transportation networks, disruptions like crashes may cause unexpected and significant delays. All transportation networks are vulnerable to disruptions, to some extent, with temporary or permanent effects. Vulnerability is more important in urban transportation networks, due to heavy use and road segments that are close to each other. Small disturbances on an urban transportation network segment can have a huge impact on its accessibility. Intelligent adversaries may take advantage of these vulnerable parts of the network and disrupt transportation operations, increasing the overall transportation cost for the users. Often, the decision about improving the networks in transportation planning and management is made without adequately considering the possible vulnerabilities. By considering the factor of vulnerability in their decision, planners could prevent or limit the impact of severe unforeseen disruptions. This dissertation proposes two models for designing robust networks against intelligent attackers. In both models, three stakeholders are considered: i) the network manager/designer, ii) the adversary (intelligent attacker), and iii) the network users. The frameworks of both models and some other possible models are presented in this dissertation. The first framework is a bi-objective designer model. The designer in this model has two objectives at the top level: to reduce the total system cost and to reduce the vulnerability of the network. The Sioux Falls network consists of 24 nodes and 76 links was chosen for to evaluate this framework. The decision of the designer and attacker was improving or destroying the links. Metaheuristic algorithm was used to solve the designer and attacker problems. For the user equilibrium problem, the Frank-Wolfe algorithm was implemented. The objective of the designer of the network in the first model, consist of two goals. The two goals may conflict on the amount of amount of limited available budget to be invested on the desired project/links. Therefore, a trade off solutions between these two objectives may forms. The results proved that the proposed multi-level model is able to find the Pareto front solutions for the two objectives of the designer. The second framework is a three-level zero-sum game model. In this framework, the payoffs from the designer are assumed to have the same value to the adversary entity. Therefore, the goal of this framework is to minimize the maximum gain that the adversary can achieve. An example network with 6 nodes and 16 links was used to examine this framework. The results showed that the model could be a valuable tool to reduce the potential vulnerability of networks. Other indicators of system performance can be implemented in the upper-level of this framework, in order to examine different goals. Both frameworks were tested using a medium size network with applications to larger scale networks as a future research direction.

Book Description
Efficient and effective transportation networks are backbones to modern societies. Methodologically, their design has mainly been driven by optimization approaches oftentimes with a strong cost focus. Their strategic planning, however, should go beyond detailed cost analysis and identify other key decision drivers. Transportation network centrality describes the appearance of a network; hence is crucial for network design. Anne Paul develops a strategic approach to transportation network design by conceptualizing transportation network centrality and relating it to the performance and quality of transportation networks. Consequently, the concept of network centrality serves to support decisions in strategic network design. A practical implementation of this approach is provided, demonstrating its feasibility. Potential readers include scholars and practitioners from logistics, supply chain management, and operational research with an interest in strategic transportation network design.
