Cross-cutting Issues

This paper describes a study of the effects of road surface conditions on the driver
behaviors in the dilemma zone using a driving simulator. It is found that the driver’s decision
in the dilemma zone is heavily influenced by the road-surface conditions and vehicle’s
distance to the stop line. Results of this study also show that under the same road surface
condition there is no clear difference in vehicle approach speeds between those that stop for
the signal and those that do not stop. The insight gained from this study can be applied to
improve the existing dilemma-free control method.

Onboard displays are becoming popular as rear-seat entertainment in vehicles. However, watching video displays frequently causes car sickness in the same way as reading books in a moving vehicle. We propose two approaches to reduce car sickness while watching an onboard display. An experimental study showed that car sickness was markedly reduced by applying our proposed approaches.

The Basic available data being used to analysis the travel time reliability is collected
by the AVI detectors allocated in Ping’an Da Jie Street from Guanyuan Bridge to
Ping’anli street. And we choose the data from 7am to 9am in November as our sample
data. Why we choose that have two reasons. First, Ping’an Da Jie Street is the second
artery in Beijing, which will ensure the sample size is enough. Second, the period we
choose is the time When t he traffic is most crowded. Therefore Focus on the
reliability of this time has more practical significance. The above Figure 1 shows the
whole street and detectors allocated on it.

The paper examines, through case studies, how the use of ITS solutions can support the
delivery of urban regeneration schemes on busy urban streets in the UK. An examination is
made of the ITS measures available to support the delivery of urban regeneration projects in
the development and improvement of the urban realm. A toolkit of ITS measures is proposed
cross referenced against the key objectives for urban design as prescribed by CABE
(Commission for Architecture and the Built Environment). To demonstrate how the
utilisation of ITS supports urban regeneration and local economies three case study examples
are provided. The paper concludes that ITS solutions can provide a flexible method of
balancing priorities and road space on busy streets thereby supporting the needs of local
residents, businesses and other street based activities whilst maintaining transport operations
on the wider network.

Congestion is a serious problem on many road networks around the world and its extent and
severity are expected to increase significantly. Environmental impact and financial
constraints make conventional widening and the construction of new roads much less
appropriate. Interventions are therefore required that help to reduce congestion in an
economic and sustainable way. A combined approach of demand management and using
existing assets more efficiently - ‘Sweating the Asset’ - is needed to ‘manage movement’ in a
sustainable way. This paper discusses a series of operational regimes and interventions that
could be deployed on existing highways to increase capacity and reduce congestion.
