Terrifying picture shows puppy-sized spider with huge venom-filled FANGS found in the rainforest. Scientist Piotr Naskrecki was deep in a rainforest when he heard rustling from the undergrowth - it turned out to be the world's biggest spider.
ARCADY is the acronym for (Assessment of Roundabout Capacity And DelaY). This software, produced by the Transport Research Laboratory (UK), models traffic capacity, queues and delays at roundabouts.unctions is a software package by Transport Research Laboratory incorporating the ARCADY and PICADY modules which were previously separate programs. Junctions 8 was the first integrated version.

ARCADY is based on three decades of research and development by TRL and is used for predicting capacities, queues, delays (both queueing and geometric) and accident risk at roundabouts.ntry Lane Simulation. First introduced in ARCADY 8, the Entry Lane Simulation tool enables full simulation of individual entry lanes to be performed on existing ARCADY models. The user can quickly see where unbalanced queuing may occur and if lane starvation may take place.
