There have been few large randomised controlled trials of early intervention for children with autism spectrum disorder, even fewer with follow-up data, and none with such a lengthy follow-up period as that reported by Andrew Pickles and colleagues 1 in The Lancet. These researchers assessed long-term outcomes for children who had received a parent-mediated intervention versus treatment as usua...

Real-time traffic signal control has long been a critical way to improve congestion. Transit Signal Priority (TSP) is seen as cost-effective reduce travel time variability. Most of the previous studies develop real-time systems on vehicle basis, which unable efficiently provide preferential treatment transit vehicles. Person-based systems, transform delay computation units from passenger, have ...
