We describe the macroscopic model components needed to adequately represent traffic network with managed lanes: multi-commodity traffic flow, policy for junctions with multiple input and multiple output links, and local traffic assignment, where vehicles of certain types may choose between multiple downstream links. We then discuss how this theory applies to modeling of freeways with HOV and HOT lanes, and show techniques that reproduce phenomena inherent to HOV/T traffic: the inertia effect and the friction effect. The inertia effect reflects drivers’ inclination to stay in their lane as long as possible and switch only if this would obviously improve their travel condition. The friction effect reflects the empirically observed drivers’ fear of moving fast in the HOV lane while traffic in the adjacent GP links moves slowly due to congestion.

www.comperra.com A Quick Product Assessment Tool W e need to do research before we buy Usually, before buying appliances we c onduct research: w e look at pr oduct ratings, browse through customer reviews , and compare features and prices of competing products. There exist tens of websites and services that enable such research. To name a few, CNET , ConsumerSearch , Consumer Reports , Digital Trends , Engadget , and not to forget Google and Amazon . To help us narrow down our p roduct ch oices , these sites d isplay product ratings, 1 to 5 stars. We tend to look at products with 4 or 5 stars and ignore those with 3 or fewer. However, even a fter this preliminary filter ing ( h ow trus tworthy and i nformative these ratin gs are is a diff erent questi on) , it is common that the list of products to choose from is still long and we have to go deeper: read reviews, compare feature

C++ objects of types that have virtual functions or virtual base classes contain volatile (‘memory’) pointers. We call such pointers ‘hidden pointers’ because they were not specified by the user. If such C++ objects are made persistent, then these pointers become invalid across program invocations. We encountered this problem in our implementation of O++, which is a database language based on C++.
