This paper evaluates measurement methods for traffic flow variables taken at the network level. Generalized Edie's definitions of fundamental along highways are extended considering vehicles traveling in networks. These used to characterize networks and form basis estimating relationships among density, flow, speed a diagram. The method relies on three-dimensional vehicle trajectories provide estimates speed. Such may be routinely obtained from particle-based microscopic mesoscopic...
Installing charging facilities in existing parking lots city centers is considered an effective measure to encourage the adoption of plug-in electric vehicles (PEV). This article concerned with problem locating these so as minimize total system cost. The formulated a fixed charge facility location model capacity constraints. proposed extends work by allowing unserved demands and considering drivers' preference for familiar lots. Accordingly, inconvenience costs are introduced those who have...
This paper provides a discussion of network traffic flow stability and capacity including existing definitions measurement methods in the literature. To characterize flow, three phases are defined as free (F), inhomogenously congested (IC), homogenously congested. It is shown that large non-homogenous networks, F → IC transition usually hysteretic phase transition. examines effects adaptive driving on instability simulated model Chicago metropolitan area large-scale highly complex with exit...
Limited charging infrastructure for electric vehicles (EVs) is one of the main barriers to adoption these vehicles. In conjunction with limited battery range, lack leads range-anxiety, which may discourage many potential users. This problem especially important long-distance or intercity trips. Monthly traffic patterns and performance variations are two contributing factors in defining needs EV users, particularly states adverse weather conditions. Knowing this, current study focuses on...
Connected and automated vehicle technologies are expected to significantly contribute in improving mobility safety. As connected autonomous vehicles have not been used practice at large scale, there still some uncertainties relation their applications. Therefore, researchers utilize traffic simulation tools model the presence of these vehicles. There several studies on impacts connectivity automation segment level. However, only a few investigated flow network Most consider uniform...
Electric vehicles (EV) are widely seen as a sustainable alternative to gasoline decrease emissions and dependence on fossil fuels. However, range anxiety, limited range, long charging time, insufficient infrastructure have affected EVs' adoption. High-end batteries chargers can the demand respectively, increase market share. Based recently developed intercity model, this study investigates potential impact of different battery charger technologies optimal configuration for Michigan network...
This paper examines how correlations in link travel times affect reliable path finding a stochastic network. The is defined as the that requires lowest time budget to ensure given probability of on-time arrival. Such can be found by solving shortest problem considering arrival reliability (SPOTAR). SPOTAR solved approximately using an approach based on Monte Carlo simulation. A major advantage simulation-based algorithm its ability deal with correlated times. Through use real-world network,...
The aim of this study was to solve the minimum path travel time budget (MPTTB) problem, in which reliability index. This index defined as sum mean and scaled standard deviation, included covariance matrix consider correlation. Two existing solution methods literature, outer approximation algorithm Monte Carlo simulation method, were applied MPTTB problem. former method approximated hard nonlinear constraint problem by a series linear cuts generated iteratively repeatedly solved mixed integer...
Abstract This article studies the problem of locating fuel stations to minimize extra cost spent in refueling detours, which belongs a class discretionary service facility location problems. Unlike many similar problems literature, proposed model considers capacity constraints and compares different ways incorporate them formulation. Note that ignoring constraint results nonoptimal unrealistic solutions. The models are solved using both an off‐the‐shelf solver (CPLEX) specialized...

The Transit Capacity and Quality of Service Manual (TCQSM) provides transit agencies with tools for measuring system performance at different levels operation. Bus service reliability, one the key measures, has become a major concern both operators users because it significantly affects user experience quality perceptions. objective this paper is to assess existing reliability measures proposed by TCQSM develop new ones bus stop level. latter are not suggested as replacements measures;...
Abstract This study introduces a framework to maximize societal benefits associated with the autonomous vehicle (AV)‐dedicated lane implementation at large‐scale transportation networks, considering travel time savings and required investments prepare infrastructure for their deployment. To this end, bi‐level optimization problem is formulated. The upper level determines links dedicated deployment, while lower level, mesoscopic traffic simulation tool employed enable realistic representation...
