However, deploying sensors densely over the entire network may not be realistic for practical applications due to the budgetary constraints of traffic management agencies. This paper describes several possible spatial distributions of traffic information credibility and proposes corresponding different sensor information credibility functions to describe these spatial distribution properties. A maximum benefit model and its simplified model are proposed to solve the traffic sensor location problem. The relationships between the benefit and the number of sensors are formulated with different sensor information credibility functions. Next, expanding models and algorithms in analytic results are performed. For each case, the maximum benefit, the optimal number and spacing of sensors are obtained and the analytic formulations of the optimal sensor locations are derived as well. Finally, a numerical example is proposed to verify the validity and availability of the proposed models for solving a network sensor location problem. The results show that the optimal number of sensors of segments with different model parameters in an entire freeway network can be calculated. Besides, it can also be concluded that the optimal sensor spacing is independent of end restrictions but dependent on the values of model parameters that represent the physical conditions of sensors and roads.<\/jats:p>","DOI":"10.3390\/s16111790","type":"journal-article","created":{"date-parts":[[2016,10,27]],"date-time":"2016-10-27T14:17:52Z","timestamp":1477577872000},"page":"1790","source":"Crossref","is-referenced-by-count":2,"title":["Sensor Location Problem Optimization for Traffic Network with Different Spatial Distributions of Traffic Information"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"http:\/\/orcid.org\/0000-0002-5639-9642","authenticated-orcid":false,"given":"Xu","family":"Bao","sequence":"first","affiliation":[{"name":"Key Laboratory for Traffic and Transportation Security of Jiangsu Province, Huaiyin Institute of Technology, Huai\u2019an 223003, China"}]},{"ORCID":"http:\/\/orcid.org\/0000-0003-4912-9529","authenticated-orcid":false,"given":"Haijian","family":"Li","sequence":"additional","affiliation":[{"name":"Beijing Key Laboratory of Traffic Engineering, Beijing University of Technology, Beijing 100124, China"},{"name":"Department of Civil and Environmental Engineering, University of Wisconsin-Madison, Madison, WI 53706, USA"}]},{"ORCID":"http:\/\/orcid.org\/0000-0003-2861-4090","authenticated-orcid":false,"given":"Lingqiao","family":"Qin","sequence":"additional","affiliation":[{"name":"Department of Civil and Environmental Engineering, University of Wisconsin-Madison, Madison, WI 53706, USA"}]},{"given":"Dongwei","family":"Xu","sequence":"additional","affiliation":[{"name":"College of Information Engineering, Zhejiang University of Technology, Hangzhou 310014, China"}]},{"given":"Bin","family":"Ran","sequence":"additional","affiliation":[{"name":"Department of Civil and Environmental Engineering, University of Wisconsin-Madison, Madison, WI 53706, USA"}]},{"given":"Jian","family":"Rong","sequence":"additional","affiliation":[{"name":"Beijing Key Laboratory of Traffic Engineering, Beijing University of Technology, Beijing 100124, China"}]}],"member":"1968","published-online":{"date-parts":[[2016,10,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"254","DOI":"10.1287\/trsc.1100.0319","article-title":"An information-theoretic sensor location model for traffic origin-destination demand estimation applications","volume":"44","author":"Zhou","year":"2010","journal-title":"Transp.
