Safety

Transportation System Management and Operation (TSM&O) is a new program within the Florida Department of Transportation. It is based on measuring performance, actively managing the multimodal transportation network and delivering positive safety and mobility outcomes to the traveling public in South Florida. This technical paper describes how the program was established in South Florida and how the Department will work with local agencies to implement the program and manage a network of arterials and limited access facilities in real-time.

With continued progress in the development and implementation of driver assistance systems and vehicle warning systems, more and more sensors and components are slated to debut on the vehicle to support more and more active safety functions, making the trend to integrate multiple safety functions in a single system increasingly appealing. In this paper, we present a highly integrated stereo vision based system that successfully encompasses a variety of active safety functions in one single module. Using a megapixel stereo image sensor, we are able to generate high resolution, high dynamic range, wide field of view intensity images as well as range images for all the supported functions. Efficient computational design and hardware implementation of vision algorithms enables the system to accomplish multiple safety functions, including forward collision warning, lane departure warning, pedestrian protection, collision mitigation by braking, adaptive cruise control, traffic sign recognition, advanced headlamp control and driver alertness warning. This integrated hardware module design paves the way for more coherent and seamless cooperation and coordination of multiple feature functions, making the presented system a powerful and cost effective onboard system for active safety applications.

The Minnesota Department of Transportation (MnDOT) has undertaken the multi-year Connected Vehicle Safety, Mobility, and User Fee (CVSMUF) Project to demonstrate the utility of Connected Vehicle applications for the agency and the traveling public in Minnesota. As the name implies, the program addresses multiple transportation operational needs. The safety applications provide in-vehicle signing to supplement the driver’s view of the roadway and potential intersection conflicts; the mobility applications both collect and provide traffic data; and the user fee system demonstrates collection of mileage-based revenues while protecting the driver’s privacy. As a Connected Vehicle program, information is shared between in-vehicle and infrastructural systems through wireless communications. Unlike the majority of Connected Vehicle demonstrations, the in-vehicle components are developed entirely from aftermarket devices, the communications include both commercially-available 3G cellular and local agency-installed Dedicated Short Range Communications (DSRC), and the infrastructure ranges from the roadside to the back office. The program has developed and is deploying a set of applications to 500 volunteer test participants in the Twin Cities area. Complete results of the program will become available in 2013. Keywords: Minnesota, Connected Vehicle, safety, signing, probe, user fee, aftermarket.

This paper examines drivers use of advisory or warning messages displayed on portable Changeable Message Signs (CMS) and/or Variable Speed Limit (VSL) signs in different visibility, traffic conditions, and at two types of roadways; freeways and two-lane roads. In addition, it investigates the factors affecting drivers’ behavior in adverse visibility conditions.
