TL;DR: It is illustrated that dynamic travel time estimates can be computed with less than 10% error regardless of the data source, and that existing inductive loop detector data can significantly improve the accuracy of travel time Estimates when GPS data is sparse.
Abstract: This article experimentally assesses the influence of sensor data rates on travel time estimates computed from filtered traffic speed estimates. Using velocity data obtained from GPS smartphones and inductive loop detector data collected during the Mobile Century experiment near Berkeley, CA, and an evolution equation for average velocity along the roadway, an estimate of the traffic state is obtained via ensemble Kalman filtering. A large--scale batch of computations is run to produce estimates of traffic velocity with varying degrees of input data, and instantaneous and a posteriori dynamic travel times are compared to travel times recorded using license plate re-identification. We illustrate that dynamic travel time estimates can be computed with less than 10% error regardless of the data source, and that existing inductive loop detector data can significantly improve the accuracy of travel time estimates when GPS data is sparse.

TL;DR: An approximate theoretical method to analyze communication traffic characteristics of a cellular mobile communication system on the two-dimensional plane assuming that calls are generated by subscribers on vehicles moving along a road network.
Abstract: This paper describes an approximate theoretical method to analyze communication traffic characteristics of a cellular mobile communication system on the two-dimensional plane assuming that calls are generated by subscribers on vehicles moving along a road network. Our problems are to analyze the teletraffic characteristics of the cellular system by using the parameters indicating the vehicles' flow characteristics on the road network.

TL;DR: An exhaustive intersection control applicable for continuous traffic simulators is presented, containing many types of road crossings and junctions occurring in real road networks, including unregulated intersections without prioritization, traffic light controlled ones, intersections regulated with road signs and combinations of them with different numbers of road segments inwards and outwards.
Abstract: With the goal of accomplishing vehicular traffic simulations close to reality, modelling intersection control is a very important issue which affects the traffic flow and hence simulation results considerably. This paper presents an exhaustive intersection control applicable for continuous traffic simulators. Our work contains many types of road crossings and junctions occurring in real road networks, including unregulated intersections without prioritization (right-before-left rule), traffic light controlled ones, intersections regulated with road signs and combinations of them with different numbers of road segments inwards and outwards. Special situations such as route changes before intersections and multi-lane situations are addressed. The models are implemented for the continuous traffic simulator Traff Sim, which demonstrates their applicability and range of features. With the introduced set of rules and situations, a great majority of intersections of real road networks can be parametrized and simulated virtually and the requirements for traffic flow investigations through dynamic simulations are fulfilled.

TL;DR: A more versatile arterial traffic signal coordination method that can take into consideration of major turning traffic flows from and to cross streets is proposed, formulated as a mixed-integer linear program and solved by CPLEX.
Abstract: Traditional arterial traffic signal coordination methods are focused on providing uninterrupted flow along the arterial direction. This paper proposes a more versatile arterial traffic signal coordination method that can take into consideration of major turning traffic flows from and to cross streets. This new method is formulated as a mixed-integer linear program and solved by CPLEX. A case study based on AIMSUN simulation is conducted to demonstrate the proposed method's superiority compared to Synchro and Transyt-7F.

TL;DR: In this paper, the authors propose a traffic model inspired by dynamic queueing networks and takes into account essential features of traffic flows, focusing on flows at specific cross sections and average travel times of vehicles.
Abstract: While many classical traffic models treat the spatial extension of streets continuously or by discretization into cells of a certain length, we will subdivide roads into comparatively long homogeneous road sections of constant capacity with an inhomogeneity at the end. The related model is simple and numerically efficient. It is inspired by models of dynamic queueing networks and takes into account essential features of traffic flows. Instead of treating single vehicles or velocity profiles, it focusses on flows at specific cross sections and average travel times of vehicles.
