STING Millennium Suite (SMS) is a new web-based suite of programs and databases providing visualization and a complex analysis of molecular sequence and structure for the data deposited at the Protein Data Bank (PDB). SMS operates with a collection of both publicly available data (PDB, HSSP, Prosite) and its own data (contacts, interface contacts, surface(More)
This paper discusses first order node models for macroscopic multi-commodity traffic simulation. There are two parts: (1) input-output flow computation based on input demand, input link priorities, split ratios that define how incoming flow is distributed between output links, and output supply; and (2) a traffic assignment algorithm for the case when split(More)
We propose a macroscopic modeling framework for a network of roads and multi-commodity traffic. The proposed framework is based on the Lighthill-Whitham-Richards kinematic wave theory; more precisely, on its discretization, the Cell Transmission Model (CTM), adapted for networks and multi-commodity traffic. The resulting model is called the Link-Node CTM(More)
We propose a macroscopic modeling framework for networks of freeways equipped with managed lanes. Two types of managed lane configuration are considered: full-access, where vehicles can switch between the general purpose (GP) and the managed lanes anywhere; and separated, where such switching is allowed only at certain locations called gates. The proposed(More)
— In this paper, we present a case study on the macroscopic model calibration of the I-680 freeway in Northern California. This calibration effort posed two major challenges: 1) Only about half of the detectors on the mainline were functioning, and 2) no detection was available on the ramps. The only available ramp flow information were the Census counts on(More)
