This paper presents an agent-based approach to design a Transportation Regulation Support System (TRSS). Based on a multi-agent modeling of a urban transportation network, the objective of our approach is to integrate the functionalities of the existing information system with the functionalities of a decision support system. The TRSS monitors the network activity and adjusts itself to the envi...

The network induced delay seriously effect the real-time and stability of CAN bus networked control systems. In this article, the structure of CAN bus NCS was analyzed, meanwhile studied the cause and integral part of delay. Then adopted TrueTime to build simulation model of CAN bus NCS. Discussed the effects of CAN bus network delay on performance of control system in three cases. Then drew a ...

In this paper, a multi-perspective decision support system (MP-DSS)‎ ‎to design hierarchical public transportation network is developed‎. ‎Since this problem depends on different perspectives‎, ‎MP-DSS consists of two sub-systems with macro and micro sub-systems based on travel information‎, ‎land use and expert knowledge‎. ‎In the micro sub-system‎, ‎two sub-modules are developed considering o...

Pedestrian safety is a major concern due to the vulnerability of pedestrians versus other traffic, especially in urban environment. The fatalities and injuries suffered in pedestrian collisions often intensify the perceived severity of these accidents. The problem is particularly significant for transit bus operations because their operations encounter pedestrian traffic regularly in their rout...

City administrators need to guarantee bus priority in urban public transportation. Building large-scale dedicated bus lanes is a cost-effective solution but it suffers from illegal utilization of dedicated bus lines by other non-permitted vehicles. In general, two systems can be utilized for bus lane monitoring: road-side system and bus mounted system. Although the former one has the advantage ...

Due to continuous urban sprawl, large-scale bus network design has become a major challenge in transport planning. The increase population and scale makes the factors considered route increasingly complex. Contemporary public transportation problems are based more on efficiency goals such as accessibility comfort of network, which increases difficulty analyzing problem. Bus is not only an NP-ha...

Investigations are described into the use of a compact, portable unit, using polychromatic scattered light, for the preliminary monitoring airborne PM 2–10 particulates over widespread urban areas subjected to vehicular traffic. The monitoring unit has been used at a city centre bus terminus, at sites along an urban bus corridor and outside a local school adjacent to an air quality monitoring s...
