Reducing Highway Congestion: An Empirical Approach

https://doi.org/10.3166/ejc.11.301-309Get rights and content

The California Freeway Performance Measurement System (PeMS) database stores real-time data from 26,000 loopdetectors. PeMS extracts useful information from these data and displays it in graphical or tabular form. The data provide an unparalled opportunity to assess highway performance and discover ways to improve highway management. The paper illustrates this opportunity by suggesting approaches to reduce congestion. The approaches range from bottleneck identification and effective ramp metering to questioning the current operation of high-occupancy vehicle or carpool lanes.

    Numerous studies using this model and its application to solving traffic problems have been reported [17–23]. A number of researchers have discussed methods to mitigate congestion [24–30]. The most common is ramp metering in which the rate of merging from an on-ramp is restricted [18–21].

    Note that the results of these inversions are only as good as the approximation used for the fundamental diagram. In particular, the fundamental diagram sometime fails to capture the variability of traffic in congestion (Blandin et al., 2011; Varaiya, 2005). The convexity of the solution components has been proved in Claudel and Bayen (2010b).

    Regarding large scale systems, advances have been made in recent years in the description of: (a.1) complex manufacturing systems (e.g. semiconductor manufacturing) and (a.2) large scale communication networks (e.g., WWW) (Alpcan, Basar, & Tempo, 2005). Fields of intense research activity within systems with decentralized control units are: (b.1) wireless ad-hoc networks; (b.2) vehicle traffic control (ground traffic-highways, Giridhar & Kumar, 2006; Varaiya, 2005; airplane traffic, see the Hybridge website: http://hosted.nlr.nl/public/hosted-sites/hybridge). Hybrid and event-driven (including jump parameters) stochastic systems are gaining increasing popularity mainly for their versatility in accommodating diverse needs in a number of modeling contexts.
