Characterization of Mobile Work Zone Safety in Missouri

Evaluation of Mobile Work Zone Alarm Systems

Maintenance of highways often involves mobile work zones for various types of low speed moving operations such as striping and sweeping. The speed differential between the moving operation and traffic, and the increasing problem of distracted driving can lead to potential collisions between approaching vehicles and the truck-mounted attenuator (TMA) protecting the mobile work zone. One potentia...

Programmatic Examination of Missouri Incentive / Disincentive Contracts for 1 Mitigating Work Zone Traffic Impacts

19 Incentive/disincentive clauses (I/D) are designed to award payments to contractors if they 20 complete work ahead of schedule and to deduct payments if they exceed the completion time. A 21 previously unanswered question is, “Did the costs of the actual work zone impacts that were 22 avoided justify the incentives paid?” This paper answers that question affirmatively based on an 23 evaluatio...

Identification and characterization of the contact zone between short-tailed shrews (Blarina) in Iowa and Missouri

Short-tailed shrews (genus Blarina Gray, 1838) are characterized by divergent karyotypes and are genetically distinct. Blarina species are similar morphologically but, in most cases, can be distinguished morphometrically. Blarina distributions tend to be parapatric along well-defined contact zones; however, it has been suggested that the northern short-tailed shrew (Blarina brevicauda (Say, 182...

Making Informed Decisions on Selecting Promising Work Zone Safety Treatments

Lack of detailed and accurate safety records on incidents in Australian work zones prevents a thorough understanding of the relevant risks and hazards. Consequently it is difficult to select appropriate treatments for improving the safety of roadworkers and motorists alike. This paper presents a method for making informed decisions about safety treatments by 1) identifying safety issues and haz...
