2014 ITS World Congress Connected Vehicle Test Bed Demonstration Traveler Situation Data

During the 2014 ITS World Congress a demonstration of the connected vehicle infrastructure in the City of Detroit was conducted. The test site included approximately 14 intersections around Detroit’s COBO convention center and involved 9 equipped vehicles. Traveler Situation Data (TSD) was obtained from the data warehouse, and not the data clearinghouse. Only 19 messages were obtained from our query as the current mode of operation of the Test Bed is that the warehouse only contains a few static messages, which are meant to serve as a proxy for future operation in which query submissions will only return message(s) relevant to the context in which the query was submitted. The messages that returned per a query submission communicates a pertinent advisor message which is in part contextualized by location and content.

To provide insight into decoding these entries the following table will present the breakdown of a single message and summarize each of its components. As one will see in the table below, critical to decoding these entries in the translation of the ITIS codes into their meaning. To translate these codes user are advised to consult the SAE J2540 Standard. TIM messages, which are contained in this *_advisoryMessage field is comprised of three parts: Part I is header, Part II is common anchor, Part III is content, all of them are colored coded in the table below. Additionally, in the table below data element are shown in two colors, blue is for data type and red is data name.

asdBundles_asdRecords_broadcastInst_biPriorityasdbundles_asdrecords_broadcastinst_bipriorityasdbundles_asdrecords_broadcastinst_bipriorityNumberThis field contains the priority of the broadcast message, presented in an 8 bit binary string. The 5 least significant bits are reserved (and set to 0). A priority of all zeros is used for routing messages such as roadside signage where not displaying the message to the driver is only of modest impact. A value of 111xxxxx indicates a message of the highest priority. Other priorities are set according to local conventions. Values in decimal should be converted back to the 8 bit binary string and interpreted as described above. For example, a value of 32 is 00100000 in binary and corresponds to a broadcast priority of 1 (low).
