Nowadays, many cities are intending to reduce the use of private vehicles. Governments are incorporating new mobility services and are adapting their parking policies to promote a more sustainable mobility, as both stra tegies are believed to have the potential to reduce private vehicle use. To understand the effects of these stra tegies, one...

Activity-based travel demand models provide a high level of detail when modeling complex travel behavior. Since stochastic simulation is used, however, this high level may induce large random fluctuations in the output, necessitating many model reruns to produce reliable output. This may become prohibitive in terms of computation time when...

Mobility as a Service (MaaS) and new mobility concepts mutually inspire each other, provide alternatives for the private car-oriented transport system as we know it, and will offer more mobility choices in a single journey than ever. This multitude of mobility choices however poses challenges in modeling the travelers’ mode choices in travel...

A public transport (PT) trip is a multimodal trip by nature: always complemented by an access and egress leg, for example cycling or walking to the PT stop. Introduction of shared modes increases the available access- and egress- options and thereby the PT system as a whole is possibly improved. In order to investigate those effects an extension...

Demand Responsive Transit (DRT) can complement the future mobility system by providing additional point-to-point connections based on requests of the users. As a consequence, the liveability of a city might decrease when DRT vehicles introduce additional congestion due to deadheading (relocation of vehicles without transporting passengers). The...

The rising Mobility as a Service (MaaS) concept integrates many new transport options for the travelling public, such as the use of public bikes and car-sharing services. As such, it offers more mobility combinations within a single journey than ever. To effectively handle the choice for such a mobility combination inside an activity-based...

Activity-based travel demand models (ABMs) are gaining popularity in the field of traffic modeling because of their high level of detail compared to traditional travel demand models. Due to this, however, ABMs have high computational requirements, making ABMs hard to use for analysis and optimization purposes. We address this problem by relying...

Propagation of sound waves in air can be considered as a special case of fluid dynamics. Consequently, the lattice Boltzmann method (LBM) for fluid flow can be used for simulating sound propagation. In this article application of the LBM to sound propagation is illustrated for various cases: free-field propagation, propagation over porous and...

Traffic noise mapping of cities requires large computer calculation times. This originates from the large number of point-to-point sound propagation calculations that must be performed. In this article it is demonstrated that noise mapping calculation times can be reduced considerably by the use of parallel computation on the Graphics Processing...

Previous studies indicate that residents may benefit from a "quiet side" to their dwellings. The influence of the level of road traffic noise exposure at the least exposed side on road traffic noise annoyance was studied in Amsterdam, The Netherlands. Road traffic noise exposure was assessed at the most and least exposed façade (Lden,most and...

For management of environmental noise, insight in the current noise situation is needed. An important source of information is provided by strategic noise maps, which can be implemented in a policy cycle on noise. However, the planning of noise measures in an urban environment is complex. Besides noise from different source types, many other...

An optimized method is presented for the numerical evaluation of the sound field generated by an incoherent line source, which is commonly used to model road and rail traffic noise. Two different solutions for the numerical integration over the line source are distinguished, a point source solution and a line source solution. With proper...

Annoyance and sleep disturbance caused by urban traffic noise are usually predicted from sound levels at the most exposed facades of dwellings. The predictions may be refined by taking into account sound levels at the other facades, in particular quiet facades. In this article a study is presented of the benefits of quiet facades in a large...

Spatial planning in urban areas is complex. Besides noise from different source types, many other aspects play a role. In order to support local authorities and others involved in spatial planning, TNO has developed an interactive instrument: 'Urban Strategy', which integrates a detailed interactive noise map with other aspects such as traffic...

A computational study of road traffic noise in cities is presented. Based on numerical boundary-element calculations of canyon-to-canyon propagation, an efficient engineering algorithm is developed to calculate the effect of multiple reflections in street canyons. The algorithm is supported by a room-acoustical analysis of the reverberant sound...

A new engineering model for sound propagation in cities is presented. The model is based on numerical and experimental studies of sound propagation between street canyons. Multiple reflections in the source canyon and the receiver canyon are taken into account in an efficient way, while weak reflections by distant buildings involving multiple...
