Trip distribution is an important element of traffic impact analysis and is typically performed using expert judgment. Impacts are very sensitive to this step, and for large, mixed-use developments with many parcels, trip distribution can be very time consuming and potentially error prone. Regional trip distribution, on the other hand, is generally computed using a gravity model as part of a th...

Many traffic simulation software tools, such as Vissim, SimTraffic, Corsim, Synchro, and Dynasmart have emerged over the last decade and are widely used for analyzing capacity, delay, and level of service at intersections, ramps, and along arterial/freeway segments. While these tools have shown great promise, they are expensive and the data collection and input set-up is time consuming and reso...

The present studies were initiated to investigate the effectsof methylprednisolone(MP)onthe growthandcell kinetics of C3H/HeJ spontaneousmammarytumor. MP given every 12 hr in 9 doses at 10 or 20 mg/kg/dose resulted In temporary stasis of tumor growth with liftle or novolumeregression.Cell kineticparameterswere deter minedbyIn vitromethodsafter MP every12 hr in 3 doses. At bothdose levels a simi...

We propose a declarative-based implementation of randomised algorithms, which exploits the Constraint Logic Programming (CLP) paradigm. For the high-level formalisation of probabilistic programs expressing such algorithms we actually refer to a generalisation of CLP, namely the Probabilistic Concurrent Constraint Programming (PCCP) language, previously introduced in DW97]. This language provide...

It is demonstrated that the measured spatial separation of two objects, at rest in some inertial frame, is invariant under space-time transformations. This result holds in both Galilean and Special Relativity. A corollary is that there are no 'length contraction' or associated 'relativity of simultaneity' effects in the latter theory. A thought experiment employing four unsynchronised clocks an...

This paper describes a scalable approach to simulation of decentralized adaptive signal control systems, motivated by our interest to provide a basis for assessing the benefit of the Surtrac adaptive signal control system at a potential deployment site in advance of installation. The approach centers around a simulation controller interface called VISCO, which links the VISSIM microscopic traff...

Conversation is the most natural and popular means for people to communicate with each other. Conversation is everywhere around us, and even though you may feel that making conversation is relatively effortless, a closer look shows that a tremendous amount of sophisticated interaction is involved in initiating and sustaining conversation. Figure 1.1 illustrates a normal conversation scene in ou...

Transit usage is based on reliable and timely service. Priority is one method for maintaining reduced transit travel times and a reliable schedule, which make transit more attractive. However, with most buses operating within the same traffic lanes as other vehicle traffic, priority policy affects the surrounding traffic. Consequently, priority is often limited to minimal green time extensions ...
