One important cause for this variability in urban\n4 travel times is the delay that drivers experience at (particularly signalized) intersections. This delay\n5 can be due to the time that the driver needs to wait for the red light or the time for the queue of\n6 waiting vehicles at the intersection to dissolve, or both. As a result, the ability to capture the\n7 characteristics of the delay at signalized intersections is a critical, yet challenging, step in estimating\n8 and predicting urban link travel times. The uncertainties in these experienced delays are caused by\n9 both the traffic conditions and traffic control at the intersections. In this paper, a delay distribution\n10 model is developed for an urban trip over a route with two consecutive fixed-time controlled\n11 intersections. The proposed model captures the stochasticity in the arrival and departure process at the\n12 first intersection. The presented example illustrates how these stochastic factors influence the realized\n13 delay distribution for the two consecutive signalized intersections. Delay distributions are analyzed\n14 for different levels of mismatch of the two controlled intersections (from well coordinated to badly\n15 coordinated), and under different degrees of saturation. Finally, the predicted delay distributions are\n16 validated using the VISSIM simulation model, and show that the proposed (analytical) model can well\n17 represent the VISSIM simulation data.",

state of the road traffic and its short-term evolution for the entire road network is a basic component of ATIS (advanced traveler information systems) and ATMS (advanced traffic management system) applications. In this view the use of real-time floating-car data (FCD), based on traces of GPS positions, is emerging as a reliable and cost-effective way to gather accurate travel times/speeds in a road network and to improve short-term predictions of travel conditions. The purpose of this paper is to present a large-scale working application of FCD-system, developed and operated by OCTOTelematics, delivering real-time traffic speed information throughout the Italian motorway network and along some important arterial streets located in major Italian metropolitan areas. Traffic speed estimates are deduced at an interval of 3 minutes from GPS traces transmitted in real-time from a large number (and still growing) of privately owned cars (about 600.000) equipped with a specific device covering a range of insurance-related applications. This paper also proposes two algorithms, respectively based on artificial neural networks and pattern-matching, designed to on-line perform short-term (15 to 30 minutes) predictions of link travel speeds by using current and near-past link average speeds estimated by the OCTOTelematics FCD system. The Rome ring road (GRA-Grande Raccordo Anulare) was used for testing the feasibility of the two algorithms. Testing results showed that the proposed approaches for short-term predictions are very promising and effective.", "proceedingsTitle": "Intelligent Transportation Systems, 2008.

"abstractNote": "From past several years, the interest to use probe vehicles for traffic monitoring is growing. In\nthis paper, vehicles equipped with GPS are used as traffic sensors to collect traffic data (speeds,\npositions and time stamps) in the urban road network. However, due to the low polling frequencies,\ntravel times recorded by probe vehicles are partial link or route travel times. This paper focuses on the\nestimation complete link or route travel times. Two methods are adopted to allocate travel times\ncollected by probe vehicles between two consecutive time stamps into individual links. One method\nwas the probabilistic method developed by Hellinga (1) and the other is distance-proportion method.\nTwo field data sets are used to verify how these two methods perform in different traffic conditions.\nThe results show that for the low traffic demand condition, when the polling interval is low (e.g. 15s,\n30s), both methods can work well. In the case of a high polling interval (e.g. 60s), Hellinga’s method\nperforms worse than distance-proportion method. However, in the high traffic demand condition with\n60s polling interval, Hellinga’s method works better with Mean Absolute Percentage Error (MAPE) of\n11.64% compared with the distance-proportion method with MAPE of 17%. In Hellinga’s method, the\nlink travel time is subdivided into free flow travel time and delay. The sensitivity of the performance\nof the method to different free flow speeds is also investigated in the paper. Results show that in low\ntraffic demand condition with 60s polling interval, free flow speeds have significant influence on the\nestimation results.", "proceedingsTitle": "89th Annual Meeting Transportation Research Board", "conferenceName": "89th Annual Meeting of the Transportation Research Board", "publisher": "", "place": "", "date": "2010", "eventPlace": "", "volume": "", "issue": "", "numberOfVolumes": "", "pages": "", "series": "", "seriesNumber": "", "DOI": "", "ISBN": "", "citationKey": "", "url": "P:\\2080\\Publikationen_Literatur\\Traffic\\10-2522.pdf", "accessDate": "", "ISSN": "", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "", "libraryCatalog": "", "callNumber": "0000", "rights": "", "extra": "", "tags": [ { "tag": "intersection" }, { "tag": "link travel times" }, { "tag": "probe vehicle" }, { "tag": "urban traffic" } ], "collections": [], "relations": { "owl:sameAs": "http://zotero.org/groups/4119/items/KQW8SF4G" }, "dateAdded": "2010-12-20T08:46:04Z", "dateModified": "2010-12-20T08:46:04Z" } }, { "key": "5CHTH48I", "version": 1, "library": { "type": "group", "id": 33736, "name": "UrbanTravelTimeEstimation", "links": { "alternate": { "href": "https://www.zotero.org/groups/urbantraveltimeestimation", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/33736/items/5CHTH48I", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/urbantraveltimeestimation/items/5CHTH48I", "type": "text/html" } }, "meta": { "createdByUser": { "id": 41494, "username": "jasamer", "name": "", "links": { "alternate": { "href": "https://www.zotero.org/jasamer", "type": "text/html" } } }, "creatorSummary": "Draijer et al.", "parsedDate": "2000", "numChildren": 0 }, "data": { "key": "5CHTH48I", "version": 1, "itemType": "magazineArticle", "title": "Global Positioning System as Data\nCollection Method for Travel Research", "creators": [ { "creatorType": "author", "firstName": "Geert", "lastName": "Draijer" }, { "creatorType": "author", "firstName": "Nelly", "lastName": "Kalfs" }, { "creatorType": "author", "firstName": "Hui", "lastName": "Perdok" } ], "abstractNote": "The technology of Global Positioning Systems (GPS) provides new ways\nfor collecting information about travel behavior. When it is used in combination\nwith an electronic travel diary, valuable information of high\nquality about travel behavior becomes available. To learn about the possibilities\nof this new technology, a pilot study involving 151 people was\nperformed in the Netherlands. What makes this pilot unique is the monitoring\nof all modes of travel, not just travel by motorized vehicles. The\nfindings suggest that although it is possible to monitor all travel modes,\ndata quality differs among them. The GPS device registered nearly all\ncar driver trips, compared to half of the tram and train trips. When\ntrips are registered, public transport trips are registered with a higher\naccuracy level than car trips. For specific trips, respondents did not use\nthe equipment because of the burden placed on them or because of a\nlack of time. This was especially the case for walking, cycling, public\ntransport, shopping trips, and visits.

As more heterogeneous traffic data (e.g. from loops, probe vehicles,\nAVI systems) become available, data fusion has become one of the main challenges of state estimation (e.g.\ntraffic flow, density, speed). Given the different semantics over space and time of for example AVI data and\nlocal data from loops, data fusion is a far more complex problem than it may seem at first glance.\nIn this paper a new algorithm is presented for fusing data from local detectors (loops) with travel times\nobtained from AVI systems. This simple, but mathematically elegant algorithm called Piece-wise Inverse Speed\nCorrection by using Individual Travel-times (PISCIT) correctly and efficiently combines these (in essence\nincompatible) data and produces a state estimate (space mean speeds per cell) which is better than one obtained\nby any of the data sources individually. Moreover, we show that PISCIT is robust with respect to structural and\nrandom errors in the source data. The approach is validated using synthetic data generated by microscopic\nsimulation.
