We develop and implement an instantaneous statistical model of emissions (CO/sub 2/, CO, HC, and NOx) and fuel consumption for light duty vehicles, which is simplified from the physical load-based approaches that are gaining in popularity. The model is calibrated for a set of vehicles driven on standard as well as aggressive driving cycles. The model is validated on another driving cycle in order to, test its estimation capabilities. The preliminary results indicate that the model gives reasonable results compared to actual measurements as well as to results obtained with CMEM, a well-known load-based emission model. Furthermore, the results indicate that the model runs fast and is relatively simple to calibrate. The model presented can be integrated with a variety of traffic models to predict the spatial and temporal distribution of traffic emissions and assess the impact of ITS traffic management strategies on travel times, emissions, and fuel consumption.","PeriodicalId":365722,"journal":{"name":"Proceedings.

The information can be either real-time or predictive. It has long been the interest of researchers to develop suitable methodologies and algorithms to obtain accurate predictive information about traffic conditions based on historical and/or current data. In this paper, the possibility of employing microscopic simulation to generate traffic and travel information that can be made available through the Internet is demonstrated The predictive information includes traffic speed, travel time and route guidance. PARAMICS, a sophisticated microscopic simulation program is used as the simulation engine behind the information generation process. The role of PARAMICS is to create a comprehensive database consisting of predictive information which is kept updated at pre-specified time intervals. The Application Programming Interface (API) of PARAMICS has been used to control and manage the whole process of information generation. The paper focuses on describing this process in detail.","PeriodicalId":365722,"journal":{"name":"Proceedings.

Fast-running traffic models are needed off-line for use in iterative approaches that imitate drivers' adaptation to changes to the network topology. The paper describes a simulation-based dynamic-equilibrium traffic assignment model. The determination of time-dependent path flows is modeled as a master problem that is solved using the method of successive averages (MSA). The determination of path travel times for a given set of path flows is the network-loading sub-problem, which is solved using the space-time queueing approach of Mahut (2000). This loading method has been shown to provide reasonably accurate results with very little computational effort. The model was applied to the Stockholm road network, which consists of 4342 links, 1980 nodes and 250 zones, representing over 11,000 turns. The results show that this model is applicable to medium-size networks with a very reasonable computation time.","PeriodicalId":365722,"journal":{"name":"Proceedings.
