  1. This paper, on the basis of yuelu - mountain high - tech park in changsha city, beginning with the investigation of diversiform transit - trip in the park, firstly analyzes and evaluates space - time change law of traffic flow and situation of traffic service level on actual road net - work in the park ; secondly, applying multi - statistical analysis method, taking investigated corporation as sample, using annual freight traffic volume produced by unit plant area of the corporation, with clustering analysis, obtains four sorts of the sample corporation, and establishes the predict models of freight traffic volume for every kind of corporation. with these models, actual or planning year ’ s day maximum freight traffic volume can be predicted. the third, this paper makes analysis research of trip law of employees in the park, and obtains the index of trip times, trip modes and trip development trend of the employees

    本文以長沙市嶽麓山高科技園區為依託，從調查園區內的各類交通出行開始，首先分析評價了園區內現狀道路網上的交通流時空變化規律及道路網上的交通服務水平狀況;其次是應用多元統計分析方法，以調查企業為樣品，以企業單位車間面積所產生的年貨運交通量為變量，通過聚類分析，獲得了樣本企業的四個類別，並建立了各類企業貨運交通量的預測模型，應用這些模型，可預測園區內現狀或規劃年的日最大貨運交通量;第三是對園區內企業員工的出行規律做了分析研究，獲得了企業員工的出行次數、出行方式及出行發展趨勢等等特性指標;最後是對園區內小區居民的出行狀況進行了分析，獲得了居民出行的諸如高峰時段、高峰出行量等等的特徵數據。
  2. In principle, ultrasonic sensors are suspended over a road, which keep emitting pulse signals periodically to nearby and feed back waves to decide existence of any obstacles, thus to detect the speed, height, length, different sizes ( heavy, medium and small ) of moving vehicles and accumulative flow as well as length of motorcade. optionally, it can be applied to multitude driving lanes simultaneously for traffic data. by integrating and analyzing these measured data, the necessary figures concerning traffic flow may be obtained, which are fundamental basis guiding road buildings

    本課題設計的是一種懸掛式超聲波車流多信息檢測器，通過懸掛于路面上方的超聲波探頭向路面周期性地發射脈沖信號，利用地面回波來判斷遮擋物地存在，可用於檢測行駛中的機動車車速、車高、車長、大中小分型以及累計車流量、車隊長度等信息，並可用於多個車道車流信息的同時檢測，綜合這些測量參數可獲得車流量的必要數據，可為公路建設提供必要的基礎依據。
  3. With the mathematic model of tracking beam current by velocity, real - time tracking can be obtained ; with current simulation controlling transducer and subsection linearity, precision of velocity ( error in ? 1 % ) is triumphantly can be controlled ; with inspection of the pulse numbers of switches, the position of all vehicles are checked to eliminate the error of calculating distance between all ones

    通過建立速度跟蹤束流的數學模型，較好地解決了速度跟蹤束流的實時性問題;通過採取用電流模擬量控制變頻器和分段線性處理的辦法，成功地解決了速度精度問題（誤差在士1 %內） ;通過檢測接近開關觸發的脈沖數，適時校核所有小車位置，消除各車之間距離計算誤差，從而很好地解決了距離累計計算誤差。
